+This document presents a summary of Apache Doris versions released within one year, listed in reverse chronological order.
+
+:::tip Latest Release
+
+🎉 Version 3.0.3 released now. Check out the 🔗[Release Notes](../releasenotes/v3.0/release-3.0.3) here. Starting from version 3.X, Apache Doris supports a compute-storage decoupled mode in addition to the compute-storage coupled mode for cluster deployment. With the cloud-native architecture that decouples the computation and storage layers, users can achieve physical isolation between query loads across multiple compute clusters, as well as isolation between read and write loads. 
+
+<br />
+
+🎉 Version 2.1.7 released now. Check out the 🔗[Release Notes](../releasenotes/v2.1/release-2.1.6) here. The 2.1 version delivers exceptional performance with 100% higher out-of-the-box queries proven by TPC-DS 1TB tests, enhanced data lake analytics that are 4-6 times speedier than Trino and Spark, solid support for semi-structured data analysis with new Variant types and suite of analytical functions, asynchronous materialized views for query acceleration, optimized real-time writing at scale, and better workload management with stability and runtime SQL resource tracking.

+
+In version 1.1, we realized the full vectorization of the computing layer and storage layer, and officially enabled the vectorized execution engine as a stable function. All queries are executed by the vectorized execution engine by default, and the performance is 3-5 times higher than the previous version. It increases the ability to access the external tables of Apache Iceberg and supports federated query of data in Doris and Iceberg, and expands the analysis capabilities of Apache Doris on the data lake; on the basis of the original LZ4, the ZSTD compression algorithm is added , further improves the data compression rate; fixed many performance and stability problems in previous versions, greatly improving system stability. Downloading and using is recommended.
+
+## Upgrade Notes
+
+### The vectorized execution engine is enabled by default
+
+In version 1.0, we introduced the vectorized execution engine as an experimental feature and Users need to manually enable it when executing queries by configuring the session variables through `set batch_size = 4096` and `set enable_vectorized_engine = true` .
+
+In version 1.1, we officially fully enabled the vectorized execution engine as a stable function. The session variable `enable_vectorized_engine` is set to true by default. All queries are executed by default through the vectorized execution engine.
+
+### BE Binary File Renaming
+
+BE binary file has been renamed from palo_be to doris_be . Please pay attention to modifying the relevant scripts if you used to rely on process names for cluster management and other operations.
+
+### Segment storage format upgrade
+
+The storage format of earlier versions of Apache Doris was Segment V1. In version 0.12, we had implemented Segment V2 as a new storage format, which introduced Bitmap indexes, memory tables, page cache, dictionary compression, delayed materialization and many other features. Starting from version 0.13, the default storage format for newly created tables is Segment V2, while maintaining compatibility with the Segment V1 format.
+
+In order to ensure the maintainability of the code structure and reduce the additional learning and development costs caused by redundant historical codes, we have decided to no longer support the Segment v1 storage format from the next version. It is expected that this part of the code will be deleted in the Apache Doris 1.2 version.
+
+### Normal Upgrade
+
+For normal upgrade operations, you can perform rolling upgrades according to the cluster upgrade documentation on the official website.
+
+[https://doris.apache.org//docs/admin-manual/cluster-management/upgrade](https://doris.apache.org//docs/admin-manual/cluster-management/upgrade)
+
+## Features
+
+### Support random distribution of data [experimental]
+
+In some scenarios (such as log data analysis), users may not be able to find a suitable bucket key to avoid data skew, so the system needs to provide additional distribution methods to solve the problem.
+
+Therefore, when creating a table you can set `DISTRIBUTED BY random BUCKETS number`to use random distribution, the data will be randomly written to a single tablet when importing to reduce the data fanout during the loading process. And reduce resource overhead and improve system stability.
+
+### Support for creating Iceberg external tables[experimental]
+
+Iceberg external tables provide Apache Doris with direct access to data stored in Iceberg. Through Iceberg external tables, federated queries on data stored in local storage and Iceberg can be implemented, which saves tedious data loading work, simplifies the system architecture for data analysis, and performs more complex analysis operations.
+
+In version 1.1, Apache Doris supports creating Iceberg external tables and querying data, and supports automatic synchronization of all table schemas in the Iceberg database through the REFRESH command.
+
+### Added ZSTD compression algorithm
+
+At present, the data compression method in Apache Doris is uniformly specified by the system, and the default is LZ4. For some scenarios that are sensitive to data storage costs, the original data compression ratio requirements cannot be met.
+
+In version 1.1, users can set "compression"="zstd" in the table properties to specify the compression method as ZSTD when creating a table. In the 25GB 110 million lines of text log test data, the highest compression rate is nearly 10 times, which is 53% higher than the original compression rate, and the speed of reading data from disk and decompressing it is increased by 30%.
+
+## Improvements
+
+### More comprehensive vectorization support
+
+In version 1.1, we implemented full vectorization of the compute and storage layers, including:
+
+Implemented vectorization of all built-in functions
+
+The storage layer implements vectorization and supports dictionary optimization for low-cardinality string columns
+
+Optimized and resolved numerous performance and stability issues with the vectorization engine.
+
+We tested the performance of Apache Doris version 1.1 and version 0.15 on the SSB and TPC-H standard test datasets:
+
+On all 13 SQLs in the SSB test data set, version 1.1 is better than version 0.15, and the overall performance is improved by about 3 times, which solves the problem of performance degradation in some scenarios in version 1.0;
+
+On all 22 SQLs in the TPC-H test data set, version 1.1 is better than version 0.15, the overall performance is improved by about 4.5 times, and the performance of some scenarios is improved by more than ten times;

+
+### Compaction logic optimization and real-time guarantee
+
+In Apache Doris, each commit will generate a data version. In high concurrent write scenarios, -235 errors are prone to occur due to too many data versions and untimely compaction, and query performance will also decrease accordingly.
+
+In version 1.1, we introduced QuickCompaction, which will actively trigger compaction when the data version increases. At the same time, by improving the ability to scan fragment metadata, it can quickly find fragments with too many data versions and trigger compaction. Through active triggering and passive scanning, the real-time problem of data merging is completely solved.
+
+At the same time, for high-frequency small file cumulative compaction, the scheduling and isolation of compaction tasks is implemented to prevent the heavyweight base compaction from affecting the merging of new data.
+
+Finally, for the merging of small files, the strategy of merging small files is optimized, and the method of gradient merging is adopted. Each time the files participating in the merging belong to the same data magnitude, it prevents versions with large differences in size from merging, and gradually merges hierarchically. , reducing the number of times a single file participates in merging, which can greatly save the CPU consumption of the system.
+
+When the data upstream maintains a write frequency of 10w per second (20 concurrent write tasks, 5000 rows per job, and checkpoint interval of 1s), version 1.1 behaves as follows:
+
+-   Quick data consolidation: Tablet version remains below 50 and compaction score is stable. Compared with the -235 problem that frequently occurred during high concurrent writing in the previous version, the compaction merge efficiency has been improved by more than 10 times.
+
+-   Significantly reduced CPU resource consumption: The strategy has been optimized for small file Compaction. In the above scenario of high concurrent writing, CPU resource consumption is reduced by 25%;
+
+-   Stable query time consumption: The overall orderliness of data is improved, and the fluctuation of query time consumption is greatly reduced. The query time consumption during high concurrent writing is the same as that of only querying, and the query performance is improved by 3-4 times compared with the previous version.
+
+### Read efficiency optimization for Parquet and ORC files
+
+By adjusting arrow parameters, arrow's multi-threaded read capability is used to speed up Arrow's reading of each row_group, and it is modified to SPSC model to reduce the cost of waiting for the network through prefetching. After optimization, the performance of Parquet file import is improved by 4 to 5 times.
+
+### Safer metadata Checkpoint
+
+By double-checking the image files generated after the metadata checkpoint and retaining the function of historical image files, the problem of metadata corruption caused by image file errors is solved.
+
+## Bugfix
+
+### Fix the problem that the data cannot be queried due to the missing data version.(Serious)
+
+This issue was introduced in version 1.0 and may result in the loss of data versions for multiple replicas.
+
+### Fix the problem that the resource isolation is invalid for the resource usage limit of loading tasks (Moderate)
+
+In 1.1, the broker load and routine load will use Backends with specified resource tags to do the load.
+
+### Use HTTP BRPC to transfer network data packets over 2GB (Moderate)
+
+In the previous version, when the data transmitted between Backends through BRPC exceeded 2GB,
+it may cause data transmission errors.
+
+## Others
+
+### Disabling Mini Load
+
+The `/_load` interface is disabled by default, please use `the /_stream_load` interface uniformly.
+Of course, you can re-enable it by turning off the FE configuration item `disable_mini_load`.
+
+The Mini Load interface will be completely removed in version 1.2.
+
+### Completely disable the SegmentV1 storage format
+
+Data in SegmentV1 format is no longer allowed to be created. Existing data can continue to be accessed normally.
+You can use the `ADMIN SHOW TABLET STORAGE FORMAT` statement to check whether the data in SegmentV1 format
+still exists in the cluster. And convert to SegmentV2 through the data conversion command
+
+Access to SegmentV1 data will no longer be supported in version 1.2.
+
+### Limit the maximum length of String type
+
+In previous versions, String types were allowed a maximum length of 2GB.
+In version 1.1, we will limit the maximum length of the string type to 1MB. Strings longer than this length cannot be written anymore.
+At the same time, using the String type as a partitioning or bucketing column of a table is no longer supported.
+
+The String type that has been written can be accessed normally.
+
+### Fix fastjson related vulnerabilities
+
+Update to Canal version to fix fastjson security vulnerability.
+
+### Added `ADMIN DIAGNOSE TABLET` command
+
+Used to quickly diagnose problems with the specified tablet.

+## Features
+
+### Support ODBC Sink in Vectorized Engine.
+
+This feature is enabled in non-vectorized engine but it is missed in vectorized engine in 1.1. So that we add back this feature in 1.1.1.
+
+### Simple Memtracker for Vectorized Engine.
+
+There is no memtracker in BE for vectorized engine in 1.1, so that the memory is out of control and cause OOM. In 1.1.1, a simple memtracker is added to BE and could control the memory and cancel the query when memory exceeded.
+
+## Improvements
+
+### Cache decompressed data in page cache.
+
+Some data is compressed using bitshuffle and it costs a lot of time to decompress it during query. In 1.1.1, doris will decompress the data that encoded by bitshuffle to accelerate query and we find it could reduce 30% latency for some query in ssb-flat.
+
+## Bug Fix
+
+### Fix the problem that could not do rolling upgrade from 1.0.(Serious)
+
+This issue was introduced in version 1.1 and may cause BE core when upgrade BE but not upgrade FE.
+
+If you encounter this problem, you can try to fix it with [#10833](https://github.com/apache/doris/pull/10833).
+
+### Fix the problem that some query not fall back to non-vectorized engine, and BE will core.
+
+Currently, vectorized engine could not deal with all sql queries and some queries (like left outer join) will use non-vectorized engine to run. But there are some cases not covered in 1.1. And it will cause be crash.
+
+### Compaction not work correctly and cause -235 Error.
+
+One rowset multi segments in uniq key compaction, segments rows will be merged in generic_iterator but merged_rows not increased. Compaction will failed in check_correctness, and make a tablet with too much versions which lead to -235 load error.
+
+### Some segment fault cases during query.

+
+# Upgrade Notes
+
+PageCache and ChunkAllocator are disabled by default to reduce memory usage and can be re-enabled by modifying the configuration items `disable_storage_page_cache` and `chunk_reserved_bytes_limit`.
+
+Storage Page Cache and Chunk Allocator cache user data chunks and memory preallocation, respectively.
+
+These two functions take up a certain percentage of memory and are not freed. This part of memory cannot be flexibly allocated, which may lead to insufficient memory for other tasks in some scenarios, affecting system stability and availability. Therefore, we disabled these two features by default in version 1.1.3.
+
+However, in some latency-sensitive reporting scenarios, turning off this feature may lead to increased query latency. If you are worried about the impact of this feature on your business after upgrade, you can add the following parameters to be.conf to keep the same behavior as the previous version.
+
+```
+disable_storage_page_cache=false
+chunk_reserved_bytes_limit=10%
+```
+
+* ``disable_storage_page_cache``: Whether to disable Storage Page Cache. version 1.1.2 (inclusive), the default is false, i.e., on. version 1.1.3 defaults to true, i.e., off.
+* `chunk_reserved_bytes_limit`: Chunk allocator reserved memory size. 1.1.2 (and earlier), the default is 10% of the overall memory. 1.1.3 version default is 209715200 (200MB).

+
+# Behavior Changes
+
+When alias name is same as the original column name like "select year(birthday) as birthday" and use it in group by, order by , having clause, doris's behavior is different from MySQL in the past. In this release, we make it follow MySQL's behavior. Group by and having clause will use original column at first and order by will use alias first. It maybe a litter confuse here so there is a simple advice here, you'd better not use an alias the same as original column name.

+We are more than excited to announce that, after six months of coding, testing, and fine-tuning, Apache Doris 2.0.0 is now production-ready. Special thanks to the 275 committers who altogether contributed over 4100 optimizations and fixes to the project. 
+
+This new version highlights:
+
+- 10 times faster data queries
+- Enhanced log analytic and federated query capabilities
+- More efficient data writing and updates
+- Improved multi-tenant and resource isolation mechanisms
+- Progresses in elastic scaling of resources and storage-compute separation
+- Enterprise-facing features for higher usability

+
+## **A 10 Times Performance Increase**
+
+In SSB-Flat and TPC-H benchmarking, Apache Doris 2.0.0 delivered **over 10-time faster query performance** compared to an early version of Apache Doris.
+
+![](/images/release-note-2.0.0-1.png)
+
+This is realized by the introduction of a smarter query optimizer, inverted index, a parallel execution model, and a series of new functionalities to support high-concurrency point queries.
+
+### A smarter query optimizer
+
+The brand new query optimizer, Nereids, has a richer statistical base and adopts the Cascades framework. It is capable of self-tuning in most query scenarios and supports all 99 SQLs in TPC-DS, so users can expect high performance without any fine-tuning or SQL rewriting.
+
+TPC-H tests showed that Nereids, with no human intervention, outperformed the old query optimizer by a wide margin. Over 100 users have tried Apache Doris 2.0.0 in their production environment and the vast majority of them reported huge speedups in query execution.
+
+![](/images/release-note-2.0.0-2.png)
+
+**Doc**: https://doris.apache.org/docs/dev/query-acceleration/nereids/
+
+Nereids is enabled by default in Apache Doris 2.0.0: `SET enable_nereids_planner=true`. Nereids collects statistical data by calling the Analyze command.
+
+### Inverted Index
+
+In Apache Doris 2.0.0, we introduced inverted index to better support fuzzy keyword search, equivalence queries, and range queries.
+
+A smartphone manufacturer tested Apache Doris 2.0.0 in their user behavior analysis scenarios. With inverted index enabled, v2.0.0 was able to finish the queries within milliseconds and maintain stable performance as the query concurrency level went up. In this case, it is 5 to 90 times faster than its old version. 
+
+![](/images/release-note-2.0.0-3.png)
+
+### 20 times higher concurrency capability
+
+In scenarios like e-commerce order queries and express tracking, a huge number of end data users search for a certain data record simultaneously. These are what we call high-concurrency point queries, which can bring huge pressure on the system. A traditional solution is to introduce Key-Value stores like Apache HBase for such queries, and Redis as a cache layer to ease the burden, but that means redundant storage and higher maintenance costs.
+
+For a column-oriented DBMS like Apache Doris, the I/O usage of point queries will be multiplied. We need neater execution. Thus, on the basis of columnar storage, we added row storage format and row cache to increase row reading efficiency, short-circuit plans to speed up data retrieval, and prepared statements to reduce frontend overheads.
+
+After these optimizations, Apache Doris 2.0 reached a concurrency level of **30,000 QPS per node** on YCSB on a 16 Core 64G cloud server with 4×1T hard drives, representing an improvement of **20 times** compared to its older version. This makes Apache Doris a good alternative to HBase in high-concurrency scenarios, so that users don't need to endure extra maintenance costs and redundant storage brought by complicated tech stacks.

+
+### A self-adaptive parallel execution model
+
+Apache 2.0 brought in a Pipeline execution model for higher efficiency and stability in hybrid analytic workloads. In this model, the execution of queries is driven by data. The blocking operators in all query execution processes are split into pipelines. Whether a pipeline gets an execution thread depends on whether its relevant data is ready. This enables asynchronous blocking operations and more flexible system resource management. Also, this improves CPU efficiency as the system doesn't have to create and destroy threads that much.
+
+Doc: https://doris.apache.org/docs/dev/query-acceleration/pipeline-execution-engine/
+
+**How to enable the Pipeline execution model**
+
+- The Pipeline execution engine is enabled by default in Apache Doris 2.0: `Set enable_pipeline_engine = true`.
+- `parallel_pipeline_task_num` represents the number of pipeline tasks that are parallelly executed in SQL queries. The default value of it is `0`, which means Apache Doris will automatically set the concurrency level to half the number of CPUs in each backend node. Users can change this value as they need it. 
+- For those who are upgrading to Apache Doris 2.0 from an older version, it is recommended to set the value of `parallel_pipeline_task_num` to that of `parallel_fragment_exec_instance_num` in the old version.
+
+## A Unified Platform for Multiple Analytic Workloads
+
+Apache Doris has been pushing its boundaries. Starting as an OLAP engine for reporting, it is now a data warehouse capable of ETL/ELT and more. Version 2.0 is making advancements in its log analysis and data lakehousing capabilities.  
+
+### A 10 times more cost-effective log analysis solution
+
+Apache Doris 2.0.0 provides native support for semi-structured data. In addition to JSON and Array, it now supports a complex data type: Map. Based on Light Schema Change, it also supports Schema Evolution, which means you can adjust the schema as your business changes. You can add or delete fields and indexes, and change the data types for fields. As we introduced inverted index and a high-performance text analysis algorithm into it, it can execute full-text search and dimensional analysis of logs more efficiently. With faster data writing and query speed and lower storage cost, it is 10 times more cost-effective than the common log analytic solution within the industry.
+
+![](/images/release-note-2.0.0-4.png)
+
+### Enhanced data lakehousing capabilities
+
+In Apache Doris 1.2, we introduced Multi-Catalog to allow for auto-mapping and auto-synchronization of data from heterogeneous sources. In version 2.0.0, we extended the list of data sources supported and optimized Doris for based on users' needs in production environment.
+
+![](/images/release-note-2.0.0-5.png)
+
+Apache Doris 2.0.0 supports dozens of data sources including Hive, Hudi, Iceberg, Paimon, MaxCompute, Elasticsearch, Trino, ClickHouse, and almost all open lakehouse formats. It also supports snapshot queries on Hudi Copy-on-Write tables and read optimized queries on Hudi Merge-on-Read tables. It allows for authorization of Hive Catalog using Apache Ranger, so users can reuse their existing privilege control system. Besides, it supports extensible authorization plug-ins to enable user-defined authorization methods for any catalog. 
+
+TPC-H benchmark tests showed that Apache Doris 2.0.0 is 3~5 times faster than Presto/Trino in queries on Hive tables. This is realized by all-around optimizations (in small file reading, flat table reading, local file cache, ORC/Parquet file reading, Compute Nodes, and information collection of external tables) finished in this development cycle and the distributed execution framework, vectorized execution engine, and query optimizer of Apache Doris. 
+
+![](/images/release-note-2.0.0-6.png)
+
+All this gives Apache Doris 2.0.0 an edge in data lakehousing scenarios. With Doris, you can do incremental or overall synchronization of multiple upstream data sources in one place, and expect much higher data query performance than other query engines. The processed data can be written back to the sources or provided for downstream systems. In this way, you can make Apache Doris your unified data analytic gateway.
+
+## Efficient Data Update
+
+Data update is important in real-time analysis, since users want to always be accessible to the latest data, and be able to update data flexibly, such as updating a row or just a few columns, batching updating or deleting their specified data, or even overwriting a whole data partition.
+
+Efficient data updating has been another hill to climb in data analysis. Apache Hive only supports updates on the partition level, while Hudi and Iceberg do better in low-frequency batch updates instead of real-time updates due to their Merge-on-Read and Copy-on-Write implementations.
+
+As for data updating, Apache Doris 2.0.0 is capable of:
+
+- **Faster data writing**: In the pressure tests with an online payment platform, under 20 concurrent data writing tasks, Doris reached a writing throughput of 300,000 records per second and maintained stability throughout the over 10-hour continuous writing process.
+- **Partial column update**: Older versions of Doris implements partial column update by `replace_if_not_null` in the Aggregate Key model. In 2.0.0, we enable partial column updates in the Unique Key model. That means you can directly write data from multiple source tables into a flat table, without having to concatenate them into one output stream using Flink before writing. This method avoids a complicated processing pipeline and the extra resource consumption. You can simply specify the columns you need to update.
+- **Conditional update and deletion**: In addition to the simple Update and Delete operations, we realize complicated conditional updates and deletes operations on the basis of Merge-on-Write. 
+
+## Faster, Stabler, and Smarter Data Writing
+
+### Higher speed in data writing
+
+As part of our continuing effort to strengthen the real-time analytic capability of Apache Doris, we have improved the end-to-end real-time data writing capability of version 2.0.0. Benchmark tests reported higher throughput in various writing methods:
+
+- Stream Load, TPC-H 144G lineitem table, 48-bucket Duplicate table, triple-replica writing: throughput increased by 100%
+- Stream Load, TPC-H 144G lineitem table, 48-bucket Unique Key table, triple-replica writing: throughput increased by 200%
+- Insert Into Select, TPC-H 144G lineitem table, 48-bucket Duplicate table: throughput increased by 50%
+- Insert Into Select, TPC-H 144G lineitem table, 48-bucket Unique Key table: throughput increased by 150%
+
+### Greater stability in high-concurrency data writing 
+
+The sources of system instability often includes small file merging, write amplification, and the consequential disk I/O and CPU overheads. Hence, we introduced Vertical Compaction and Segment Compaction in version 2.0.0 to eliminate OOM errors in compaction and avoid the generation of too many segment files during data writing. After such improvements, Apache Doris can write data 50% faster while **using only 10% of the memory that it previously used**.

+
+### Auto-synchronization of table schema
+
+The latest Flink-Doris-Connector allows users to synchronize an entire database (such as MySQL and Oracle) to Apache Doris by one simple step. According to our test results, one single synchronization task can support the real-time concurrent writing of thousands of tables. Users no longer need to go through a complicated synchronization procedure because Apache Doris has automated the process. Changes in the upstream data schema will be automatically captured and dynamically updated to Apache Doris in a seamless manner.

+
+## A New Multi-Tenant Resource Isolation Solution
+
+The purpose of multi-tenant resource isolation is to avoid resource preemption in the case of heavy loads. For that sake, older versions of Apache Doris adopted a hard isolation plan featured by Resource Group: Backend nodes of the same Doris cluster would be tagged, and those of the same tag formed a Resource Group. As data was ingested into the database, different data replicas would be written into different Resource Groups, which will be responsible for different workloads. For example, data reading and writing will be conducted on different data tablets, so as to realize read-write separation. Similarly, you can also put online and offline business on different Resource Groups. 
+
+![](/images/release-note-2.0.0-7.png)
+
+This is an effective solution, but in practice, it happens that some Resource Groups are heavily occupied while others are idle. We want a more flexible way to reduce vacancy rate of resources. Thus, in 2.0.0, we introduce Workload Group resource soft limit.
+
+![](/images/release-note-2.0.0-8.png)
+
+The idea is to divide workloads into groups to allow for flexible management of CPU and memory resources. Apache Doris associates a query with a Workload Group, and limits the percentage of CPU and memory that a single query can use on a backend node. The memory soft limit can be configured and enabled by the user. 
+
+When there is a cluster resource shortage, the system will kill the largest memory-consuming query tasks; when there are sufficient cluster resources, once a Workload Group uses more resources than expected, the idle cluster resources will be shared among all the Workload Groups to give full play to the system memory and ensure stable execution of queries. You can also prioritize the Workload Groups in terms of resource allocation. In other words, you can decide which tasks can be assigned with adequate resources and which not.
+
+Meanwhile, we introduced Query Queue in 2.0.0. Upon Workload Group creation, you can set a maximum query number for a query queue. Queries beyond that limit will wait for execution in the queue. This is to reduce system burden under heavy workloads.
+
+## Elastic Scaling and Storage-Compute Separation
+
+When it comes to computation and storage resources, what do users want?
+
+- **Elastic scaling of computation resources**: Scale up resources quickly in peak times to increase efficiency and scale down in valley times to reduce costs.
+- **Lower storage costs**: Use low-cost storage media and separate storage from computation.
+- **Separation of workloads**: Isolate the computation resources of different workloads to avoid preemption.
+- **Unified management of data**: Simply manage catalogs and data in one place.
+
+To separate storage and computation is a way to realize elastic scaling of resources, but it demands more efforts in maintaining storage stability, which determines the stability and continuity of OLAP services. To ensure storage stability, we introduced mechanisms including cache management, computation resource management, and garbage collection.
+
+ In this respect, we divide our users into three groups after investigation:
+
+1. Users with no need for resource scaling
+2. Users requiring resource scaling, low storage costs, and workload separation from Apache Doris
+3. Users who already have a stable large-scale storage system and thus require an advanced compute-storage-separated architecture for efficient resource scaling
+
+Apache Doris 2.0 provides two solutions to address the needs of the first two types of users.
+
+1. **Compute nodes**. We introduced stateless compute nodes in version 2.0. Unlike the mix nodes, the compute nodes do not save any data and are not involved in workload balancing of data tablets during cluster scaling. Thus, they are able to quickly join the cluster and share the computing pressure during peak times. In addition, in data lakehouse analysis, these nodes will be the first ones to execute queries on remote storage (HDFS/S3) so there will be no resource competition between internal tables and external tables.
+   1.  Doc: https://doris.apache.org/docs/dev/advanced/compute_node/
+2. **Hot-cold data separation**. Hot/cold data refers to data that is frequently/seldom accessed, respectively. Generally, it makes more sense to store cold data in low-cost storage. Older versions of Apache Doris support lifecycle management of table partitions: As hot data cooled down, it would be moved from SSD to HDD. However, data was stored with multiple replicas on HDD, which was still a waste. Now, in Apache Doris 2.0, cold data can be stored in object storage, which is even cheaper and allows single-copy storage. That reduces the storage costs by 70% and cuts down the computation and network overheads that come with storage.
+   1.  Read more: https://doris.apache.org/blog/HCDS/
+
+For neater separate of computation and storage, the VeloDB team is going to contribute the Cloud Compute-Storage-Separation solution to the Apache Doris project. The performance and stability of it has stood the test of hundreds of companies in their production environment. The merging of code will be finished by October this year, and all Apache Doris users will be able to get an early taste of it in September.
+
+## Enhanced Usability
+
+Apache Doris 2.0.0 also highlights some enterprise-facing functionalities.
+
+### Support for Kubernetes Deployment
+
+Older versions of Apache Doris communicate based on IP, so any host failure in Kubernetes deployment that causes a POD IP drift will lead to cluster unavailability. Now, version 2.0 supports FQDN. That means the failed Doris nodes can recover automatically without human intervention, which lays the foundation for Kubernetes deployment and elastic scaling.  
+
+### Support for Cross-Cluster Replication (CCR)
+
+Apache Doris 2.0.0 supports cross-cluster replication (CCR). Data changes at the database/table level in the source cluster will be synchronized to the target cluster. You can choose to replicate the incremental data or the overall data. 
+
+It also supports synchronization of DDL, which means DDL statements executed by the source cluster can also by automatically replicated to the target cluster. 
+
+It is simple to configure and use CCR in Doris. Leveraging this functionality, you can implement read-write separation and multi-datacenter replication 
+
+This feature allows for higher availability of data, read/write workload separation, and cross-data-center replication more efficiently.
+
+## Behavior Change
+
+- Use rolling upgrade from 1.2-ITS to 2.0.0, and restart upgrade from preview versions of 2.0 to 2.0.0;
+- The new query optimizer (Nereids) is enabled by default: `enable_nereids_planner=true`;
+- All non-vectorized code has been removed from the system, so the `enable_vectorized_engine` parameter no long works;
+- A new parameter `enable_single_replica_compaction` has been added;
+- datev2, datetimev2, and decimalv3 are the default data types in table creation; datav1, datetimev1, and decimalv2 are not supported in table creation;
+- decimalv3 is the default data type for JDBC and Iceberg Catalog;
+- A new data type `AGG_STATE` has been added;
+- The cluster column has been removed from backend tables;
+- For better compatibility with BI tools, datev2 and datetimev2 are displayed as date and datetime when `show create table`;
+- max_openfiles and swaps checks are added to the backend startup script so inappropriate system configuration might lead to backend failure;
+- Password-free login is not allowed when accessing frontend on localhost;
+- If there is a Multi-Catalog in the system, by default, only data of the internal catalog will be displayed when querying information schema;
+- A limit has been imposed on the depth of the expression tree. The default value is 200;
+- The single quote in the return value of array string has been changed to double quote;
+- The Doris processes are renamed to DorisFE and DorisBE.
+- The functions AES and SM4 with two arguments' behaviour changed. See more informations in [relative function docs](../../sql-manual/sql-functions/encrypt-digest-functions/sm4-encrypt.md)
+
+## Embarking on the 2.0.0 Journey
+
+To make Apache Doris 2.0.0 production-ready, we invited hundreds of enterprise users to engage in the testing and optimized it for better performance, stability, and usability. In the next phase, we will continue responding to user needs with agile release planning. We plan to launch 2.0.1 in late August and 2.0.2 in September, as we keep fixing bugs and adding new features. We also plan to release an early version of 2.1 in September to bring a few long-requested capabilities to you. For example, in Doris 2.1, the Variant data type will better serve the schema-free analytic needs of semi-structured data; the multi-table materialized views will be able to simplify the data scheduling and processing link while speeding up queries; more and neater data ingestion methods will be added and nested composite data types will be realized.

+## Improvement and Optimizations
+
+- This enhancement introduces the `read_only` and `super_read_only` variables to the database system, ensuring compatibility with MySQL's read-only modes.
+
+- When the check status is not IO_ERROR, the disk path should not be added to the broken list. This ensures that only disks with actual I/O errors are marked as broken.
+
+- When performing a Create Table As Select (CTAS) operation from an external table, convert the `VARCHAR` column to `STRING` type.
+
+- Support mapping Paimon column type "ROW" to Doris type "STRUCT"
+
+- Choose disk tolerate with little skew when creating tablet
+
+- Write editlog to `set replica drop` to avoid confusing status on follower FE
+
+- Make the schema change memory space adaptive to avoid memory over limit
+
+- Inverted index 'unicode' tokenizer supports configuration to exclude stop words

+
+## 1 Behavior change
+
+Since the inverted index is now mature and stable, it can replace the old BITMAP INDEX. Therefore, any newly created `BITMAP INDEX` will automatically switch to an `INVERTED INDEX`, while existing `BITMAP INDEX` will remain unchanged. This entire switching process is transparent to the user, with no changes to writing or querying. Additionally, users can disable this automatic switch by setting the FE configuration `enable_create_bitmap_index_as_inverted_index` to false. [#35528](https://github.com/apache/doris/pull/35528)
+
+
+## 2 Improvement and optimizations
+
+- Add Trino JDBC Catalog type mapping for JSON and TIME
+
+- FE exit when failed to transfer to (non) master to prevent unknown state and too many logs
+
+- Write audit log while doing drop stats table.
+
+- Ignore min/max column stats if table is partially analyzed to avoid inefficient query plan
+
+- Support minus operation for set like `set1 - set2`
+
+- Improve perfmance of LIKE and REGEXP clause with concat (col, pattern_str), eg. `col1 LIKE concat('%', col2, '%')`
+
+- Add query options for short circuit queries for upgrade compatibility
+

+
+## Behavior changes
+
+- No longer set the default table comment to the table type. Instead, set it to be empty by default, for example, change COMMENT 'OLAP' to COMMENT ' '.  This new behavior is more friendly for BI software that relies on table comments. [#35855](https://github.com/apache/doris/pull/35855)
+
+- Change the type of the `@@autocommit` variable from `BOOLEAN` to `BIGINT` to prevent errors from certain MySQL clients (such as .NET MySQL.Data). [#33282](https://github.com/apache/doris/pull/33282)
+
+
+## Improvements
+
+- Remove the `disable_nested_complex_type` parameter and allow the creation of nested `ARRAY`, `MAP`, and `STRUCT` types by default. [#36255](https://github.com/apache/doris/pull/36255)
+
+- The HMS catalog supports the `SHOW CREATE DATABASE` command. [#28145](https://github.com/apache/doris/pull/28145)
+
+- Add more inverted index metrics to the query profile. [#36545](https://github.com/apache/doris/pull/36545)
+
+- Cross-Cluster Replication (CCR) supports inverted indices. [#31743](https://github.com/apache/doris/pull/31743)

+
+Thanks to our community users and developers, about 1000 improvements and bug fixes have been made in Doris 2.0.3 version, including optimizer statistics, inverted index, complex datatypes, data lake, replica management.
+
+
+
+## 1 Behavior change
+
+- The output format of the complex data type array/map/struct has been changed to be consistent to the input format and JSON specification. The main changes from the previous version are that DATE/DATETIME and STRING/VARCHAR are enclosed in double quotes and null values inside ARRAY/MAP are displayed as `null` instead of `NULL`.
+  - https://github.com/apache/doris/pull/25946
+- SHOW_VIEW permission is supported. Users with SELECT or LOAD permission will no longer be able to execute the 'SHOW CREATE VIEW' statement and must be granted the SHOW_VIEW permission separately.
+  - https://github.com/apache/doris/pull/25370
+
+
+## 2 New features
+
+### 2.1 Support collecting statistics for optimizer automatically
+
+Collecting statistics helps the optimizer understand the data distribution characteristics and choose a better plan to greatly improve query performance. It is officially supported starting from version 2.0.3 and is enabled all day by default.
+
+### 2.2 Support complex datatypes for more datalake source
+- Support complex datatypes for JAVA UDF, JDBC and Hudi MOR
+  - https://github.com/apache/doris/pull/24810
+  - https://github.com/apache/doris/pull/26236

+  - https://github.com/apache/doris/pull/25364
+- Suport Paimon version 0.5
+  - https://github.com/apache/doris/pull/24985
+
+
+### 2.3 Add more builtin functions
+- Support the BitmapAgg function in new optimizer
+  - https://github.com/apache/doris/pull/25508
+- Supports SHA series digest functions
+  - https://github.com/apache/doris/pull/24342 
+- Support the BITMAP datatype in the aggregate functions min_by and max_by 
+  - https://github.com/apache/doris/pull/25430 
+- Add milliseconds/microseconds_add/sub/diff functions

+- Add some json functions: json_insert, json_replace, json_set
+  - https://github.com/apache/doris/pull/24384
+
+
+## 3 Improvement and optimizations
+
+### 3.1 Performance optimizations
+
+- When the inverted index MATCH WHERE condition with a high filter rate is combined with the common WHERE condition with a low filter rate, the I/O of the index column is greatly reduced. 
+- Optimize the efficiency of random data access after the where filter.
+- Optimizes the performance of the old get_json_xx function on JSON data types by 2~4x.
+- Supports the configuration to reduce the priority of the data read thread, ensuring the CPU resources for real-time writing.
+- Adds `uuid-numeric` function that returns largeint, which is 20 times faster than `uuid` function that returns string.
+- Optimized the performance of case when by 3x.
+- Cut out unnecessary predicate calculations in storage engine execution.
+- Accelerate count performance by pushing down count operator to storage tier.
+- Optimizes the computation performance of the nullable type in and or expressions.
+- Supports rewriting the limit operator before `join` in more scenarios to improve query performance. 
+- Eliminate useless `order by` operators from inline view to improve query performance.
+- Optimizes the accuracy of cardinality estimates and cost models in some cases. 
+- Optimized jdbc catalog predicate pushdown logic.
+- Optimized the read efficiency of the file cache when it's enable for the first time.
+- Optimizes the hive table sql cache policy and uses the partition update time stored in HMS to improve the cache hit ratio. 
+- Optimize mow compaction efficiency.
+- Optimized thread allocation logic for external table query to reduce memory usage 
+- Optimize memory usage for column reader.
+
+
+
+### 3.2 Distributed replica management improvements
+
+Distributed replica management improvements include skipping partition deletion, colocate group deletion, balance failure due to continuous write, and hot and cold seperation table balance.
+
+

+With Doris 2.1.0, our primary focus has been on optimizing analysis performance, and the results speak for themselves. We have achieved an impressive performance improvement of over 100% on the TPC-DS 1TB test dataset, making Apache Doris more capable of challenging real-world business scenarios.

+
+## Performance improvement
+
+### Smarter optimizer
+
+On the basis of V2.0, the query optimizer in Doris V2.1 comes with enhanced statistics-based inference and enumeration framework. We have upgraded the cost model and expanded the optimization rules to serve the needs of more use cases
+
+### Better heuristic optimization
+
+For data analytics at scale or data lake scenarios, Doris V2.1 provides better heuristic query plans. Meanwhile, the RuntimeFilter is more self-adaptive to enable higher performance even without statistical information.
+
+### Parallel adaptive scan
+
+Doris V2.1 has adopted parallel adaptive scan to optimize scan I/O and thus improve query performance. It can avoid the negative impact of unreasonable numbers of buckets. (This feature is currently available on the Duplicate Key model and Merge-on-Write Unique Key model.)
+
+### Local shuffle
+
+We have introduced Local Shuffle to prevent uneven data distribution. Benchmark tests show that Local Shuffle in combination with Parallel Adaptive Scan can guarantee fast query performance in spite of unreasonable bucket number settings upon table creation.
+
+### Faster INSERT INTO SELECT
+
+To further improve the performance of INSERT INTO SELECT, which is a frequent operation in ETL, we have moved forward the MemTable execution-wise to reduce data ingestion overheads. Tests show that this can double the data ingestion speed in most cases compared to V2.0.
+Improved data lake analytics capabilities
+
+## Data lake analytic performance
+
+### TPC-DS Benchmark
+
+According to TPC-DS benchmark tests (1TB) of Doris V2.1 against Trino,
+
+- Without caching, the total execution time of Doris is 56% of that of Trino V435. (717s VS 1296s)
+- Enabling file cache can further increase the overall performance of Doris by 2.2 times. (323s)
+  This is achieved by a series of optimizations in I/O, parquet/ORC file reading, predicate pushdown, caching, and scan task scheduling, etc.
+
+### SQL dialects compatibility
+
+To facilitate migration to Doris and increase its compatibility with other DBMS, we have enabled SQL dialect conversion in V2.1. ([read more](../../lakehouse/sql-dialect)) For example, by set sql_dialect = "trino" in Doris, you can use the Trino SQL dialect as you're used to, without modifying your current business logic, and Doris will execute the corresponding queries for you. Tests in user production environment show that Doris V2.1 is compatible with 99% of Trino SQL.
+
+### Arrow Flight SQL protocol
+
+As a column-oriented database compatible with MySQL 8.0 protocol, Doris V2.1 now supports the Arrow Flight SQL protocol as well so users can have fast access to Doris data via Pandas/Numpy without data serialization and deserialization. For most common data types, the Arrow Flight protocol enables tens of times faster performance than the MySQL protocol.
+
+## Asynchronous materialized view
+
+V2.1 allows creating a materialized view based on multiple tables. This feature currently supports:
+
+- Transparent rewriting: supports transparent rewriting of common operators including Select, Where, Join, Group By, and Aggregation.
+- Auto refresh: supports regular refresh, manual refresh, full refresh, incremental refresh, and partition-based refresh.
+- Materialized view of external tables: supports materialized views based on external data tables such as those on Hive, Hudi, and Iceberg; supported synchronizing data from data lakes into Doris internal tables via materialized views.
+- Direct query on materialized views: Materialized views can be regarded as the result set after ETL. In this sense, materialized views are data tables, so users can conduct queries on them directly.
+
+## Enhanced storage
+
+### Auto-increment column
+
+V2.1 supports auto-increment columns, which can ensure data uniqueness of each row. This lays the foundation for efficient dictionary encoding and query pagination. For example, for precise UV calculation and customer grouping, users often apply the bitmap type in Doris, the process of which entails dictionary encoding. With V2.1, users can first create a dictionary table using the auto-increment column, and then simply load user data into it.
+
+### Auto partition
+
+To further release burden on operation and maintenance, V2.1 allows auto data partitioning. Upon data ingestion, it detects whether a partition exists for the data based on the partitioning column. If not, it automatically creates one and starts data ingestion.
+
+### High-concurrency real-time data ingestion
+
+For data writing, a back pressure mechanism is in place to avoid execessive data versions, so as to reduce resource consumption by data version merging. In addition, V2.1 supports group commit ([read more](../../data-operate/import/import-way/group-commit-manual)), which means to accumulate multiple writing and commit them as one. Benchmark tests on group commit with JDBC ingestion and the Stream Load method present great results.
+
+## Semi-structured data analysis
+
+### A new data type: Variant
+
+V2.1 supports a new data type named Variant. It can accommodate semi-structured data such as JSON as well as compound data types that contain integers, strings, booleans, etcs. Users don't have to pre-define the exact data types for a Variant column in the table schema. The Variant type is handy when processing nested data structures.
+You can include Variant columns and static columns with pre-defined data types in the same table. This will provide you with more flexibility in storage and queries.
+Tests with ClickBench datasets prove that data in Variant columns takes up the same storage space as data in static columns, which is half of that in JSON format. In terms of query performance, the Variant type enables 8 times higher query speed than JSON in hot runs and even more in cold runs.
+
+### IP types
+
+Doris V2.1 provides native support for IPv4 and IPv6. It stores IP data in binary format, which cuts down storage space usage by 60% compared to IP string in plain texts. Along with these IP types, we have added over 20 functions for IP data processing.
+
+### More powerful functions for compound data types
+
+- explode_map: supports exploding rows into columns for the Map data type.
+- Supports the STRUCT data type in the IN predicates
+
+## Workload Management
+
+### Hard isolation of resources
+
+On the basis of the Workload Group mechanism, which imposes a soft limit on the resources that a workload group can use, Doris 2.1 introduces a hard limit on CPU resource consumption for workload groups as a way to ensure higher stability in query performance.
+
+### TopSQL
+
+V2.1 allows users to check the most resource-consuming SQL queries in the runtime. This can be a big help when handling cluster load spike caused by unexpected large queries.
+
+
+## Others
+
+### Decimal 256
+
+For users in the financial sector or high-end manufacturing, V2.1 supports a high-precision data type: Decimal, which supports up to 76 significant digits (an experimental feature, please set enable_decimal256=true.)
+
+### Job scheduler
+
+V2.1 provides a good option for regular task scheduling: Doris Job Scheduler. It can trigger the pre-defined operations on schedule or at fixed intervals. The Doris Job Scheduler is accurate to the second. It provides consistency guarantee for data writing, high efficiency and flexibility, high-performance processing queues, retraceable scheduling records, and high availability of jobs.
+
+### Support Docker fast start to experience the new version
+
+Starting from version 2.1.0, we will provide a separate Docker Image to support the rapid creation of a 1FE, 1BE Docker container to experience the new version of Doris. The container will complete the initialization of FE and BE, BE registration and other steps by default. After creating the container, it can directly access and use the Doris cluster about 1 [minute.In](http://minute.in/) this image version, the default `max_map_count`, `ulimit`, `Swap` and other hard limits are removed. It supports X64 (avx2) machines and ARM machines for deployment. The default open ports are 8000, 8030, 8040, 9030.If you need to experience the Broker component, you can add the environment variable `--env BROKER=true` at startup to start the Broker process synchronously. After startup, it will automatically complete the registration. The Broker name is `test`.
+
+Please note that this version is only suitable for quick experience and functional testing, not for production environment!
+
+## Behavior changed
+
+- The default data model is the Merge-on-Write Unique Key model. enable_unique_key_merge_on_write will be included as a default setting when a table is created in the Unique Key model.
+- As inverted index has proven to be more performant than bitmap index, V2.1 stops supporting bitmap index. Existing bitmap indexes will remain effective but new creation is not allowed. We will remove bitmap index-related code in the future.
+- cpu_resource_limit is no longer supported. It is to put a limit on the number of scanner threads on Doris BE. Since the workload group mechanism also supports such settings, the already configured cpu_resource_limit will be invalid.
+- The default value of enable_segcompaction is true. This means Doris supports compaction of multiple segments in the same rowset.
+- Audit log plug-in
+  - Since V2.1.0, Doris has a built-in audit log plug-in. Users can simply enable or disable it by setting the enable_audit_plugin parameter.
+  - If you have already installed your own audit log plug-in, you can either continue using it after upgrading to Doris V2.1, or uninstall it and use the one in Doris. Please note that the audit log table will be relocated after switching plug-in.
+  - For more details, please see the [docs](../../admin-manual/audit-plugin).

+Apache Doris 2.1.3 was officially released on May 21, 2024. This version has updated several improvements, including writing data back to Hive, materialized view, permission management and bug fixes. It further enhances the performance and stability of the system.
+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+
+
+## Feature Enhancements
+
+**1. Support writing back data to hive tables via Hive Catalog**
+
+Starting from version 2.1.3, Apache Doris supports DDL and DML operations on Hive. Users can directly create libraries and tables in Hive through Apache Doris and write data to Hive tables by executing `INSERT INTO` statements. This feature allows users to perform complete data query and write operations on Hive through Apache Doris, further simplifying the integrated lakehouse architecture.
+
+Please refer: [https://doris.apache.org/docs/lakehouse/datalake-building/hive-build/](https://doris.apache.org/docs/lakehouse/datalake-building/hive-build/)
+
+**2. Support building new asynchronous materialized views on top of existing ones**
+
+Users can create new asynchronous materialized views on top of existing ones, directly reusing pre-computed intermediate results for data processing. This simplifies complex aggregation and computation operations, reducing resource consumption and maintenance costs while further accelerating query performance and improving data availability. [#32984](https://github.com/apache/doris/pull/32984)
+
+**3. Support rewriting through nested materialized views**
+
+Materialized View (MV) is a database object used to store query results. Now, Apache Doris supports rewriting through nested materialized views, which helps optimize query performance. [#33362](https://github.com/apache/doris/pull/33362)
+
+**4. New `SHOW VIEWS` statement**
+
+The `SHOW VIEWS` statement can be used to query views in the database, facilitating better management and understanding of view objects in the database. [#32358](https://github.com/apache/doris/pull/32358)
+
+**5. Workload Group supports binding to specific BE nodes**
+
+Workload Group can be bound to specific BE nodes, enabling more refined control over query execution to optimize resource usage and improve performance. [#32874](https://github.com/apache/doris/pull/32874)
+
+**6. Broker Load supports compressed JSON format**
+
+Broker Load now supports importing compressed JSON format data, significantly reducing bandwidth requirements for data transmission and accelerating data import performance. [#30809](https://github.com/apache/doris/pull/30809)
+
+**7. TRUNCATE Function can use columns as scale parameters**
+
+The TRUNCATE function can now accept columns as scale parameters, providing more flexibility when processing numerical data. [#32746](https://github.com/apache/doris/pull/32746)
+
+**8. Add new functions `uuid_to_int` and `int_to_uuid`**
+
+These two functions allow users to convert between UUID and integer, significantly helping in scenarios that require handling UUID data. [#33005](https://github.com/apache/doris/pull/33005)
+
+**9. Add `bypass_workload_group` session variable to bypass query queue**
+
+The `bypass_workload_group` session variable allows certain queries to bypass the Workload Group queue and execute directly, which is useful for handling critical queries that require quick responses. [#33101](https://github.com/apache/doris/pull/33101)
+
+**10. Add strcmp function**
+
+The strcmp function compares two strings and returns their comparison result, simplifying text data processing. [#33272](https://github.com/apache/doris/pull/33272)
+
+**11. Support HLL functions `hll_from_base64` and `hll_to_base64`**
+
+HyperLogLog (HLL) is an algorithm for cardinality estimation. These two functions allow users to decode HLL data from a Base64-encoded string or encode HLL data as a Base64 string, which is very useful for storing and transmitting HLL data. [#32089](https://github.com/apache/doris/pull/32089)
+
+## Optimization and Improvements
+
+**1. Replace SipHash with XXHash to improve shuffle performance**
+
+Both SipHash and XXHash are hashing functions, but XXHash may provide faster hashing speeds and better performance in certain scenarios. This optimization aims to improve performance during data shuffling by adopting XXHash. [#32919](https://github.com/apache/doris/pull/32919)
+
+**2. Asynchronous materialized views support NULL partition columns in OLAP tables**
+
+This enhancement allows asynchronous materialized views to support NULL partition columns in OLAP tables, enhancing data processing flexibility.[#32698](https://github.com/apache/doris/pull/32698)
+
+**3. Limit maximum string length to 1024 when collecting column statistics to control BE memory usage**
+
+Limiting the string length when collecting column statistics prevents excessive data from consuming too much BE memory, helping maintain system stability and performance. [#32470](https://github.com/apache/doris/pull/32470)
+
+**4. Support dynamic deletion of Bitmap cache to improve performance**
+
+Dynamically deleting no longer needed Bitmap Cache can free up memory and improve system performance. [#32991](https://github.com/apache/doris/pull/32991)
+
+**5. Reduce memory usage during ALTER operations**
+
+Reducing memory usage during ALTER operations improves the efficiency of system resource utilization. [#33474](https://github.com/apache/doris/pull/33474)
+
+**6. Support constant folding for complex types**
+
+Supports constant folding for Array/Map/Struct complex types.[#32867](https://github.com/apache/doris/pull/32867)
+
+**7. Add support for Variant type in Aggregate Key Model**
+
+The Variant data type can store multiple data types. This optimization allows aggregation operations on Variant type data, enhancing the flexibility of semi-structured data analysis. [#33493](https://github.com/apache/doris/pull/33493)
+
+**8. Support new inverted index format in CCR** [#33415](https://github.com/apache/doris/pull/33415)
+
+**9. Optimize rewriting performance for nested materialized views** [#34127](https://github.com/apache/doris/pull/34127)
+
+**10. Support decimal256 type in row-based storage format**
+
+Supporting the decimal256 type in row-based storage extends the system's ability to handle high-precision numerical data. [#34887](https://github.com/apache/doris/pull/34887)
+
+## Behavioral Changes
+
+**1. Authorization**
+
+- **Grant_priv permission changes**: `Grant_priv` can no longer be arbitrarily granted. When performing a `GRANT` operation, the user not only needs to have `Grant_priv` but also the permissions to be granted. For example, to grant `SELECT` permission on `table1`, the user needs both `GRANT` permission and `SELECT` permission on `table1`, enhancing security and consistency in permission management. [#32825](https://github.com/apache/doris/pull/32825)
+
+- **Workload group and resource usage_priv**: `Usage_priv` for Workload Group and Resource is no longer global but limited to Resource and Workload Group, making permission granting and usage more specific. [#32907](https://github.com/apache/doris/pull/32907)
+
+- **Authorization for operations**: Operations that were previously unauthorized now have corresponding authorizations for more detailed and comprehensive operational permission control. [#33347](https://github.com/apache/doris/pull/33347)
+
+**2. LOG directory configuration**
+
+The log directory configuration for FE and BE now uniformly uses the `LOG_DIR` environment variable. All other different types of logs will be stored with `LOG_DIR` as the root directory. To maintain compatibility between versions, the previous configuration item `sys_log_dir` can still be used. [#32933](https://github.com/apache/doris/pull/32933)
+
+**3. S3 Table Function (TVF)**
+
+Due to issues with correctly recognizing or processing S3 URLs in certain cases, the parsing logic for object storage paths has been refactored. For file paths in S3 table functions, the `force_parsing_by_standard_uri` parameter needs to be passed to ensure correct parsing. [#33858](https://github.com/apache/doris/pull/33858)
+
+## Upgrade Issues
+
+Since many users use certain keywords as column names or attribute values, the following keywords have been set as non-reserved, allowing users to use them as identifiers. [#34613](https://github.com/apache/doris/pull/34613)
+
+## Bug Fixes
+
+**1. Fix no data error when reading Hive tables on Tencent Cloud COSN**
+
+Resolved the no data error that could occur when reading Hive tables on Tencent Cloud COSN, enhancing compatibility with Tencent Cloud storage services.
+
+**2. Fix incorrect results returned by `milliseconds_diff` function**
+
+Fixed an issue where the `milliseconds_diff` function returned incorrect results in some cases, ensuring the accuracy of time difference calculations. [#32897](https://github.com/apache/doris/pull/32897)
+
+**3. User-defined variables should be rorwarded to the Master node**
+
+Ensured that user-defined variables are correctly passed to the Master node for consistency and correct execution logic across the entire system. [#33013]https://github.com/apache/doris/pull/33013
+
+**4. Fix Schema Change issues when adding complex type columns**
+
+Resolved Schema Change issues that could arise when adding complex type columns, ensuring the correctness of Schema Changes. [#31824](https://github.com/apache/doris/pull/31824)
+
+**5. Fix data loss issue in Routine Load when FE Master node changes**
+
+`Routine Load` is often used to subscribe to Kafka message queues. This fix addresses potential data loss issues that may occur during FE Master node changes. [#33678](https://github.com/apache/doris/pull/33678)
+
+**6. Fix Routine Load failure when Workload Group cannot be found**
+
+Resolved an issue where `Routine Load` would fail if the specified Workload Group could not be found. [#33596](https://github.com/apache/doris/pull/33596)
+
+**7. Support column string64 to avoid join failures when string size overflows unit32**
+
+In some cases, string sizes may exceed the unit32 limit. Supporting the `string64` type ensures correct execution of string JOIN operations. [#33850](https://github.com/apache/doris/pull/33850)
+
+**8. Allow Hadoop users to create Paimon Catalog**
+
+Permitted authorized Hadoop users to create Paimon Catalogs.[#33833](https://github.com/apache/doris/pull/33833)
+
+**9. Fix `function_ipxx_cidr` function issues with constant parameters**
+
+Resolved problems with the `function_ipxx_cidr` function when handling constant parameters, ensuring the correctness of function execution.[#33968](https://github.com/apache/doris/pull/33968)
+
+**10. Fix file download errors when restoring using HDFS**
+
+Resolved "failed to download" errors encountered during data restoration using HDFS, ensuring the accuracy and reliability of data recovery. [#33303](https://github.com/apache/doris/issues/33303)
+
+**11. Fix column permission issues related to hidden columns**
+
+In some cases, permission settings for hidden columns may be incorrect. This fix ensures the correctness and security of column permission settings. [#34849](https://github.com/apache/doris/pull/34849)
+
+**12. Fix issue where Arrow Flight cannot obtain the correct IP in K8s deployments**
+
+This fix resolves an issue where Arrow Flight cannot correctly obtain the IP address in Kubernetes deployment environments.[#34850](https://github.com/apache/doris/pull/34850)

+**Apache Doris version 2.1.4 was officially released on June 26, 2024.** In this update, we have optimized various functional experiences for data lakehouse scenarios, with a focus on resolving the abnormal memory usage issue in the previous version. Additionally, we have implemented several improvemnents and bug fixes to enhance the stability.  Welcome to download and use it.
+
+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+
+## Behavior changes
+
+- Non-existent files will be ignored when querying external tables such as Hive. [#35319](https://github.com/apache/doris/pull/35319)
+
+  The file list is obtained from the meta cache, and it may not be consistent with the actual file list.
+  
+  Ignoring non-existent files helps to avoid query errors.
+
+- By default, creating a Bitmap Index will no longer be automatically changed to an Inverted Index. [#35521](https://github.com/apache/doris/pull/35521)
+
+  This behavior is controlled by the FE configuration item `enable_create_bitmap_index_as_inverted_index`, which defaults to false.
+
+- When starting FE and BE processes using `--console`, all logs will be output to the standard output and differentiated by prefixes indicating the log type. [#35679](https://github.com/apache/doris/pull/35679)
+
+	For more infomation, please see the documentations:
+	
+	- [Log Management - FE Log](../admin-manual/log-management/fe-log.md)
+
+	- [Log Management - BE Log](../admin-manual/log-management/be-log.md)
+
+- If no table comment is provided when creating a table, the default comment will be empty instead of using the table type as the default comment. [#36025](https://github.com/apache/doris/pull/36025)
+
+- The default precision of DECIMALV3 has been adjusted from (9, 0) to (38, 9) to maintain compatibility with the version in which this feature was initially released. [#36316](https://github.com/apache/doris/pull/36316)

+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+## Behavior changes
+
+- The default connection pool size for the JDBC Catalog has been increased from 10 to 30 to prevent connection exhaustion in high-concurrency scenarios. [#37023](https://github.com/apache/doris/pull/37023). 
+
+- The system's reserved memory (low water mark) has been adjusted to `min(6.4GB, MemTotal * 5%)` to mitigate BE OOM issues.
+
+- When processing multiple statements in a single request, only the last statement's result is returned if the `CLIENT_MULTI_STATEMENTS` flag is not set.
+
+- Direct modifications to data in asynchronous materialized views are no longer permitted.[#37129](https://github.com/apache/doris/pull/37129)
+
+- A session variable `use_max_length_of_varchar_in_ctas` has been added to control the behavior of varchar and char type length generation during CTAS (Create Table As Select). The default value is true. When set to false, the derived varchar length is used instead of the maximum length. [#37284](https://github.com/apache/doris/pull/37284)
+
+- Statistics collection now defaults to enabling the functionality of estimating the number of rows in Hive tables based on file size. [#37694](https://github.com/apache/doris/pull/37694)
+
+- Transparent rewrite for asynchronous materialized views is now enabled by default. [#35897](https://github.com/apache/doris/pull/35897)
+
+- Transparent rewrite utilizes partitioned materialized views. If partitions fail, the base tables are unioned with the materialized view to ensure data correctness. [#35897](https://github.com/apache/doris/pull/35897)
+
+## New features
+
+### Lakehouse
+
+- The session variable `read_csv_empty_line_as_null` can be used to control whether empty lines are ignored when reading CSV format files. [#37153](https://github.com/apache/doris/pull/37153) 
+
+  By default, empty lines are ignored. When set to true, empty lines will be read as rows where all columns are null.
+
+- Compatibility with Presto's complex type output format can be enabled by setting `serde_dialect="presto"`. [#37253](https://github.com/apache/doris/pull/37253)
+
+### Multi-Table Materialized View
+
+- Supports non-deterministic functions in materialized view building. [#37651](https://github.com/apache/doris/pull/37651)
+
+- Atomically replaces definitions of asynchronous materialized views. [#37147](https://github.com/apache/doris/pull/37147)
+
+- Views creation statements can be viewed via `SHOW CREATE MATERIALIZED VIEW`. [#37125](https://github.com/apache/doris/pull/37125)
+
+- Transparent rewrites for multi-dimensional aggregation and non-aggregate queries. [#37436](https://github.com/apache/doris/pull/37436) [#37497](https://github.com/apache/doris/pull/37497)
+
+- Supports DISTINCT aggregations with key columns and partitioning for roll-ups. [#37651](https://github.com/apache/doris/pull/37651)  
+
+- Support for partitioning materialized views to roll up partitions using `date_trunc` [#31812](https://github.com/apache/doris/pull/31812) [#35562](https://github.com/apache/doris/pull/35562)
+
+- Partitioned table-valued functions (TVFs) are supported. [#36479](https://github.com/apache/doris/pull/36479)
+
+### Semi-Structured Data Management
+
+- Tables using the VARIANT type now support partial column updates. [#34925](https://github.com/apache/doris/pull/34925)
+
+- PreparedStatement support is now enabled by default. [#36581](https://github.com/apache/doris/pull/36581)
+
+- The VARIANT type can be exported to CSV format. [#37857](https://github.com/apache/doris/pull/37857)
+
+- `explode_json_object` function transposes JSON Object rows into columns. [#36887](https://github.com/apache/doris/pull/36887)
+
+- The ES Catalog now maps ES NESTED or OBJECT types to the Doris JSON type.[#37101](https://github.com/apache/doris/pull/37101)
+
+- By default, support_phrase is enabled for inverted indexes with specified analyzers to improve the performance of match_phrase series queries. [#37949](https://github.com/apache/doris/pull/37949)
+
+### Query Optimizer
+
+- Support for explaining `DELETE FROM` statements. [#37100](https://github.com/apache/doris/pull/37100)
+
+- Support for hint form of constant expression parameters [#37988](https://github.com/apache/doris/pull/37988)
+
+### Memory Management
+

+
+### Permissions
+
+- Support for authorization of resources within Table-Valued Functions (TVFs) [#37132](https://github.com/apache/doris/pull/37132)

+## Improvements
+
+### Lakehouse
+
+- Upgraded Paimon to version 0.8.1
+
+- Fixes ClassNotFoundException for org.apache.commons.lang.StringUtils when querying Paimon tables. [#37512](https://github.com/apache/doris/pull/37512)

+
+- Improved default connection logic for SQLServer JDBC Catalog. [#36971](https://github.com/apache/doris/pull/36971)
+
+  By default, the connection encryption settings are not intervened. Only when `force_sqlserver_jdbc_encrypt_false` is set to true, encrypt=false is forcibly added to the JDBC URL to reduce authentication errors. This allows for more flexible control over encryption behavior, enabling it to be turned on or off as needed.
+
+- Added serde properties to the show create table statements for Hive tables. [#37096](https://github.com/apache/doris/pull/37096)
+
+- Changed the default cache time for Hive table lists on the FE from 1 day to 4 hours

+
+- When creating a table using CTAS+TVF, partition columns in the TVF are automatically mapped to Varchar(65533) instead of String, allowing them to be used as partition columns for internal tables [#37161](https://github.com/apache/doris/pull/37161)
+
+- Optimized the number of metadata accesses for Hive write operations [#37127](https://github.com/apache/doris/pull/37127)

+
+- Improved error messages when connecting to Oracle using older versions of the ojdbc driver [#37634](https://github.com/apache/doris/pull/37634)
+
+- When Hudi tables return an empty set during Incremental Read, Doris now also returns an empty set instead of error [#37636](https://github.com/apache/doris/pull/37636)
+
+- Fixed an issue where inner-outer table join queries could lead to FE timeouts in some cases [#37757](https://github.com/apache/doris/pull/37757)
+
+- Fixed an issue with FE metadata replay errors during upgrades from older versions to newer versions when the Hive metastore event listener is enabled. [#37757](https://github.com/apache/doris/pull/37757)

+
+- Improve planning speed for transparent rewrites. [#37935](https://github.com/apache/doris/pull/37935)
+
+- When calculating the availability of asynchronous materialized views, the current refresh status is no longer taken into account. [#36617](https://github.com/apache/doris/pull/36617)
+
+### Semi-Structured Data Management
+
+- Optimize DESC performance for viewing VARIANT sub-columns through sampling. [#37217](https://github.com/apache/doris/pull/37217)
+
+- Support for special JSON data with empty keys in the JSON type. [#36762](https://github.com/apache/doris/pull/36762)
+
+### Inverted Index
+
+- Reduce latency by minimizing the invocation of inverted index exists to avoid delays in accessing object storage. [#36945](https://github.com/apache/doris/pull/36945)
+
+- Optimize the overhead of the inverted index query process. [#35357](https://github.com/apache/doris/pull/35357)
+
+- Prevent inverted indices in materialized views. [#36869](https://github.com/apache/doris/pull/36869)
+
+### Query Optimizer
+
+- When both sides of a comparison expression are literals, the string literal will attempt to convert to the type of the other side. [#36921](https://github.com/apache/doris/pull/36921)

+## Upgrade suggestions
+
+When upgrading Doris, please follow the principle of not skipping two minor versions and upgrade sequentially.
+
+For example, if you are upgrading from version 0.15.x to 2.0.x, it is recommended to first upgrade to the latest version of 1.1, then upgrade to the latest version of 1.2, and finally upgrade to the latest version of 2.0.
+
+For more upgrade information, see the documentation: [Cluster Upgrade](../../admin-manual/cluster-management/upgrade)

+
+We are excited to announce the release of Apache Doris 3.0! 
+
+**Starting from version 3.X, Apache Doris supports a compute-storage decoupled mode in addition to the compute-storage coupled mode for cluster deployment. With the cloud-native architecture that decouples the computation and storage layers, users can achieve physical isolation between query loads across multiple compute clusters, as well as isolation between read and write loads. Additionally, users can take advantage of low-cost shared storage systems such as object storage or HDFS to significantly reduce storage costs.**
+
+Version 3.0 marks a milestone in the evolution of Apache Doris towards a unified data lake and data warehouse architecture. This version introduces the ability to write data back to data lakes, allowing users to perform data analysis, sharing, processing, and storage operations across multiple data sources within Apache Doris. With capabilities such as asynchronous materialized views, Apache Doris can serve as a unified data processing engine for enterprises, helping users better manage data across lakes, warehouses, and databases. Also, Apache Doris 3.0 introduces the Trino Connector. It allows users to quickly connect or adapt to more data sources, and leverage the high-performance compute engine of Doris to deliver faster query results than Trino.
+
+Version 3.0 also enhances support for ETL batch processing scenarios, adding explicit transaction support for operations like `insert into select`, `delete` and `update`. The observability of query execution has also been improved.
+
+In terms of performance, we have improved the framework capabilities, infrastructure, and rules of the query optimizer in version 3.0. This provides optimized performance, which has been proven by blind testing in more complex and diverse business scenarios.
+
+The adaptive Runtime Filter computation method now accurately estimates filters based on data size during execution, delivering better performance under large data volumes and high loads. Additionally, asynchronous materialized view has been more stable and user-friendly in query acceleration and data modeling. 
+
+**During the development of version 3.0, over 200 contributors submitted nearly 5,000 optimizations** and fixes to Apache Doris. Contributors from companies such as VeloDB, Baidu, Meituan, ByteDance, Tencent, Alibaba, Kwai, Huawei, and Tianyi Cloud actively collaborated with the community, contributing test cases from real-world use cases to help us improve Apache Doris. We extend our heartfelt thanks to all the contributors involved in the development, testing, and feedback process for this release.

+## 1. Compute-storage decoupled mode
+
+Since V3.0, Apache Doris supports the compute-storage decoupled mode. Users can choose between it and the compute-storage coupled mode during cluster deployment.
+
+In the compute-storage decoupled mode, the BE nodes no longer store the data, but instead, a shared storage layer (HDFS and object storage) is introduced as the shared data storage layer. The computing and storage resources can be scaled independently, bringing multiple benefits to users:
+
+- **Workload isolation**: Multiple compute clusters can share the same data, allowing users to isolate different business workloads or offline loads using separate compute clusters.
+
+- **Reduced storage costs**: The full dataset is stored in the more cost-effective and highly reliable shared storage, with only hot data cached locally. Compared to the compute-storage coupled mode with three data replicas, the storage cost can be reduced by up to 90%.
+
+- **Elastic computing resources**: Since no data is stored on the BE nodes, the computing resources can be scaled flexibly based on the load requirements. Users can scale in or out an individual compute cluster or increase/decrease the number of compute clusters. This also leads to cost savings.
+
+- **Improved system robustness**: By storing the data in shared storage, Doris no longer needs to handle the complex logic of multi-replica consistency, thus simplifying distributed storage complexity and improving the overall system robustness.
+
+- **Flexible data sharing and cloning**: The flexibility of the compute-storage decoupled mode extends beyond a single Doris cluster. Tables from one Doris cluster can be easily cloned to another Doris cluster, with just metadata replication.
+
+### 1-1. From coupled to decoupled
+
+In the compute-storage coupled mode, the Apache Doris architecture consists of two main process types: Frontend (FE) and Backend (BE). The FE is primarily responsible for user request access, query parsing and planning, metadata management, and node management. The BE is responsible for data storage and query plan execution. 
+
+The BE nodes employ an MPP (Massively Parallel Processing) distributed computing architecture, leveraging a multi-replica consistency protocol to ensure high service availability and high data reliability.
+
+![From coupled to decoupled](/images/storage-compute-decoupled.PNG)
+
+
+The maturation of emerging cloud computing infrastructure, including public clouds, private clouds, and Kubernetes-based container platforms, has driven the need for cloud-native capabilities. Increasingly, users are seeking deeper integration between Apache Doris and cloud computing infrastructure to provide more elasticity.
+
+**To address this need, the VeloDB team has designed and implemented a cloud-native version of Apache Doris that decouples compute and storage, known as VeloDB Cloud.  After extensive production testing and refinement across hundreds of enterprises over a long time, this cloud-native solution has now been contributed to the Apache Doris community, manifesting as the Apache Doris 3.0 in the compute-storage decoupled mode.**
+
+In the compute-storage decoupled mode, the Apache Doris architecture consists of three layers:
+
+- **Meta data layer**: A new Meta Service module has been introduced to provide meta data services, such as processing database and table information, schemas, rowset meta, and transactions. The Meta Service is stateless and horizontally scalable. In V3.0, all of the BE's meta data and parts of the FE's meta data have been migrated to the Meta Service. We will finish the migration of the remains in future versions.
+- **Computation layer**: The stateless BE nodes execute query plans and cache a portion of the data and tablet meta data locally to improve query performance. Multiple stateless BE nodes can be organized into a computing resource pool (i.e., compute cluster), and multiple compute clusters can share the same data and metadata service. The compute clusters can be elastically scaled by adding or removing nodes as needed.
+- **Shared storage layer**: Data is persisted to the shared storage layer, which currently supports HDFS as well as various cloud-based object storage systems that are compatible with the S3 protocol, such as S3, OSS, GCS, Azure Blob, COS, BOS, and MinIO.
+
+![From coupled to decoupled-2](/images/storage-compute-decoupled-2.JPEG)
+
+### 1-2 Design highlight
+
+The design of the compute-storage decoupled mode of Apache Doris highlights the transformation of the FE's in-memory metadata model into a shared metadata service. This approach offers a globally consistent state view, allowing any node to directly submit writes without needing to go through the FE for publishing. During write operations, data is stored in shared storage, while metadata is managed by the metadata service. **This effectively controls the number of small files in shared storage. Meanwhile, the real-time write performance for individual tables is nearly on par with that in the compute-storage coupled mode. The system's overall write capacity is no longer limited by the processing power of a single FE node.**
+
+![Design highlight](/images/design-hightlight.PNG)
+
+Based on the globally consistent state view, for data garbage collection, we have adopted a design approach for data deletion that is easier to prove correct and more efficient.
+
+Specifically, data in the shared storage is incorporated into the globally consistent view offered by the shared meta data service. Whenever data is generated, we bind it to a separate, independent transaction. Similarly, for a meta data deletion operation, we also bind it to a separate, independent transaction. The purpose of this approach is to ensure that deletion and write operations cannot succeed together. The view records which data needs to be deleted, and the asynchronous deletion process can simply perform a forward deletion of the data based on the transaction records, without the need for reverse garbage collection.
+
+As the tablet-related meta data in the FE is gradually migrated to the shared meta data service, the scalability of the Doris cluster will no longer be constrained by the memory capacity of a single FE node. Building upon the shared meta data service and the forward data deletion technique, we can conveniently expand functionality such as data sharing and lightweight cloning.
+
+### 1-3 Comparison with alternative solutions
+
+Another design of decoupling compute and storage in the industry is to store the data and BE node meta data in a shared object storage or HDFS. However, this approach brings the following problems:
+
+- **Inability to support real-time writes**: During data writes, the data is mapped to tablets based on the partitioning and bucketing rules, generating segment files and rowset meta data. During the write process, a two-phase commit (Publish) is performed through the FE. When a BE node receives the Publish request, it then sets the rowset as visible. The Publish operation must not fail. If the rowset meta data is stored in the shared storage, the total small file data during the real-time write process would triple the size of the actual data files - one replica of data files, one for rowset meta data, and another for rowset meta data changes during Publish. The Publish operation is driven by a single FE node, so the write capacity of a single table or even the entire system is limited by the FE node's capabilities.
+  
+  ![Comparison with alternative solutions](/images/comparison-with-alternative-solutions.png)
+
+  We compared the real-time data write performance of Apache Doris 3.0 with the above-described solution. We simulated 500 concurrent tasks writing 10,000 data files with 500 rows each, and 50 concurrent tasks writing 250 data files with 20,000 rows each, using the same computational resources. 
+
+  **The results showed that at 50 concurrent tasks, the micro-batch write performances of Apache Doris in both compute-storage coupled and decoupled modes were almost identical, while the industry solution lagged behind Apache Doris by a factor of 100.** 
+
+  At 500 concurrent tasks, the performance of Apache Doris in the compute-storage decoupled mode showed slight degradation, but it still maintained an 11X advantage over the industry solution. To ensure a fair test, Apache Doris did not enable the Group Commit feature (which the industry solution lacks). Enabling Group Commit would further enhance real-time write performance.
+
+  ![Comparison with alternative solutions](/images/real-time-write-performance..png)
+
+  Additionally, the industry solution also faces stability and cost issues in terms of real-time data ingestion:
+
+  - Stability concerns: A large number of small files can put pressure on the shared storage, especially HDFS, and introduce stability risks.
+
+  - High object storage request costs: Some public cloud object storage services charge 10 times more for Put and Delete operations compared to Get operations. A large number of small files can lead to a significant increase in object storage request costs, which can even exceed the storage costs.
+
+- **Limited scalability**: Use cases of the compute-storage decoupled model often handles larger data storage sizes, since the FE (Frontend) meta data is entirely in-memory, when the number of tablets reaches a certain high level (e.g. tens of millions), the FE's memory pressure can become a bottleneck that limits the overall write throughput of the system.
+
+- **Potential data deletion logic issues**: In the compute-storage decoupled architecture, data is stored with one single replica. Therefore, the data deletion logic is critical for the system's reliability. The conventional approach of cross-system data deletion by comparing the differences can be challenging. During the write process, there is no way to completely avoid deletion and write from succeeding together, which can lead to data loss. Additionally, when the storage system experiences anomalies, the input used for difference calculation may be incorrect, which potentially leads to unintended data deletion.
+
+- **Data sharing and lightweight cloning**: The flexibility of the decoupled storage-compute architecture can enable future data sharing and lightweight data cloning, reducing the burden of enterprise data management. However, if each cluster has a separate FE, after cloning data across clusters, it becomes difficult to accurately determine which data is no longer referenced and can be safely deleted, as calculating cross-cluster references can easily lead to unintended data deletion.
+
+By evolving the FE's full in-memory meta data model into a shared meta data service, Apache Doris 3.0 avoids all the aforementioned issues.
+
+### 1-4 Query performance comparison
+
+In the compute-storage decoupled mode, data needs to be read from the remote shared storage system, the main bottleneck has become the network bandwidth instead of the disk I/O in the compute-storage coupled mode. 
+
+To accelerate data access, Apache Doris has implemented a high-speed caching mechanism based on local disks, and provides two cache management policies: LRU (Least Recently Used) and TTL (Time-To-Live). The newly imported data is asynchronously written to the cache to accelerate the first-time access to the latest data. If the data required by a query is not in the cache, the system will read the data from the remote storage into memory and synchronously write it to the cache for subsequent queries.
+
+In use cases involving multiple compute clusters, Apache Doris provides a cache preheating function. When a new compute cluster is established, users can choose to preheat specific data (such as tables or partitions) to further improve query efficiency.
+
+In this context, we have conducted performance tests with different caching strategies in both the compute-storage coupled and decoupled modes, using the TPC-DS 1TB test dataset. The results are concluded as follows:
+
+- When the cache is fully hit (i.e., all the data required for the query is loaded into the cache), **the query performance of the compute-storage decoupled mode is on par with that of the compute-storage coupled mode**.
+
+- When the cache is partially hit (i.e., the cache is cleared before the test, and data is gradually loaded into the cache during the test, with performance continuously improving), the query performance of the compute-storage decoupled mode is about 10% lower than that of the compute-storage coupled mode. This test scenario is the most similar to the real-life use cases.
+
+- When the cache is completely missed (i.e., the cache is cleared before every SQL execution, simulating an extreme case), the performance loss is around 35%. **Even so, Apache Doris in the compute-storage decoupled mode delivers much higher performance than its alternative solutions.**
+
+![Query performance comparison](/images/query-performance-comparison.png)
+
+### 1-5 Write speed comparison
+
+In terms of write performance, we have simulated two test cases under the same computing resources: batch import and high-concurrency real-time import. The comparison of write performance between the compute-storage coupled mode and the compute-storage decoupled mode is as follows:
+
+- **Batch import**: When importing the 1TB TPC-H and 1TB TPC-DS test datasets, **the write performance of the compute-storage decoupled mode is 20.05% and 27.98% higher than the compute-storage coupled mode**, respectively, under the single-replica configuration. During batch import, the segment file size is generally in the range of tens to hundreds of MB. In the compute-storage decoupled mode, the segment files are split into smaller files and concurrently uploaded to the object storage, which can result in higher throughput compared to writing to local disks. In real-life deployments, the compute-storage coupled mode typically uses three replicas, which means the write speed advantage of the compute-storage decoupled mode will be even more pronounced.
+
+- **High-concurrency real-time import**: as described in the "Comparison with alternative solutions" section.
+
+![Write speed comparison](/images/write-speed-comparison.png)
+
+### 1-6 Tips for production environment
+
+- **Performance**: For real-time data analysis, users can achieve query performance comparable to the compute-storage coupled mode by specifying a TTL (Time-To-Live) for the cache and writing newly ingested data into the cache. To prevent query jitter, users can cache the data generated by background tasks such as compaction and schema changes based on how frequently used the data is.
+
+- **Workload isolation**: Users can achieve physical resource isolation for different business using multiple compute clusters. For workload isolation within a single compute cluster, users can utilize the Workload Group mechanism to limit and isolate resources for different queries.
+
+### 1-7 Notes
+
+- Apache Doris 3.0 does not support the co-existence of the compute-storage coupled mode and the compute-storage decoupled mode. Users need to specify one of them during cluster deployment.
+
+- If users need the compute-storage coupled mode, following the [documentation](https://doris.apache.org/docs/3.0/install/source-install/compilation-with-docker/) for its deployment and upgrade. We recommend using Doris Manager for quick deployment and cluster upgrades. However, the compute-storage decoupled mode does not yet support Doris Manager deployment and upgrade. We will continue iteration for better support in future versions.
+
+- Currently Apache Doris does not support in-place upgrade from V2.1 to the compute-storage decoupled mode of V3.0. For such purpose, users need to perform data migration using tools like X2Doris after deploying the compute-storage decoupled clusters. In the future, we will support migration without service interruption through the CCR (Change Data Capture) capability.

+
+## 2. Data lakehouse
+
+Apache Doris is positioned as a real-time data warehouse, but it is much more than that. In previous versions, we have consistently pushed beyond the boundaries of traditional data warehouse capabilities, advancing towards a unified data lakehouse. Version 3.0 marks a milestone in this journey, with its capabilities in the lakehouse architecture becoming fully mature. We believe that a unified lakehouse is identified by **boundaryless data** and **lakehouse fusion**:
+
+**Boundaryless data: Apache Doris serves as a unified query processing engine, breaking down data barriers across different systems. It provides a consistent and ultra-fast analysis experience across all data sources, including data warehouses, data lakes, data streams, and local data files.**
+
+- **Lakehouse query acceleration**: Without the need to migrate data to Apache Doris, users can leverage Doris’ efficient query engine to directly query data stored in data lakes such as Iceberg, Hudi, Paimon, and offline data warehouses like Hive, thereby accelerating query analysis.
+
+- **Federated analysis**: By extending its catalog and storage plugins, Apache Doris enhances its federated analysis capabilities, allowing users to perform unified analysis across multiple heterogeneous data sources without physically centralizing the data in a single storage system. This enables external table queries and federated joins between internal and external tables, breaking down data silos and providing globally consistent data insights.
+
+- **Data lake construction**: Apache Doris introduces write-back functionality for Hive and Iceberg, allowing users to directly create Hive and Iceberg tables through Doris and write data into them. This allows users to write internal table data back to the offline lakehouse or process offline lakehouse data using Doris and save the results back into the lakehouse, simplifying and streamlining the data lake construction process.
+
+**Lakehouse fusion: As data lake architectures become increasingly complex, the costs of technology selection and maintenance rise for users. Achieving consistent fine-grained access control across multiple systems also becomes challenging, and real-time performance suffers. To address this, Apache Doris integrates core features of the data lake, transforming itself into a lightweight, efficient, native real-time lakehouse.**
+
+- **Real-time data updates**: Starting with version 1.2, Apache Doris enhanced the primary key model by introducing Merge-on-Write, supporting real-time updates. This feature allows high-frequency, real-time data updates based on primary key changes from upstream data sources.
+
+- **Data science and** **AI** **computation support**: From version 2.1, Apache Doris, using the efficient Arrow Flight protocol, increased the openness of its storage system and its support for various compute loads, enabling data science and AI computations.
+
+- **Enhancements for semi-structured and unstructured Data**: Apache Doris has introduced support for data types like Array, Map, Struct, JSON, and Variant, with plans to support vector indexing in the future.
+
+- **Improved resource efficiency by decoupling storage and compute**: With version 3.0, Apache Doris supports a decoupled storage and compute mode, further improving resource efficiency and scalability.
+
+### 2-1 Faster queries in the data lakehouse
+
+TPC-H and TPC-DS benchmarking proves that Apache Doris achieves average query performance that is 3 to 5 times faster than Trino/Presto.
+
+In V3.0, we have focused on optimizing query performance for production environments, including:
+
+- **More granular task splitting strategy**: By adjusting the consistent hashing algorithm and introducing a task sharding weighting mechanism, we ensure balanced query loads across all nodes.
+
+- **Scheduling optimizations for use cases with numerous partitions and files**: For cases with a large number of files (over 1 million), we have largely reduced query latency (from 100 seconds to 10 seconds) and alleviated memory pressure on the Frontend (FE) by asynchronously and batch-fetching file shards.
+
+We will continue to specifically enhance query acceleration performance in real-world business scenarios, improve the actual user experience, and build an industry-leading lakehouse query acceleration engine.
+
+### 2-2 Federated analysis: more data connectors
+
+Previous versions of Apache Doris support connectors for over 10 mainstream data lakehouses, warehouses, and relational databases. In V3.0, we have introduced the Trino Connector compatibility framework, which expands the range of data sources that Apache Doris can connect to. With this framework, users can easily adapt their existing setups to access corresponding data sources using Doris and leverage its high-speed computing engine for data analysis.
+
+Currently, Doris has completed adaptations for Delta Lake, Kudu, BigQuery, Kafka, TPCH, and TPCDS. We also encourage contributions from developers to prolong this list.

+
+### 2-3 Data lake building
+
+In V3.0, we have introduced data writeback functionality for Hive and Iceberg. This allows users to create Hive and Iceberg tables directly through Doris and write data into these tables, and enables users to perform data analysis, sharing, processing, and storage operations across multiple data sources within Doris.
+
+In future iterations, Apache Doris will further enhance support for data lake table formats and improve the openness of storage APIs.

+
+## 3. Upgraded semi-structured data analysis capabilities
+
+In versions 2.0 and 2.1, Apache Doris introduced some well-embraced features such as inverted index, NGram Bloom Filter, and Variant data type to support high-performance full-text search and multi-dimensional analysis. With them, the storage and processing of complex semi-structured data have been more flexible and efficient.
+
+In V3.0, we have further enhanced the capabilities in this scenario.
+
+After extensive testing in production environments, the Variant data type has gained sufficient stability and become the preferred choice for JSON data storage and analysis. In V3.0, we have made multiple optimizations to it:
+
+- Support for indexing of the Variant data type to accelerate queries, including inverted index, Bloom Filter index, and the built-in ZoneMap index.
+
+- Support for flexible partial column updates for Unique Key tables containing the Variant data type.
+
+- Support for the use of the Variant data type in the compute-storage decoupled mode, with optimizations of its metadata storage.
+
+- Support for exporting the Variant data type to formats such as Parquet and CSV.
+
+The inverted index, introduced since V2.0, has reached a high level of maturity after more than a year of refinement and is now running in production environments of hundreds of enterprises. In V3.0, we have made multiple optimizations to the inverted index:
+
+- After performance optimizations, including lock concurrency, Apache Doris outperforms Elasticsearch in key metrics such as query latency and concurrency in real-time reporting analysis.
+
+- Optimized index file in the compute-storage decoupled mode to reduce remote storage calls and decrease index query latency.
+
+- Support for the Array data type to accelerate the `array_contains` queries.
+
+- Enhanced the `match_phrase_*` functionality, including support for slop and phrase prefix matching `match_phrase_prefix`.
+
+## 4. Enhanced ETL capabilities
+
+### 4-1. Transaction improvements
+
+Data processing in data warehouses often involves multiple data changes that need to be handled as a single transaction. V3.0 provides explicit transaction support for `insert into select`, `delete`, and `update` operations. Example cases include:
+
+- **Transactional requirements**: For example, when updating data within a time range, the typical approach is to first delete the data in that time range, and then insert the new data. Considering that the data might already be in service, there is a need to ensure that queries visit either the old data or the new data. Thus, it can be achieved by executing the `delete` and `insert into select` operations in a transaction.
+
+  ```Java
+  BEGIN;
+  DELETE FROM table WHERE date >= "2024-07-01" AND date <= "2024-07-31";
+  INSERT INTO table SELECT * FROM stage_table;
+  COMMIT;
+  ```
+
+- **Simplified the processing of failed tasks**: For example, when two `insert into select` operations are executed within a single transaction, if any of the operations fail, it can be retried directly.
+  
+  ```Java
+  BEGIN WITH LABEL label_etl_1;
+  INTO table1 SELECT * FROM stage_table1;
+  INSERT INTO table SELECT * FROM stage_table;
+  COMMIT;
+  ```

+:::
+
+### 4-2. Improved observability
+
+- **Real-time profile retrieval**: In previous versions, due to issues with the execution plan or the data, some complex queries might have high computational requirements, so developers can only access the query profile for performance analysis after the completion of the query. This makes it hard to promptly identify issues in query execution to guarantee stability of the production environment. Now, with the ability to retrieve real-time profiles, V3.0 allows users to monitor query execution as the query is running. It also allows them to better monitor the progress of each ETL job.
+
+- **`backend_active_tasks` system table**: The `backend_active_tasks` system table provides real-time resource consumption information for each query on each BE node. Users can analyze this system table using SQL to obtain the resource usage of each query, which helps identify large queries or abnormal workloads.
+
+## 5. Asynchronous materialized view
+
+In V3.0, asynchronous materialized view is faster and more stable. It is also more user-friendly for query acceleration and data modeling scenarios. We have restructured the logic for transparent rewrite and expanded its capabilities, making it 2X faster.
+
+### 5-1 Refresh
+
+- Support for incremental update of materialized views by partitions and partition roll-ups on materialized views to allow refreshes at different granularities.
+
+- Support for nested materialized views, which is useful in data modeling scenarios.
+
+- Support for index creation and sort key specification in asynchronous materialized views, which will improve query performance after the materialized view is hit.
+
+- Higher usability of materialized view DDL with support for atomically replacing materialized views, allowing modifications to the materialized view definition SQL while keeping the materialized view available. 
+
+- Support for non-deterministic functions in materialized views to better serve daily materialized view creation.
+
+- Support for trigger-based materialized view refresh, which ensures data consistency in data modeling with nested materialized views.
+
+- Support for a broader range of SQL patterns for building partitioned materialized views, making the incremental update capability available to more use cases.
+
+### 5-2 Refresh stability
+
+- V3.0 supports specifying a Workload Group for building materialized views. This is to limit the resources used by the materialized view build process and ensure that sufficient resources remain available for ongoing queries.
+
+### 5-3 Transparent rewrite
+
+- Support for transparent rewrite of more Join types, including derived Joins. Even when there is a mismatch of Join types between the query and materialized view, transparent rewrite can still be performed by compensating with additional predicates, as long as the materialized view can provide all the data needed for the query.
+
+- Support for more aggregate functions for roll-up as well as rewrite of multi-dimensional aggregations like GROUPING SETS, ROLLUP, and CUBE; support rewriting queries with aggregations when the materialized view does not contain aggregations, simplifying Join operations and expression computation.
+
+- Support for transparent rewrite of nested materialized views, enabling higher performance for complex queries.
+
+- For partially invalid partitioned materialized views, V3.0 supports `Union All` the base tables for data completion, expanding the applicability of partitioned materialized views.
+
+### 5-4 Transparent rewrite performance
+
+- Continuous optimization has been done to improve the transparent rewrite performance, achieving 2X the speed compared to version 2.1.0.

+
+## 6. Performance improvement
+
+### 6-1 Smarter optimizer
+
+In V3.0, the query optimizer has been enhanced in terms of framework capabilities, distributed plan support, optimizer infrastructure, and rule expansion. It provides better optimization capabilities for more complex and diverse business scenarios, with higher blind test performance for complex SQL:
+
+- **Improved plan enumeration capability**: The key structure Memo for plan enumeration has been restructured and normalized. This improves the efficiency of the Cascades framework in plan enumeration and the possibility of producing better plans. Additionally, it fixes incomplete column pruning during the Join Reorder process in older versions, which led to unnecessary overhead of the Join operator, thus improving the execution performance in the relevant scenarios.
+
+- **Improved distributed plan support**: The distributed query plan has been enhanced to allow aggregation, join, and window function operations to more intelligently identify the data characteristics of intermediate computation results, avoiding ineffective data redistribution operations. Meanwhile, we have optimized the execution under the multi-replica continuous execution mode, making it more data cache-friendly.
+
+- **Improved optimizer infrastructure**: V3 has fixed several issues in cost model and statistics information estimation. The fixes to the cost model are more adaptable to the evolution of the execution engine, making the execution plan more stable compared to previous versions.
+
+- **Enhanced Runtime Filter plan support**: On the basis of Join Runtime Filter, V3.0 has expanded the capability of the TopN Runtime Filter to achieve better performance in use cases that involve a TopN operator.
+
+- **Enriched optimization rule library**: Based on user feedback and internal testing results, we have introduced optimization rules such as Intersect Reorder to enrich the rule set of the optimizer.
+
+### 6-2 Self-adaptive Runtime Filter
+
+In previous versions, the generation of Runtime Filter relies on manual setting by users based on statistical information. However, inaccurate settings in certain cases could lead to performance instability.
+
+In V3.0, Doris implements a self-adaptive Runtime Filter calculation approach. It can estimate the Runtime Filter at runtime based on the data size with high accuracy, enabling better performance in use cases with large data volumes and high workloads. 
+
+### 6-3 Function performance optimization
+
+- V3.0 has improved the vectorized implementation of dozens of functions, enabling a performance improvement of over 50% for some commonly used functions.
+- V3.0 has also made extensive optimizations to the aggregation of nullable data types, enabling a 30% performance improvement.
+
+### 6-4 Blind test performance improvement
+
+Our blind tests on V3.0 and V2.1 show that the new version is 7.3% and 6.2% faster in TPC-DS and TPC-H benchmark tests, respectively.
+
+![Blind test performance improvement](/images/blind-test-performance-improvement.png)
+
+## 7. New features
+
+### 7-1 Java UDTF
+
+Version 3.0 has added support for Java UDTFs. The key operations are as follows:
+
+- Implementing a UDTF: Similar to a UDF, a UDTF requires the user to implement an `evaluate` method. Note that the return value of a UDTF function must be of the `Array` data type.
+
+  ```sql
+  public class UDTFStringTest {
+      public ArrayList<String> evaluate(String value, String separator) {
+          if (value == null || separator == null) {
+              return null;
+          } else {
+              return new ArrayList<>(Arrays.asList(value.split(separator)));
+          }
+      }
+  }
+  ```
+
+- Creating a UDTF: By default, two corresponding functions will be created - `java-utdf`and `java-utdf_outer`. The `_outer` suffix adds a single row of `NULL` data when the table function generates 0 rows of output.
+
+  ```sql
+  CREATE TABLES FUNCTION java-utdf(string, string) RETURNS array<string> PROPERTIES (
+      "file"="file:///pathTo/java-udaf.jar",
+      "symbol"="org.apache.doris.udf.demo.UDTFStringTest",
+      "always_nullable"="true",
+      "type"="JAVA_UDF"
+  );
+  ```
+
+:::info
+
+See doc: https://doris.apache.org/docs/3.0/query/udf/java-user-defined-function/#udtf-1
+
+:::
+
+### 7-2 Generated column
+
+A generated column is a special column whose value is calculated from the values of other columns rather than directly inserted or updated by the user. It supports pre-computing the results of expressions and storing them in the database, which is suitable for scenarios that require frequent queries or complex calculations.
+
+Results can be automatically calculated based on predefined expressions when data is imported or updated, and then stored persistently. In this way, during subsequent queries, the system can directly access these calculated results without performing complex calculations, thereby improving query performance.
+
+Generated columns are supported since V3.0. When creating a table, you can specify a column as generated column. A generated column automatically calculates values based on the defined expression when data is written. Generated columns allow for more complex expressions to be defined, but the value cannot be explicitly written or set.
+
+:::info
+
+See doc: https://doris.apache.org/docs/3.0/sql-manual/sql-statements/Data-Definition-Statements/Create/CREATE-TABLE-AND-GENERATED-COLUMN/
+
+:::
+
+## 8. Functional improvements
+
+### 8-1. Materialized view
+
+We have refactored the selection logic for materialized views and migrated it from the rule-based optimizer (RBO) to the cost-based optimizer (CBO). This aligns the selection logic with that of asynchronous materialized views. This functionality is enabled by default. If any issues are encountered, you can revert to the RBO mode using `set global enable_sync_mv_cost_based_rewrite = false`.
+
+### 8-2. Routine Load
+
+In previous versions, the Routine Load functionality faced some usability challenges, such as uneven task scheduling across BE nodes, untimely task scheduling, complex configuration requirements (the need to change multiple FE and BE settings for optimization), insufficient overall stability (where restarts or upgrades could frequently pause Routine Load jobs, requiring manual user intervention to resume).
+
+To address these issues, we have made extensive optimizations to the Routine Load feature:
+
+- **Resource scheduling**: We have improved the scheduling balance to make sure that tasks are more evenly distributed across BE nodes. Jobs that encounter unrepairable errors will be promptly paused to avoid wasting resources on futile scheduling attempts. Additionally, we have improved the timeliness of the scheduling process, which has enhanced the import performance of Routine Load.
+
+- **Parameter configuration**: Users in most environments no longer need to modify FE and BE configurations for optimization. An automatic adjustment mechanism with timeout parameter has been introduced to prevent tasks from constantly retrying when cluster pressure increases.
+
+- **Stability**: We have enhanced the robustness of Doris in various exceptional scenarios, such as FE failovers, BE rolling upgrades, and Kafka cluster anomalies, ensuring continuous stable operation. We have also optimized the Auto Resume mechanism, allowing Routine Load to automatically resume operation after faults are repaired, reducing the need for manual user intervention.
+
+## 9. Behavior changed
+
+- `cpu_resource_limit` will no longer be supported, and all types of resource isolation will be implemented through Workload Groups.
+
+- Please use JDK 17 for Apache Doris 3.0 and later versions. The recommended version being `jdk-17.0.10_linux-x64_bin.tar.gz`.
+
+## Try Apache Doris 3.0 now!
+
+Before the official release of version 3.0, the compute-storage decoupled mode of Apache Doris has undergone nearly two years of extensive testing and optimization in the production environments of hundreds of enterprises. Contributors from many tech giants have collaborated with the community to provide a significant number of test cases based on their real-world business needs. This has rigorously validated the usability and stability of version 3.0.
+
+We highly recommend users with compute-storage decoupling needs to download version 3.0 and experience it firsthand.
+
+Going forward, we will accelerate our release iteration cycle to deliver a more stable version experience for all users. Feel free to join us in the [Apache Doris community](https://join.slack.com/t/apachedoriscommunity/shared_invite/zt-2gmq5o30h-455W226d79zP3L96ZhXIoQ) and engage directly with the core developers.

+
+## Behavior Changes
+
+### Query Optimizer
+
+- Added the variable `use_max_length_of_varchar_in_ctas` to control the length behavior of VARCHAR type when executing `CREATE TABLE AS SELECT` (CTAS) operations.  [#37069](https://github.com/apache/doris/pull/37069)
+  
+  - This variable is set to true by default. 
+  
+  - When set to true, if the VARCHAR type column originates from a table, the derived length is used; otherwise, the maximum length is used. 
+  
+  - When set to false, the VARCHAR type will always use the derived length.
+
+- All data types will now be displayed in lowercase to maintain compatibility with MySQL format. [#38012](https://github.com/apache/doris/pull/38012)
+
+- Multiple query statements in the same query request must now be separated by semicolons. [#38670](https://github.com/apache/doris/pull/38670)
+
+### Query Execution
+
+- The default number of parallel tasks after shuffle operations in the cluster is set to 100, which will improve query stability and concurrent processing capability in large clusters. [#38196](https://github.com/apache/doris/pull/38196)
+
+### Storage
+
+- The default value of `trash_file_expire_time_sec` has been changed from 86400 seconds to 0 seconds, which means that if files are deleted by mistake and the FE trash is cleared, the data cannot be recovered.
+
+- The table attribute `enable_mow_delete_on_delete_predicate` (introduced in version 3.0.0) has been renamed to `enable_mow_light_delete`.
+
+- Explicit transactions are now prohibited from performing delete operations on tables with written data.
+
+- Heavy schema change operations are prohibited on tables with auto-increment fields.
+
+
+
+## New Features
+
+### Job Scheduling
+
+- Optimized the execution logic of internal scheduling jobs, decoupling the strong association between start time and immediate execution parameters. Now, tasks can be created with a specified start time or selected for immediate execution, without conflict, enhancing scheduling flexibility. [#36805](https://github.com/apache/doris/pull/36805)
+
+### Compute-Storage Decoupled
+
+- Supports dynamic modification of the upper limit for file cache usage. [#37484](https://github.com/apache/doris/pull/37484)
+
+- Recycler now supports object storage rate limiting and server-side rate limiting retry functionality. [#37663](https://github.com/apache/doris/pull/37663) [#37680](https://github.com/apache/doris/pull/37680)
+
+### Lakehouse
+
+- Added the session variable `serde_dialect` to set the output format for complex types. [#37039](https://github.com/apache/doris/pull/37039)
+
+- SQL interception now supports external tables.
+
+  - For more information, refer to the documentation on  [SQL Interception](https://doris.apache.org/docs/admin-manual/query-admin/sql-interception).
+
+- Insert overwrite now supports Iceberg tables. [#37191](https://github.com/apache/doris/pull/37191)
+
+### Asynchronous Materialized Views
+
+- Supports partition roll-up and build at the hourly level. [#37678](https://github.com/apache/doris/pull/37678)
+
+- Supports atomic replacement of asynchronous materialized view definition statements. [#36749](https://github.com/apache/doris/pull/36749)
+
+- Transparent rewriting now supports Insert statements. [#38115](https://github.com/apache/doris/pull/38115)
+
+- Transparent rewriting now supports the VARIANT type. [#37929](https://github.com/apache/doris/pull/37929)
+
+### Query Execution
+
+- The group concat function now supports DISTINCT and ORDER BY options. [#38744](https://github.com/apache/doris/pull/38744)
+
+### Semi-Structured Data Management
+
+- The ES Catalog now maps `nested` or `object` types in Elasticsearch to the JSON type in Doris. [#37101](https://github.com/apache/doris/pull/37101)
+
+- Added the `MULTI_MATCH` function, which supports matching keywords across multiple fields and can leverage inverted indexes to accelerate searches. [#37722](https://github.com/apache/doris/pull/37722)
+
+- Added the `explode_json_object` function, which can unfold objects in JSON data into multiple rows. [#36887](https://github.com/apache/doris/pull/36887)
+
+- Inverted indexes now support memtable advancement, requiring index construction only once during multi-replica writes, reducing CPU consumption and improving performance. [#35891](https://github.com/apache/doris/pull/35891)
+
+- Added `MATCH_PHRASE` support for positive slop, e.g., `msg MATCH_PHRASE 'a b 2+'` can match instances containing words a and b with a slop of no more than two, and a preceding b; regular slop without the final `+` does not guarantee this order. [#36356](https://github.com/apache/doris/pull/36356)
+
+### Other
+
+- Added the FE parameter `skip_audit_user_list`, where user operations specified in this configuration will not be recorded in the audit log. [#38310](https://github.com/apache/doris/pull/38310)
+
+  - For more information, refer to the documentation on [Audit Plugin](https://doris.apache.org/docs/admin-manual/audit-plugin/).
+

+
+- Optimized read failures caused by potential inconsistencies in the local file cache through backoff retries. [#38645](https://github.com/apache/doris/pull/38645)
+
+### Lakehouse
+
+- Optimized memory statistics for Parquet/ORC format read and write operations. [#37234](https://github.com/apache/doris/pull/37234)
+
+- Trino Connector Catalog now supports predicate pushdown. [#37874](https://github.com/apache/doris/pull/37874)
+
+- Added a session variable `enable_count_push_down_for_external_table` to control whether to enable `count(*)` pushdown optimization for external tables. [#37046](https://github.com/apache/doris/pull/37046)
+
+- Optimized the read logic for Hudi snapshot reads, returning an empty set when the snapshot is empty, consistent with Spark behavior. [#37702](https://github.com/apache/doris/pull/37702)
+
+- Improved the read performance of partition columns for Hive tables. [#37377](https://github.com/apache/doris/pull/37377)

+
+- Eliminated roll-up during transparent rewrite if the group key satisfies data uniqueness for better nested matching. [#38387](https://github.com/apache/doris/pull/38387)
+
+- Transparent rewrite now performs better aggregation elimination to improve the matching success rate of nested materialized views. [#36888](https://github.com/apache/doris/pull/36888)
+
+### MySQL Compatibility
+
+- Now correctly populates the database name, table name, and original name in the MySQL protocol result columns. [#38126](https://github.com/apache/doris/pull/38126)

+- Supported the hint format `/*+ func(value) */`. [#37720](https://github.com/apache/doris/pull/37720)
+
+### Query Optimizer
+
+- Significantly improved the plan speed for complex queries. [#38317](https://github.com/apache/doris/pull/38317)

+
+In version 1.1, we realized the full vectorization of the computing layer and storage layer, and officially enabled the vectorized execution engine as a stable function. All queries are executed by the vectorized execution engine by default, and the performance is 3-5 times higher than the previous version. It increases the ability to access the external tables of Apache Iceberg and supports federated query of data in Doris and Iceberg, and expands the analysis capabilities of Apache Doris on the data lake; on the basis of the original LZ4, the ZSTD compression algorithm is added , further improves the data compression rate; fixed many performance and stability problems in previous versions, greatly improving system stability. Downloading and using is recommended.
+
+## Upgrade Notes
+
+### The vectorized execution engine is enabled by default
+
+In version 1.0, we introduced the vectorized execution engine as an experimental feature and Users need to manually enable it when executing queries by configuring the session variables through `set batch_size = 4096` and `set enable_vectorized_engine = true` .
+
+In version 1.1, we officially fully enabled the vectorized execution engine as a stable function. The session variable `enable_vectorized_engine` is set to true by default. All queries are executed by default through the vectorized execution engine.
+
+### BE Binary File Renaming
+
+BE binary file has been renamed from palo_be to doris_be . Please pay attention to modifying the relevant scripts if you used to rely on process names for cluster management and other operations.
+
+### Segment storage format upgrade
+
+The storage format of earlier versions of Apache Doris was Segment V1. In version 0.12, we had implemented Segment V2 as a new storage format, which introduced Bitmap indexes, memory tables, page cache, dictionary compression, delayed materialization and many other features. Starting from version 0.13, the default storage format for newly created tables is Segment V2, while maintaining compatibility with the Segment V1 format.
+
+In order to ensure the maintainability of the code structure and reduce the additional learning and development costs caused by redundant historical codes, we have decided to no longer support the Segment v1 storage format from the next version. It is expected that this part of the code will be deleted in the Apache Doris 1.2 version.
+
+### Normal Upgrade
+
+For normal upgrade operations, you can perform rolling upgrades according to the cluster upgrade documentation on the official website.
+
+[https://doris.apache.org//docs/admin-manual/cluster-management/upgrade](https://doris.apache.org//docs/admin-manual/cluster-management/upgrade)
+
+## Features
+
+### Support random distribution of data [experimental]
+
+In some scenarios (such as log data analysis), users may not be able to find a suitable bucket key to avoid data skew, so the system needs to provide additional distribution methods to solve the problem.
+
+Therefore, when creating a table you can set `DISTRIBUTED BY random BUCKETS number`to use random distribution, the data will be randomly written to a single tablet when importing to reduce the data fanout during the loading process. And reduce resource overhead and improve system stability.
+
+### Support for creating Iceberg external tables[experimental]
+
+Iceberg external tables provide Apache Doris with direct access to data stored in Iceberg. Through Iceberg external tables, federated queries on data stored in local storage and Iceberg can be implemented, which saves tedious data loading work, simplifies the system architecture for data analysis, and performs more complex analysis operations.
+
+In version 1.1, Apache Doris supports creating Iceberg external tables and querying data, and supports automatic synchronization of all table schemas in the Iceberg database through the REFRESH command.
+
+### Added ZSTD compression algorithm
+
+At present, the data compression method in Apache Doris is uniformly specified by the system, and the default is LZ4. For some scenarios that are sensitive to data storage costs, the original data compression ratio requirements cannot be met.
+
+In version 1.1, users can set "compression"="zstd" in the table properties to specify the compression method as ZSTD when creating a table. In the 25GB 110 million lines of text log test data, the highest compression rate is nearly 10 times, which is 53% higher than the original compression rate, and the speed of reading data from disk and decompressing it is increased by 30%.
+
+## Improvements
+
+### More comprehensive vectorization support
+
+In version 1.1, we implemented full vectorization of the compute and storage layers, including:
+
+Implemented vectorization of all built-in functions
+
+The storage layer implements vectorization and supports dictionary optimization for low-cardinality string columns
+
+Optimized and resolved numerous performance and stability issues with the vectorization engine.
+
+We tested the performance of Apache Doris version 1.1 and version 0.15 on the SSB and TPC-H standard test datasets:
+
+On all 13 SQLs in the SSB test data set, version 1.1 is better than version 0.15, and the overall performance is improved by about 3 times, which solves the problem of performance degradation in some scenarios in version 1.0;
+
+On all 22 SQLs in the TPC-H test data set, version 1.1 is better than version 0.15, the overall performance is improved by about 4.5 times, and the performance of some scenarios is improved by more than ten times;

+
+### Compaction logic optimization and real-time guarantee
+
+In Apache Doris, each commit will generate a data version. In high concurrent write scenarios, -235 errors are prone to occur due to too many data versions and untimely compaction, and query performance will also decrease accordingly.
+
+In version 1.1, we introduced QuickCompaction, which will actively trigger compaction when the data version increases. At the same time, by improving the ability to scan fragment metadata, it can quickly find fragments with too many data versions and trigger compaction. Through active triggering and passive scanning, the real-time problem of data merging is completely solved.
+
+At the same time, for high-frequency small file cumulative compaction, the scheduling and isolation of compaction tasks is implemented to prevent the heavyweight base compaction from affecting the merging of new data.
+
+Finally, for the merging of small files, the strategy of merging small files is optimized, and the method of gradient merging is adopted. Each time the files participating in the merging belong to the same data magnitude, it prevents versions with large differences in size from merging, and gradually merges hierarchically. , reducing the number of times a single file participates in merging, which can greatly save the CPU consumption of the system.
+
+When the data upstream maintains a write frequency of 10w per second (20 concurrent write tasks, 5000 rows per job, and checkpoint interval of 1s), version 1.1 behaves as follows:
+
+-   Quick data consolidation: Tablet version remains below 50 and compaction score is stable. Compared with the -235 problem that frequently occurred during high concurrent writing in the previous version, the compaction merge efficiency has been improved by more than 10 times.
+
+-   Significantly reduced CPU resource consumption: The strategy has been optimized for small file Compaction. In the above scenario of high concurrent writing, CPU resource consumption is reduced by 25%;
+
+-   Stable query time consumption: The overall orderliness of data is improved, and the fluctuation of query time consumption is greatly reduced. The query time consumption during high concurrent writing is the same as that of only querying, and the query performance is improved by 3-4 times compared with the previous version.
+
+### Read efficiency optimization for Parquet and ORC files
+
+By adjusting arrow parameters, arrow's multi-threaded read capability is used to speed up Arrow's reading of each row_group, and it is modified to SPSC model to reduce the cost of waiting for the network through prefetching. After optimization, the performance of Parquet file import is improved by 4 to 5 times.
+
+### Safer metadata Checkpoint
+
+By double-checking the image files generated after the metadata checkpoint and retaining the function of historical image files, the problem of metadata corruption caused by image file errors is solved.
+
+## Bugfix
+
+### Fix the problem that the data cannot be queried due to the missing data version.(Serious)
+
+This issue was introduced in version 1.0 and may result in the loss of data versions for multiple replicas.
+
+### Fix the problem that the resource isolation is invalid for the resource usage limit of loading tasks (Moderate)
+
+In 1.1, the broker load and routine load will use Backends with specified resource tags to do the load.
+
+### Use HTTP BRPC to transfer network data packets over 2GB (Moderate)
+
+In the previous version, when the data transmitted between Backends through BRPC exceeded 2GB,
+it may cause data transmission errors.
+
+## Others
+
+### Disabling Mini Load
+
+The `/_load` interface is disabled by default, please use `the /_stream_load` interface uniformly.
+Of course, you can re-enable it by turning off the FE configuration item `disable_mini_load`.
+
+The Mini Load interface will be completely removed in version 1.2.
+
+### Completely disable the SegmentV1 storage format
+
+Data in SegmentV1 format is no longer allowed to be created. Existing data can continue to be accessed normally.
+You can use the `ADMIN SHOW TABLET STORAGE FORMAT` statement to check whether the data in SegmentV1 format
+still exists in the cluster. And convert to SegmentV2 through the data conversion command
+
+Access to SegmentV1 data will no longer be supported in version 1.2.
+
+### Limit the maximum length of String type
+
+In previous versions, String types were allowed a maximum length of 2GB.
+In version 1.1, we will limit the maximum length of the string type to 1MB. Strings longer than this length cannot be written anymore.
+At the same time, using the String type as a partitioning or bucketing column of a table is no longer supported.
+
+The String type that has been written can be accessed normally.
+
+### Fix fastjson related vulnerabilities
+
+Update to Canal version to fix fastjson security vulnerability.
+
+### Added `ADMIN DIAGNOSE TABLET` command
+
+Used to quickly diagnose problems with the specified tablet.

+
+## Features
+
+### Support ODBC Sink in Vectorized Engine.
+
+This feature is enabled in non-vectorized engine but it is missed in vectorized engine in 1.1. So that we add back this feature in 1.1.1.
+
+### Simple Memtracker for Vectorized Engine.
+
+There is no memtracker in BE for vectorized engine in 1.1, so that the memory is out of control and cause OOM. In 1.1.1, a simple memtracker is added to BE and could control the memory and cancel the query when memory exceeded.
+
+## Improvements
+
+### Cache decompressed data in page cache.
+
+Some data is compressed using bitshuffle and it costs a lot of time to decompress it during query. In 1.1.1, doris will decompress the data that encoded by bitshuffle to accelerate query and we find it could reduce 30% latency for some query in ssb-flat.
+
+## Bug Fix
+
+### Fix the problem that could not do rolling upgrade from 1.0.(Serious)
+
+This issue was introduced in version 1.1 and may cause BE core when upgrade BE but not upgrade FE.
+
+If you encounter this problem, you can try to fix it with [#10833](https://github.com/apache/doris/pull/10833).
+
+### Fix the problem that some query not fall back to non-vectorized engine, and BE will core.
+
+Currently, vectorized engine could not deal with all sql queries and some queries (like left outer join) will use non-vectorized engine to run. But there are some cases not covered in 1.1. And it will cause be crash.
+
+### Compaction not work correctly and cause -235 Error.
+
+One rowset multi segments in uniq key compaction, segments rows will be merged in generic_iterator but merged_rows not increased. Compaction will failed in check_correctness, and make a tablet with too much versions which lead to -235 load error.
+
+### Some segment fault cases during query.

+
+# Upgrade Notes
+
+PageCache and ChunkAllocator are disabled by default to reduce memory usage and can be re-enabled by modifying the configuration items `disable_storage_page_cache` and `chunk_reserved_bytes_limit`.
+
+Storage Page Cache and Chunk Allocator cache user data chunks and memory preallocation, respectively.
+
+These two functions take up a certain percentage of memory and are not freed. This part of memory cannot be flexibly allocated, which may lead to insufficient memory for other tasks in some scenarios, affecting system stability and availability. Therefore, we disabled these two features by default in version 1.1.3.
+
+However, in some latency-sensitive reporting scenarios, turning off this feature may lead to increased query latency. If you are worried about the impact of this feature on your business after upgrade, you can add the following parameters to be.conf to keep the same behavior as the previous version.
+
+```
+disable_storage_page_cache=false
+chunk_reserved_bytes_limit=10%
+```
+
+* ``disable_storage_page_cache``: Whether to disable Storage Page Cache. version 1.1.2 (inclusive), the default is false, i.e., on. version 1.1.3 defaults to true, i.e., off.
+* `chunk_reserved_bytes_limit`: Chunk allocator reserved memory size. 1.1.2 (and earlier), the default is 10% of the overall memory. 1.1.3 version default is 209715200 (200MB).

+
+In this release, Doris Team has fixed about 36 issues or performance improvement since 1.1.4. This release is a bugfix release on 1.1 and all users are encouraged to upgrade to this release.
+
+# Behavior Changes
+
+When alias name is same as the original column name like "select year(birthday) as birthday" and use it in group by, order by , having clause, doris's behavior is different from MySQL in the past. In this release, we make it follow MySQL's behavior. Group by and having clause will use original column at first and order by will use alias first. It maybe a litter confuse here so there is a simple advice here, you'd better not use an alias the same as original column name.

+# Feature
+## Highlight
+
+1. Full Vectorizied-Engine support, greatly improved performance
+
+	In the standard ssb-100-flat benchmark, the performance of 1.2 is 2 times faster than that of 1.1; in complex TPCH 100 benchmark, the performance of 1.2 is 3 times faster than that of 1.1.
+
+2. Merge-on-Write Unique Key
+
+	Support Merge-On-Write on Unique Key Model. This mode marks the data that needs to be deleted or updated when the data is written, thereby avoiding the overhead of Merge-On-Read when querying, and greatly improving the reading efficiency on the updateable data model.
+
+3. Multi Catalog
+
+	The multi-catalog feature provides Doris with the ability to quickly access external data sources for access. Users can connect to external data sources through the `CREATE CATALOG` command. Doris will automatically map the library and table information of external data sources. After that, users can access the data in these external data sources just like accessing ordinary tables. It avoids the complicated operation that the user needs to manually establish external mapping for each table.
+    
+    Currently this feature supports the following data sources:
+    
+    1. Hive Metastore: You can access data tables including Hive, Iceberg, and Hudi. It can also be connected to data sources compatible with Hive Metastore, such as Alibaba Cloud's DataLake Formation. Supports data access on both HDFS and object storage.
+    2. Elasticsearch: Access ES data sources.
+    3. JDBC: Access MySQL through the JDBC protocol.
+    
+    Documentation: https://doris.apache.org//docs/dev/lakehouse/multi-catalog)
+
+    > Note: The corresponding permission level will also be changed automatically, see the "Upgrade Notes" section for details.
+    
+4. Light table structure changes
+
+In the new version, it is no longer necessary to change the data file synchronously for the operation of adding and subtracting columns to the data table, and only need to update the metadata in FE, thus realizing the millisecond-level Schema Change operation. Through this function, the DDL synchronization capability of upstream CDC data can be realized. For example, users can use Flink CDC to realize DML and DDL synchronization from upstream database to Doris.
+
+Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Definition-Statements/Create/CREATE-TABLE
+
+When creating a table, set `"light_schema_change"="true"` in properties.
+
+5. JDBC facade
+
+	Users can connect to external data sources through JDBC. Currently supported:
+
+	  - MySQL
+	  - PostgreSQL
+	  - Oracle
+	  - SQL Server
+	  - Clickhouse
+
+	Documentation: [https://doris.apache.org/en/docs/dev/lakehouse/multi-catalog/jdbc](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc/)
+
+	> Note: The ODBC feature will be removed in a later version, please try to switch to the JDBC.
+
+6. JAVA UDF
+
+	Supports writing UDF/UDAF in Java, which is convenient for users to use custom functions in the Java ecosystem. At the same time, through technologies such as off-heap memory and Zero Copy, the efficiency of cross-language data access has been greatly improved.
+
+	Document: https://doris.apache.org//docs/dev/ecosystem/udf/java-user-defined-function
+
+	Example: https://github.com/apache/doris/tree/master/samples/doris-demo
+	
+7. Remote UDF
+
+	Supports accessing remote user-defined function services through RPC, thus completely eliminating language restrictions for users to write UDFs. Users can use any programming language to implement custom functions to complete complex data analysis work.
+
+	Documentation: https://doris.apache.org//docs/ecosystem/udf/remote-user-defined-function
+
+	Example: https://github.com/apache/doris/tree/master/samples/doris-demo
+        
+8. More data types support
+
+	- Array type
+
+		Array types are supported. It also supports nested array types. In some scenarios such as user portraits and tags, the Array type can be used to better adapt to business scenarios. At the same time, in the new version, we have also implemented a large number of data-related functions to better support the application of data types in actual scenarios.
+
+	Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Types/ARRAY
+
+	Related functions: https://doris.apache.org//docs/dev/sql-manual/sql-functions/array-functions/array_max
+        
+	- Jsonb type
+
+		Support binary Json data type: Jsonb. This type provides a more compact json encoding format, and at the same time provides data access in the encoding format. Compared with json data stored in strings, it is several times newer and can be improved.
+
+	Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Types/JSONB
+
+	Related functions: https://doris.apache.org//docs/dev/sql-manual/sql-functions/json-functions/jsonb_parse
+          
+	- Date V2
+	
+		Sphere of influence:
+
+		1. The user needs to specify datev2 and datetimev2 when creating the table, and the date and datetime of the original table will not be affected.
+		2. When datev2 and datetimev2 are calculated with the original date and datetime (for example, equivalent connection), the original type will be cast into a new type for calculation
+		3. The example is in the documentation
+
+		Documentation: https://doris.apache.org/docs/1.2/sql-manual/sql-reference/Data-Types/DATEV2
+	 
+	 
+## More
+
+1. A new memory management framework
+
+	Documentation: https://doris.apache.org//docs/dev/admin-manual/maint-monitor/memory-management/memory-tracker
+
+2. Table Valued Function
+
+	Doris implements a set of Table Valued Function (TVF). TVF can be regarded as an ordinary table, which can appear in all places where "table" can appear in SQL.
+
+	For example, we can use S3 TVF to implement data import on object storage:
+
+	```
+	insert into tbl select * from s3("s3://bucket/file.*", "ak" = "xx", "sk" = "xxx") where c1 > 2;
+	```
+
+	Or directly query data files on HDFS:
+	
+	```
+	insert into tbl select * from hdfs("hdfs://bucket/file.*") where c1 > 2;
+	```
+	
+	TVF can help users make full use of the rich expressiveness of SQL and flexibly process various data.

+# Upgrade Notice
+
+## Known Issues
+
+- Use JDK11 will cause BE crash, please use JDK8 instead.
+
+## Behavior Changed
+
+- Permission level changes
+
+	Because the catalog level is introduced, the corresponding user permission level will also be changed automatically. The rules are as follows:
+	
+	- GlobalPrivs and ResourcePrivs remain unchanged
+	- Added CatalogPrivs level.
+	- The original DatabasePrivs level is added with the internal prefix (indicating the db in the internal catalog)
+	- Add the internal prefix to the original TablePrivs level (representing tbl in the internal catalog)
+
+- In GroupBy and Having clauses, match on column names in preference to aliases. (#14408)
+
+- Creating columns starting with `mv_` is no longer supported. `mv_` is a reserved keyword in materialized views (#14361)
+
+- Removed the default limit of 65535 rows added by the order by statement, and added the session variable `default_order_by_limit` to configure this limit. (#12478)
+
+- In the table generated by "Create Table As Select", all string columns use the string type uniformly, and no longer distinguish varchar/char/string (#14382)
+
+- In the audit log, remove the word `default_cluster` before the db and user names. (#13499) (#11408)
+
+- Add sql digest field in audit log (#8919)
+
+- The union clause always changes the order by logic. In the new version, the order by clause will be executed after the union is executed, unless explicitly associated by parentheses. (#9745)
+
+- During the decommission operation, the tablet in the recycle bin will be ignored to ensure that the decomission can be completed. (#14028)
+
+- The returned result of Decimal will be displayed according to the precision declared in the original column, or according to the precision specified in the cast function. (#13437)
+
+- Changed column name length limit from 64 to 256 (#14671)
+
+- Changes to FE configuration items
+
+  - The `enable_vectorized_load` parameter is enabled by default. (#11833)
+
+  - Increased `create_table_timeout` value. The default timeout for table creation operations will be increased. (#13520)
+
+  - Modify `stream_load_default_timeout_second` default value to 3 days.
+
+  - Modify the default value of `alter_table_timeout_second` to one month.
+
+  - Increase the parameter `max_replica_count_when_schema_change` to limit the number of replicas involved in the alter job, the default is 100000. (#12850)
+
+  - Add `disable_iceberg_hudi_table`. The iceberg and hudi appearances are disabled by default, and the multi catalog function is recommended. (#13932)
+
+- Changes to BE configuration items
+
+  - Removed `disable_stream_load_2pc` parameter. 2PC's stream load can be used directly. (#13520)
+
+  - Modify `tablet_rowset_stale_sweep_time_sec` from 1800 seconds to 300 seconds.
+
+  - Redesigned configuration item name about compaction (#13495)
+
+  - Revisited parameter about memory optimization (#13781)
+
+- Session variable changes
+
+   - Modify the variable `enable_insert_strict` to true by default. This will cause some insert operations that could be executed before, but inserted illegal values, to no longer be executed. (11866)
+
+   - Modified variable `enable_local_exchange` to default to true (#13292)
+
+   - Default data transmission via lz4 compression, controlled by variable `fragment_transmission_compression_codec` (#11955)
+
+   - Add `skip_storage_engine_merge` variable for debugging unique or agg model data (#11952)
+    
+     Documentation: https://doris.apache.org//docs/dev/advanced/variables
+
+- The BE startup script will check whether the value is greater than 200W through `/proc/sys/vm/max_map_count`. Otherwise, the startup fails. (#11052)
+
+- Removed mini load interface (#10520)
+
+- FE Metadata Version
+
+	FE Meta Version changed from 107 to 114, and cannot be rolled back after upgrading.
+	
+## During Upgrade
+
+1. Upgrade preparation
+  
+   - Need to replace: lib, bin directory (start/stop scripts have been modified)
+  
+   - BE also needs to configure JAVA_HOME, and already supports JDBC Table and Java UDF.
+  
+   - The default JVM Xmx parameter in fe.conf is changed to 8GB.
+
+2. Possible errors during the upgrade process
+  
+   - The repeat function cannot be used and an error is reported: `vectorized repeat function cannot be executed`, you can turn off the vectorized execution engine before upgrading. (#13868)
+  
+   - schema change fails with error: `desc_tbl is not set. Maybe the FE version is not equal to the BE` (#13822)
+  
+   - Vectorized hash join cannot be used and an error will be reported. `vectorized hash join cannot be executed`. You can turn off the vectorized execution engine before upgrading. (#13753)
+
+	The above errors will return to normal after a full upgrade.
+	
+## Performance Impact
+
+- By default, JeMalloc is used as the memory allocator of the new version BE, replacing TcMalloc (#13367)
+
+- The batch size in the tablet sink is modified to be at least 8K. (#13912)
+
+- Disable chunk allocator by default (#13285)
+
+## Api change

+
+- In `SHOW CREATE TABLE`, the content of comment is changed from double quotes to single quotes (#10327)
+
+- Support ordinary users to obtain query profile through http command. (#14016)
+Documentation: https://doris.apache.org//docs/dev/admin-manual/http-actions/fe/manager/query-profile-action
+
+- Optimized the way to specify the sequence column, you can directly specify the column name. (#13872)
+Documentation: https://doris.apache.org//docs/dev/data-operate/update-delete/sequence-column-manual
+
+- Increase the space usage of remote storage in the results returned by `show backends` and `show tablets` (#11450)

+# Improvement
+
+### Supports new type DecimalV3
+
+DecimalV3, which supports higher precision and better performance, has the following advantages over past versions.
+
+- Larger representable range, the range of values are significantly expanded, and the valid number range [1,38].
+
+- Higher performance, adaptive adjustment of the storage space occupied according to different precision.
+
+- More complete precision derivation support, for different expressions, different precision derivation rules are applied to the accuracy of the result.
+
+[DecimalV3](https://doris.apache.org/docs/dev/sql-manual/sql-reference/Data-Types/DECIMALV3/)
+
+### Support Iceberg V2
+
+Support Iceberg V2 (only Position Delete is supported, Equality Delete will be supported in subsequent versions).
+
+Tables in Iceberg V2 format can be accessed through the Multi-Catalog feature.
+
+### Support OR condition to IN
+
+Support converting  OR condition to IN condition, which can improve the execution efficiency in some scenarios.[#15437](https://github.com/apache/doris/pull/15437) [#12872](https://github.com/apache/doris/pull/12872)
+
+### Optimize the import and query performance of JSONB type

+
+# Upgrade Notice
+
+### Known Issues
+
+- Do not use JDK11 as the runtime JDK of BE, it will cause BE Crash.
+- The reading performance of the csv format in this version has declined, which will affect the import and reading efficiency of the csv format. We will fix it as soon as possible in the next three-digit version
+
+### Behavior Changed
+
+- The default value of the BE configuration item `high_priority_flush_thread_num_per_store` is changed from 1 to 6, to improve the write efficiency of Routine Load. (https://github.com/apache/doris/pull/14775)
+
+- The default value of the FE configuration item `enable_new_load_scan_node` is changed to true. Import tasks will be performed using the new File Scan Node. No impact on users.[#14808](https://github.com/apache/doris/pull/14808)
+
+- Delete the FE configuration item `enable_multi_catalog`. The Multi-Catalog function is enabled by default.
+
+- The vectorized execution engine is forced to be enabled by default.[#15213](https://github.com/apache/doris/pull/15213)
+
+The session variable enable_vectorized_engine will no longer take effect. Enabled by default.
+
+To make it valid again, set the FE configuration item `disable_enable_vectorized_engine` to false, and restart FE to make `enable_vectorized_engine` valid again.

+# Behavior Changed
+
+- For `DateV2`/`DatetimeV2` and `DecimalV3` type, in the results of `DESCRIBLE` and `SHOW CREATE TABLE` statements, they will no longer be displayed as `DateV2`/`DatetimeV2` or `DecimalV3`, but directly displayed as `Date`/`Datetime` or `Decimal`.
+
+	- This change is for compatibility with some BI tools. If you want to see the actual type of the column, you can check it with the `DESCRIBE ALL` statement.
+
+- When querying tables in the `information_schema` database, the meta information(database, table, column, etc.) in the external catalog is no longer returned by default.
+
+	- This change avoids the problem that the `information_schema` database cannot be queried due to the connection problem of some external catalog, so as to solve the problem of using some BI tools with Doris. It can be controlled by the FE configuration  `infodb_support_ext_catalog`, and the default value is `false`, that is, the meta information of external catalog will not be returned.
+
+# Improvement
+
+### JDBC Catalog
+
+- Supports connecting to Trino/Presto via JDBC Catalog
+
+​        Refer to: [https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino)

+
+### Spark Load 
+
+- Spark Load supports Resource Manager HA related configuration
+
+​        Refer to: https://github.com/apache/doris/pull/15000
+
+## Bug Fixes
+
+- Fixed several connectivity issues with Hive Catalog.

+
+In version 1.2.5, the Doris team has fixed nearly 210 issues or performance improvements since the release of version 1.2.4. At the same time, version 1.2.5 is also an iterative version of version 1.2.4, which has higher stability. It is recommended that all users upgrade to this version.
+
+# Behavior Changed
+
+- The `start_be.sh` script will check that the maximum number of file handles in the system must be greater than or equal to 65536, otherwise the startup will fail.
+
+- The BE configuration item `enable_quick_compaction` is set to true by default. The Quick Compaction is enabled by default. This feature is used to optimize the problem of small files in the case of large batch import.
+
+- After modifying the dynamic partition attribute of the table, it will no longer take effect immediately, but wait for the next task scheduling of the dynamic partition table to avoid some deadlock problems.
+
+# Improvement
+
+- Optimize the use of bthread and pthread to reduce the RPC blocking problem during the query process.
+
+- A button to download Profile is added to the Profile page of the FE web UI.
+
+- Added FE configuration `recover_with_skip_missing_version`, which is used to query to skip the problematic replica under certain failure conditions.
+
+- The row-level permission function supports external Catalog.
+
+- Hive Catalog supports automatic refreshing of kerberos tickets on the BE side without manual refreshing.
+
+- JDBC Catalog supports tables under the MySQL/ClickHouse system database (`information_schema`).
+
+# Bug Fixes
+
+- Fixed the problem of incorrect query results caused by low-cardinality column optimization
+
+- Fixed several authentication and compatibility issues accessing HDFS.
+
+- Fixed several issues with float/double and decimal types.
+
+- Fixed several issues with date/datetimev2 types.

+Dear community, we are pleased to share with you the official release of Apache Doris 2.1.0, now available for download and use as of March 8th. This latest version marks a significant milestone in our journey towards enhancing data analysis capabilities, particularly for handling massive and complex datasets.
+
+With Doris 2.1.0, our primary focus has been on optimizing analysis performance, and the results speak for themselves. We have achieved an impressive performance improvement of over 100% on the TPC-DS 1TB test dataset, making Apache Doris more capable of challenging real-world business scenarios.
+
+- **Quick Download:** [https://doris.apache.org/download/](https://doris.apache.org/download/)
+
+- **GitHub：** [https://github.com/apache/doris/releases](https://github.com/apache/doris/releases)
+
+
+## Performance improvement
+
+### Smarter optimizer
+
+On the basis of V2.0, the query optimizer in Doris V2.1 comes with enhanced statistics-based inference and enumeration framework. We have upgraded the cost model and expanded the optimization rules to serve the needs of more use cases
+
+### Better heuristic optimization
+
+For data analytics at scale or data lake scenarios, Doris V2.1 provides better heuristic query plans. Meanwhile, the RuntimeFilter is more self-adaptive to enable higher performance even without statistical information.
+
+### Parallel adaptive scan
+
+Doris V2.1 has adopted parallel adaptive scan to optimize scan I/O and thus improve query performance. It can avoid the negative impact of unreasonable numbers of buckets. (This feature is currently available on the Duplicate Key model and Merge-on-Write Unique Key model.)
+
+### Local shuffle
+
+We have introduced Local Shuffle to prevent uneven data distribution. Benchmark tests show that Local Shuffle in combination with Parallel Adaptive Scan can guarantee fast query performance in spite of unreasonable bucket number settings upon table creation.
+
+### Faster INSERT INTO SELECT
+
+To further improve the performance of INSERT INTO SELECT, which is a frequent operation in ETL, we have moved forward the MemTable execution-wise to reduce data ingestion overheads. Tests show that this can double the data ingestion speed in most cases compared to V2.0.
+Improved data lake analytics capabilities
+
+## Data lake analytic performance
+
+### TPC-DS Benchmark
+
+According to TPC-DS benchmark tests (1TB) of Doris V2.1 against Trino,
+
+- Without caching, the total execution time of Doris is 56% of that of Trino V435. (717s VS 1296s)
+- Enabling file cache can further increase the overall performance of Doris by 2.2 times. (323s)
+  This is achieved by a series of optimizations in I/O, parquet/ORC file reading, predicate pushdown, caching, and scan task scheduling, etc.
+
+### SQL dialects compatibility
+
+To facilitate migration to Doris and increase its compatibility with other DBMS, we have enabled SQL dialect conversion in V2.1. ([read more](../../lakehouse/sql-dialect)) For example, by set sql_dialect = "trino" in Doris, you can use the Trino SQL dialect as you're used to, without modifying your current business logic, and Doris will execute the corresponding queries for you. Tests in user production environment show that Doris V2.1 is compatible with 99% of Trino SQL.
+
+### Arrow Flight SQL protocol
+
+As a column-oriented database compatible with MySQL 8.0 protocol, Doris V2.1 now supports the Arrow Flight SQL protocol as well so users can have fast access to Doris data via Pandas/Numpy without data serialization and deserialization. For most common data types, the Arrow Flight protocol enables tens of times faster performance than the MySQL protocol.
+
+## Asynchronous materialized view
+
+V2.1 allows creating a materialized view based on multiple tables. This feature currently supports:
+
+- Transparent rewriting: supports transparent rewriting of common operators including Select, Where, Join, Group By, and Aggregation.
+- Auto refresh: supports regular refresh, manual refresh, full refresh, incremental refresh, and partition-based refresh.
+- Materialized view of external tables: supports materialized views based on external data tables such as those on Hive, Hudi, and Iceberg; supported synchronizing data from data lakes into Doris internal tables via materialized views.
+- Direct query on materialized views: Materialized views can be regarded as the result set after ETL. In this sense, materialized views are data tables, so users can conduct queries on them directly.
+
+## Enhanced storage
+
+### Auto-increment column
+
+V2.1 supports auto-increment columns, which can ensure data uniqueness of each row. This lays the foundation for efficient dictionary encoding and query pagination. For example, for precise UV calculation and customer grouping, users often apply the bitmap type in Doris, the process of which entails dictionary encoding. With V2.1, users can first create a dictionary table using the auto-increment column, and then simply load user data into it.
+
+### Auto partition
+
+To further release burden on operation and maintenance, V2.1 allows auto data partitioning. Upon data ingestion, it detects whether a partition exists for the data based on the partitioning column. If not, it automatically creates one and starts data ingestion.
+
+### High-concurrency real-time data ingestion
+
+For data writing, a back pressure mechanism is in place to avoid execessive data versions, so as to reduce resource consumption by data version merging. In addition, V2.1 supports group commit ([read more](../../data-operate/import/import-way/group-commit-manual)), which means to accumulate multiple writing and commit them as one. Benchmark tests on group commit with JDBC ingestion and the Stream Load method present great results.
+
+## Semi-structured data analysis
+
+### A new data type: Variant
+
+V2.1 supports a new data type named Variant. It can accommodate semi-structured data such as JSON as well as compound data types that contain integers, strings, booleans, etcs. Users don't have to pre-define the exact data types for a Variant column in the table schema. The Variant type is handy when processing nested data structures.
+You can include Variant columns and static columns with pre-defined data types in the same table. This will provide you with more flexibility in storage and queries.
+Tests with ClickBench datasets prove that data in Variant columns takes up the same storage space as data in static columns, which is half of that in JSON format. In terms of query performance, the Variant type enables 8 times higher query speed than JSON in hot runs and even more in cold runs.
+
+### IP types
+
+Doris V2.1 provides native support for IPv4 and IPv6. It stores IP data in binary format, which cuts down storage space usage by 60% compared to IP string in plain texts. Along with these IP types, we have added over 20 functions for IP data processing.
+
+### More powerful functions for compound data types
+
+- explode_map: supports exploding rows into columns for the Map data type.
+- Supports the STRUCT data type in the IN predicates
+
+## Workload Management
+
+### Hard isolation of resources
+
+On the basis of the Workload Group mechanism, which imposes a soft limit on the resources that a workload group can use, Doris 2.1 introduces a hard limit on CPU resource consumption for workload groups as a way to ensure higher stability in query performance.
+
+### TopSQL
+
+V2.1 allows users to check the most resource-consuming SQL queries in the runtime. This can be a big help when handling cluster load spike caused by unexpected large queries.
+
+
+## Others
+
+### Decimal 256
+
+For users in the financial sector or high-end manufacturing, V2.1 supports a high-precision data type: Decimal, which supports up to 76 significant digits (an experimental feature, please set enable_decimal256=true.)
+
+### Job scheduler
+
+V2.1 provides a good option for regular task scheduling: Doris Job Scheduler. It can trigger the pre-defined operations on schedule or at fixed intervals. The Doris Job Scheduler is accurate to the second. It provides consistency guarantee for data writing, high efficiency and flexibility, high-performance processing queues, retraceable scheduling records, and high availability of jobs.
+
+### Support Docker fast start to experience the new version
+
+Starting from version 2.1.0, we will provide a separate Docker Image to support the rapid creation of a 1FE, 1BE Docker container to experience the new version of Doris. The container will complete the initialization of FE and BE, BE registration and other steps by default. After creating the container, it can directly access and use the Doris cluster about 1 [minute.In](http://minute.in/) this image version, the default `max_map_count`, `ulimit`, `Swap` and other hard limits are removed. It supports X64 (avx2) machines and ARM machines for deployment. The default open ports are 8000, 8030, 8040, 9030.If you need to experience the Broker component, you can add the environment variable `--env BROKER=true` at startup to start the Broker process synchronously. After startup, it will automatically complete the registration. The Broker name is `test`.
+
+Please note that this version is only suitable for quick experience and functional testing, not for production environment!
+
+## Behavior changed
+
+- The default data model is the Merge-on-Write Unique Key model. enable_unique_key_merge_on_write will be included as a default setting when a table is created in the Unique Key model.
+- As inverted index has proven to be more performant than bitmap index, V2.1 stops supporting bitmap index. Existing bitmap indexes will remain effective but new creation is not allowed. We will remove bitmap index-related code in the future.
+- cpu_resource_limit is no longer supported. It is to put a limit on the number of scanner threads on Doris BE. Since the workload group mechanism also supports such settings, the already configured cpu_resource_limit will be invalid.
+- The default value of enable_segcompaction is true. This means Doris supports compaction of multiple segments in the same rowset.
+- Audit log plug-in
+  - Since V2.1.0, Doris has a built-in audit log plug-in. Users can simply enable or disable it by setting the enable_audit_plugin parameter.
+  - If you have already installed your own audit log plug-in, you can either continue using it after upgrading to Doris V2.1, or uninstall it and use the one in Doris. Please note that the audit log table will be relocated after switching plug-in.
+  - For more details, please see the [docs](../../admin-manual/audit-plugin).

+
+Apache Doris 2.1.3 was officially released on May 21, 2024. This version has updated several improvements, including writing data back to Hive, materialized view, permission management and bug fixes. It further enhances the performance and stability of the system.
+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+
+
+## Feature Enhancements
+
+**1. Support writing back data to hive tables via Hive Catalog**
+
+Starting from version 2.1.3, Apache Doris supports DDL and DML operations on Hive. Users can directly create libraries and tables in Hive through Apache Doris and write data to Hive tables by executing `INSERT INTO` statements. This feature allows users to perform complete data query and write operations on Hive through Apache Doris, further simplifying the integrated lakehouse architecture.
+
+Please refer: [https://doris.apache.org/docs/lakehouse/datalake-building/hive-build/](https://doris.apache.org/docs/lakehouse/datalake-building/hive-build/)
+
+**2. Support building new asynchronous materialized views on top of existing ones**
+
+Users can create new asynchronous materialized views on top of existing ones, directly reusing pre-computed intermediate results for data processing. This simplifies complex aggregation and computation operations, reducing resource consumption and maintenance costs while further accelerating query performance and improving data availability. [#32984](https://github.com/apache/doris/pull/32984)
+
+**3. Support rewriting through nested materialized views**
+
+Materialized View (MV) is a database object used to store query results. Now, Apache Doris supports rewriting through nested materialized views, which helps optimize query performance. [#33362](https://github.com/apache/doris/pull/33362)
+
+**4. New `SHOW VIEWS` statement**
+
+The `SHOW VIEWS` statement can be used to query views in the database, facilitating better management and understanding of view objects in the database. [#32358](https://github.com/apache/doris/pull/32358)
+
+**5. Workload Group supports binding to specific BE nodes**
+
+Workload Group can be bound to specific BE nodes, enabling more refined control over query execution to optimize resource usage and improve performance. [#32874](https://github.com/apache/doris/pull/32874)
+
+**6. Broker Load supports compressed JSON format**
+
+Broker Load now supports importing compressed JSON format data, significantly reducing bandwidth requirements for data transmission and accelerating data import performance. [#30809](https://github.com/apache/doris/pull/30809)
+
+**7. TRUNCATE Function can use columns as scale parameters**
+
+The TRUNCATE function can now accept columns as scale parameters, providing more flexibility when processing numerical data. [#32746](https://github.com/apache/doris/pull/32746)
+
+**8. Add new functions `uuid_to_int` and `int_to_uuid`**
+
+These two functions allow users to convert between UUID and integer, significantly helping in scenarios that require handling UUID data. [#33005](https://github.com/apache/doris/pull/33005)
+
+**9. Add `bypass_workload_group` session variable to bypass query queue**
+
+The `bypass_workload_group` session variable allows certain queries to bypass the Workload Group queue and execute directly, which is useful for handling critical queries that require quick responses. [#33101](https://github.com/apache/doris/pull/33101)
+
+**10. Add strcmp function**
+
+The strcmp function compares two strings and returns their comparison result, simplifying text data processing. [#33272](https://github.com/apache/doris/pull/33272)
+
+**11. Support HLL functions `hll_from_base64` and `hll_to_base64`**
+
+HyperLogLog (HLL) is an algorithm for cardinality estimation. These two functions allow users to decode HLL data from a Base64-encoded string or encode HLL data as a Base64 string, which is very useful for storing and transmitting HLL data. [#32089](https://github.com/apache/doris/pull/32089)
+
+## Optimization and Improvements
+
+**1. Replace SipHash with XXHash to improve shuffle performance**
+
+Both SipHash and XXHash are hashing functions, but XXHash may provide faster hashing speeds and better performance in certain scenarios. This optimization aims to improve performance during data shuffling by adopting XXHash. [#32919](https://github.com/apache/doris/pull/32919)
+
+**2. Asynchronous materialized views support NULL partition columns in OLAP tables**
+
+This enhancement allows asynchronous materialized views to support NULL partition columns in OLAP tables, enhancing data processing flexibility.[#32698](https://github.com/apache/doris/pull/32698)
+
+**3. Limit maximum string length to 1024 when collecting column statistics to control BE memory usage**
+
+Limiting the string length when collecting column statistics prevents excessive data from consuming too much BE memory, helping maintain system stability and performance. [#32470](https://github.com/apache/doris/pull/32470)
+
+**4. Support dynamic deletion of Bitmap cache to improve performance**
+
+Dynamically deleting no longer needed Bitmap Cache can free up memory and improve system performance. [#32991](https://github.com/apache/doris/pull/32991)
+
+**5. Reduce memory usage during ALTER operations**
+
+Reducing memory usage during ALTER operations improves the efficiency of system resource utilization. [#33474](https://github.com/apache/doris/pull/33474)
+
+**6. Support constant folding for complex types**
+
+Supports constant folding for Array/Map/Struct complex types.[#32867](https://github.com/apache/doris/pull/32867)
+
+**7. Add support for Variant type in Aggregate Key Model**
+
+The Variant data type can store multiple data types. This optimization allows aggregation operations on Variant type data, enhancing the flexibility of semi-structured data analysis. [#33493](https://github.com/apache/doris/pull/33493)
+
+**8. Support new inverted index format in CCR** [#33415](https://github.com/apache/doris/pull/33415)
+
+**9. Optimize rewriting performance for nested materialized views** [#34127](https://github.com/apache/doris/pull/34127)
+
+**10. Support decimal256 type in row-based storage format**
+
+Supporting the decimal256 type in row-based storage extends the system's ability to handle high-precision numerical data. [#34887](https://github.com/apache/doris/pull/34887)
+
+## Behavioral Changes
+
+**1. Authorization**
+
+- **Grant_priv permission changes**: `Grant_priv` can no longer be arbitrarily granted. When performing a `GRANT` operation, the user not only needs to have `Grant_priv` but also the permissions to be granted. For example, to grant `SELECT` permission on `table1`, the user needs both `GRANT` permission and `SELECT` permission on `table1`, enhancing security and consistency in permission management. [#32825](https://github.com/apache/doris/pull/32825)
+
+- **Workload group and resource usage_priv**: `Usage_priv` for Workload Group and Resource is no longer global but limited to Resource and Workload Group, making permission granting and usage more specific. [#32907](https://github.com/apache/doris/pull/32907)
+
+- **Authorization for operations**: Operations that were previously unauthorized now have corresponding authorizations for more detailed and comprehensive operational permission control. [#33347](https://github.com/apache/doris/pull/33347)
+
+**2. LOG directory configuration**
+
+The log directory configuration for FE and BE now uniformly uses the `LOG_DIR` environment variable. All other different types of logs will be stored with `LOG_DIR` as the root directory. To maintain compatibility between versions, the previous configuration item `sys_log_dir` can still be used. [#32933](https://github.com/apache/doris/pull/32933)
+
+**3. S3 Table Function (TVF)**
+
+Due to issues with correctly recognizing or processing S3 URLs in certain cases, the parsing logic for object storage paths has been refactored. For file paths in S3 table functions, the `force_parsing_by_standard_uri` parameter needs to be passed to ensure correct parsing. [#33858](https://github.com/apache/doris/pull/33858)
+
+## Upgrade Issues
+
+Since many users use certain keywords as column names or attribute values, the following keywords have been set as non-reserved, allowing users to use them as identifiers. [#34613](https://github.com/apache/doris/pull/34613)
+
+## Bug Fixes
+
+**1. Fix no data error when reading Hive tables on Tencent Cloud COSN**
+
+Resolved the no data error that could occur when reading Hive tables on Tencent Cloud COSN, enhancing compatibility with Tencent Cloud storage services.
+
+**2. Fix incorrect results returned by `milliseconds_diff` function**
+
+Fixed an issue where the `milliseconds_diff` function returned incorrect results in some cases, ensuring the accuracy of time difference calculations. [#32897](https://github.com/apache/doris/pull/32897)
+
+**3. User-defined variables should be rorwarded to the Master node**
+
+Ensured that user-defined variables are correctly passed to the Master node for consistency and correct execution logic across the entire system. [#33013]https://github.com/apache/doris/pull/33013
+
+**4. Fix Schema Change issues when adding complex type columns**
+
+Resolved Schema Change issues that could arise when adding complex type columns, ensuring the correctness of Schema Changes. [#31824](https://github.com/apache/doris/pull/31824)
+
+**5. Fix data loss issue in Routine Load when FE Master node changes**
+
+`Routine Load` is often used to subscribe to Kafka message queues. This fix addresses potential data loss issues that may occur during FE Master node changes. [#33678](https://github.com/apache/doris/pull/33678)
+
+**6. Fix Routine Load failure when Workload Group cannot be found**
+
+Resolved an issue where `Routine Load` would fail if the specified Workload Group could not be found. [#33596](https://github.com/apache/doris/pull/33596)
+
+**7. Support column string64 to avoid join failures when string size overflows unit32**
+
+In some cases, string sizes may exceed the unit32 limit. Supporting the `string64` type ensures correct execution of string JOIN operations. [#33850](https://github.com/apache/doris/pull/33850)
+
+**8. Allow Hadoop users to create Paimon Catalog**
+
+Permitted authorized Hadoop users to create Paimon Catalogs.[#33833](https://github.com/apache/doris/pull/33833)
+
+**9. Fix `function_ipxx_cidr` function issues with constant parameters**
+
+Resolved problems with the `function_ipxx_cidr` function when handling constant parameters, ensuring the correctness of function execution.[#33968](https://github.com/apache/doris/pull/33968)
+
+**10. Fix file download errors when restoring using HDFS**
+
+Resolved "failed to download" errors encountered during data restoration using HDFS, ensuring the accuracy and reliability of data recovery. [#33303](https://github.com/apache/doris/issues/33303)
+
+**11. Fix column permission issues related to hidden columns**
+
+In some cases, permission settings for hidden columns may be incorrect. This fix ensures the correctness and security of column permission settings. [#34849](https://github.com/apache/doris/pull/34849)
+
+**12. Fix issue where Arrow Flight cannot obtain the correct IP in K8s deployments**
+
+This fix resolves an issue where Arrow Flight cannot correctly obtain the IP address in Kubernetes deployment environments.[#34850](https://github.com/apache/doris/pull/34850)

+  
+  Ignoring non-existent files helps to avoid query errors.
+
+- By default, creating a Bitmap Index will no longer be automatically changed to an Inverted Index. [#35521](https://github.com/apache/doris/pull/35521)
+
+  This behavior is controlled by the FE configuration item `enable_create_bitmap_index_as_inverted_index`, which defaults to false.
+
+- When starting FE and BE processes using `--console`, all logs will be output to the standard output and differentiated by prefixes indicating the log type. [#35679](https://github.com/apache/doris/pull/35679)
+
+	For more infomation, please see the documentations:
+	
+	- [Log Management - FE Log](../admin-manual/log-management/fe-log.md)
+
+	- [Log Management - BE Log](../admin-manual/log-management/be-log.md)
+
+- If no table comment is provided when creating a table, the default comment will be empty instead of using the table type as the default comment. [#36025](https://github.com/apache/doris/pull/36025)
+
+- The default precision of DECIMALV3 has been adjusted from (9, 0) to (38, 9) to maintain compatibility with the version in which this feature was initially released. [#36316](https://github.com/apache/doris/pull/36316)

+**Apache Doris version 2.1.5 was officially released on July 24, 2024.** In this update, we have optimized various functional experiences for data lakehouse and high concurrency scenarios, functionalities of asynchronous materialized views. Additionaly, we have implemented several improvemnents and bug fixes to enhance the stability. 
+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+## Behavior changes
+
+- The default connection pool size for the JDBC Catalog has been increased from 10 to 30 to prevent connection exhaustion in high-concurrency scenarios. [#37023](https://github.com/apache/doris/pull/37023). 
+
+- The system's reserved memory (low water mark) has been adjusted to `min(6.4GB, MemTotal * 5%)` to mitigate BE OOM issues.
+
+- When processing multiple statements in a single request, only the last statement's result is returned if the `CLIENT_MULTI_STATEMENTS` flag is not set.
+
+- Direct modifications to data in asynchronous materialized views are no longer permitted.[#37129](https://github.com/apache/doris/pull/37129)
+
+- A session variable `use_max_length_of_varchar_in_ctas` has been added to control the behavior of varchar and char type length generation during CTAS (Create Table As Select). The default value is true. When set to false, the derived varchar length is used instead of the maximum length. [#37284](https://github.com/apache/doris/pull/37284)
+
+- Statistics collection now defaults to enabling the functionality of estimating the number of rows in Hive tables based on file size. [#37694](https://github.com/apache/doris/pull/37694)
+
+- Transparent rewrite for asynchronous materialized views is now enabled by default. [#35897](https://github.com/apache/doris/pull/35897)
+
+- Transparent rewrite utilizes partitioned materialized views. If partitions fail, the base tables are unioned with the materialized view to ensure data correctness. [#35897](https://github.com/apache/doris/pull/35897)
+
+## New features
+
+### Lakehouse
+
+- The session variable `read_csv_empty_line_as_null` can be used to control whether empty lines are ignored when reading CSV format files. [#37153](https://github.com/apache/doris/pull/37153) 
+
+  By default, empty lines are ignored. When set to true, empty lines will be read as rows where all columns are null.
+
+- Compatibility with Presto's complex type output format can be enabled by setting `serde_dialect="presto"`. [#37253](https://github.com/apache/doris/pull/37253)
+
+### Multi-Table Materialized View
+
+- Supports non-deterministic functions in materialized view building. [#37651](https://github.com/apache/doris/pull/37651)
+
+- Atomically replaces definitions of asynchronous materialized views. [#37147](https://github.com/apache/doris/pull/37147)
+
+- Views creation statements can be viewed via `SHOW CREATE MATERIALIZED VIEW`. [#37125](https://github.com/apache/doris/pull/37125)
+
+- Transparent rewrites for multi-dimensional aggregation and non-aggregate queries. [#37436](https://github.com/apache/doris/pull/37436) [#37497](https://github.com/apache/doris/pull/37497)
+
+- Supports DISTINCT aggregations with key columns and partitioning for roll-ups. [#37651](https://github.com/apache/doris/pull/37651)  
+
+- Support for partitioning materialized views to roll up partitions using `date_trunc` [#31812](https://github.com/apache/doris/pull/31812) [#35562](https://github.com/apache/doris/pull/35562)
+
+- Partitioned table-valued functions (TVFs) are supported. [#36479](https://github.com/apache/doris/pull/36479)
+
+### Semi-Structured Data Management
+
+- Tables using the VARIANT type now support partial column updates. [#34925](https://github.com/apache/doris/pull/34925)
+
+- PreparedStatement support is now enabled by default. [#36581](https://github.com/apache/doris/pull/36581)
+
+- The VARIANT type can be exported to CSV format. [#37857](https://github.com/apache/doris/pull/37857)
+
+- `explode_json_object` function transposes JSON Object rows into columns. [#36887](https://github.com/apache/doris/pull/36887)
+
+- The ES Catalog now maps ES NESTED or OBJECT types to the Doris JSON type.[#37101](https://github.com/apache/doris/pull/37101)
+
+- By default, support_phrase is enabled for inverted indexes with specified analyzers to improve the performance of match_phrase series queries. [#37949](https://github.com/apache/doris/pull/37949)
+
+### Query Optimizer
+
+- Support for explaining `DELETE FROM` statements. [#37100](https://github.com/apache/doris/pull/37100)
+
+- Support for hint form of constant expression parameters [#37988](https://github.com/apache/doris/pull/37988)
+
+### Memory Management
+
+- Added an HTTP API to clear the cache. [#36599](https://github.com/apache/doris/pull/36599)
+
+### Permissions
+
+- Support for authorization of resources within Table-Valued Functions (TVFs) [#37132](https://github.com/apache/doris/pull/37132)
+
+## Improvements
+
+### Lakehouse
+
+- Upgraded Paimon to version 0.8.1
+
+- Fixes ClassNotFoundException for org.apache.commons.lang.StringUtils when querying Paimon tables. [#37512](https://github.com/apache/doris/pull/37512)
+

+
+- Configurable via the session variable `fetch_splits_max_wait_time_ms`.
+
+- Improved default connection logic for SQLServer JDBC Catalog. [#36971](https://github.com/apache/doris/pull/36971)
+
+  By default, the connection encryption settings are not intervened. Only when `force_sqlserver_jdbc_encrypt_false` is set to true, encrypt=false is forcibly added to the JDBC URL to reduce authentication errors. This allows for more flexible control over encryption behavior, enabling it to be turned on or off as needed.
+
+- Added serde properties to the show create table statements for Hive tables. [#37096](https://github.com/apache/doris/pull/37096)
+
+- Changed the default cache time for Hive table lists on the FE from 1 day to 4 hours
+
+- Data export (Export/Outfile) now supports specifying compression formats for Parquet and ORC
+
+  For more information, please refer to [docs](https://doris.apache.org/docs/sql-manual/sql-statements/Data-Manipulation-Statements/Manipulation/EXPORT/?_highlight=compress_type).
+
+- When creating a table using CTAS+TVF, partition columns in the TVF are automatically mapped to Varchar(65533) instead of String, allowing them to be used as partition columns for internal tables [#37161](https://github.com/apache/doris/pull/37161)
+
+- Optimized the number of metadata accesses for Hive write operations [#37127](https://github.com/apache/doris/pull/37127)
+
+- ES Catalog now supports mapping nested/object types to Doris's Json type. [#37182](https://github.com/apache/doris/pull/37182)
+
+- Improved error messages when connecting to Oracle using older versions of the ojdbc driver [#37634](https://github.com/apache/doris/pull/37634)
+
+- When Hudi tables return an empty set during Incremental Read, Doris now also returns an empty set instead of error [#37636](https://github.com/apache/doris/pull/37636)
+

+## Upgrade suggestions
+
+When upgrading Doris, please follow the principle of not skipping two minor versions and upgrade sequentially.
+
+For example, if you are upgrading from version 0.15.x to 2.0.x, it is recommended to first upgrade to the latest version of 1.1, then upgrade to the latest version of 1.2, and finally upgrade to the latest version of 2.0.
+
+For more upgrade information, see the documentation: [Cluster Upgrade](../../admin-manual/cluster-management/upgrade)

+
+We are excited to announce the release of Apache Doris 3.0! 
+
+**Starting from version 3.X, Apache Doris supports a compute-storage decoupled mode in addition to the compute-storage coupled mode for cluster deployment. With the cloud-native architecture that decouples the computation and storage layers, users can achieve physical isolation between query loads across multiple compute clusters, as well as isolation between read and write loads. Additionally, users can take advantage of low-cost shared storage systems such as object storage or HDFS to significantly reduce storage costs.**
+
+Version 3.0 marks a milestone in the evolution of Apache Doris towards a unified data lake and data warehouse architecture. This version introduces the ability to write data back to data lakes, allowing users to perform data analysis, sharing, processing, and storage operations across multiple data sources within Apache Doris. With capabilities such as asynchronous materialized views, Apache Doris can serve as a unified data processing engine for enterprises, helping users better manage data across lakes, warehouses, and databases. Also, Apache Doris 3.0 introduces the Trino Connector. It allows users to quickly connect or adapt to more data sources, and leverage the high-performance compute engine of Doris to deliver faster query results than Trino.
+
+Version 3.0 also enhances support for ETL batch processing scenarios, adding explicit transaction support for operations like `insert into select`, `delete` and `update`. The observability of query execution has also been improved.
+
+In terms of performance, we have improved the framework capabilities, infrastructure, and rules of the query optimizer in version 3.0. This provides optimized performance, which has been proven by blind testing in more complex and diverse business scenarios.
+
+The adaptive Runtime Filter computation method now accurately estimates filters based on data size during execution, delivering better performance under large data volumes and high loads. Additionally, asynchronous materialized view has been more stable and user-friendly in query acceleration and data modeling. 
+
+**During the development of version 3.0, over 200 contributors submitted nearly 5,000 optimizations** and fixes to Apache Doris. Contributors from companies such as VeloDB, Baidu, Meituan, ByteDance, Tencent, Alibaba, Kwai, Huawei, and Tianyi Cloud actively collaborated with the community, contributing test cases from real-world use cases to help us improve Apache Doris. We extend our heartfelt thanks to all the contributors involved in the development, testing, and feedback process for this release.

+## 1. Compute-storage decoupled mode
+
+Since V3.0, Apache Doris supports the compute-storage decoupled mode. Users can choose between it and the compute-storage coupled mode during cluster deployment.
+
+In the compute-storage decoupled mode, the BE nodes no longer store the data, but instead, a shared storage layer (HDFS and object storage) is introduced as the shared data storage layer. The computing and storage resources can be scaled independently, bringing multiple benefits to users:
+
+- **Workload isolation**: Multiple compute clusters can share the same data, allowing users to isolate different business workloads or offline loads using separate compute clusters.
+
+- **Reduced storage costs**: The full dataset is stored in the more cost-effective and highly reliable shared storage, with only hot data cached locally. Compared to the compute-storage coupled mode with three data replicas, the storage cost can be reduced by up to 90%.
+
+- **Elastic computing resources**: Since no data is stored on the BE nodes, the computing resources can be scaled flexibly based on the load requirements. Users can scale in or out an individual compute cluster or increase/decrease the number of compute clusters. This also leads to cost savings.
+
+- **Improved system robustness**: By storing the data in shared storage, Doris no longer needs to handle the complex logic of multi-replica consistency, thus simplifying distributed storage complexity and improving the overall system robustness.
+
+- **Flexible data sharing and cloning**: The flexibility of the compute-storage decoupled mode extends beyond a single Doris cluster. Tables from one Doris cluster can be easily cloned to another Doris cluster, with just metadata replication.
+
+### 1-1. From coupled to decoupled
+
+In the compute-storage coupled mode, the Apache Doris architecture consists of two main process types: Frontend (FE) and Backend (BE). The FE is primarily responsible for user request access, query parsing and planning, metadata management, and node management. The BE is responsible for data storage and query plan execution. 
+
+The BE nodes employ an MPP (Massively Parallel Processing) distributed computing architecture, leveraging a multi-replica consistency protocol to ensure high service availability and high data reliability.
+
+![From coupled to decoupled](/images/storage-compute-decoupled.PNG)
+
+
+The maturation of emerging cloud computing infrastructure, including public clouds, private clouds, and Kubernetes-based container platforms, has driven the need for cloud-native capabilities. Increasingly, users are seeking deeper integration between Apache Doris and cloud computing infrastructure to provide more elasticity.
+
+**To address this need, the VeloDB team has designed and implemented a cloud-native version of Apache Doris that decouples compute and storage, known as VeloDB Cloud.  After extensive production testing and refinement across hundreds of enterprises over a long time, this cloud-native solution has now been contributed to the Apache Doris community, manifesting as the Apache Doris 3.0 in the compute-storage decoupled mode.**
+
+In the compute-storage decoupled mode, the Apache Doris architecture consists of three layers:
+
+- **Meta data layer**: A new Meta Service module has been introduced to provide meta data services, such as processing database and table information, schemas, rowset meta, and transactions. The Meta Service is stateless and horizontally scalable. In V3.0, all of the BE's meta data and parts of the FE's meta data have been migrated to the Meta Service. We will finish the migration of the remains in future versions.
+- **Computation layer**: The stateless BE nodes execute query plans and cache a portion of the data and tablet meta data locally to improve query performance. Multiple stateless BE nodes can be organized into a computing resource pool (i.e., compute cluster), and multiple compute clusters can share the same data and metadata service. The compute clusters can be elastically scaled by adding or removing nodes as needed.
+- **Shared storage layer**: Data is persisted to the shared storage layer, which currently supports HDFS as well as various cloud-based object storage systems that are compatible with the S3 protocol, such as S3, OSS, GCS, Azure Blob, COS, BOS, and MinIO.
+
+![From coupled to decoupled-2](/images/storage-compute-decoupled-2.JPEG)
+
+### 1-2 Design highlight
+
+The design of the compute-storage decoupled mode of Apache Doris highlights the transformation of the FE's in-memory metadata model into a shared metadata service. This approach offers a globally consistent state view, allowing any node to directly submit writes without needing to go through the FE for publishing. During write operations, data is stored in shared storage, while metadata is managed by the metadata service. **This effectively controls the number of small files in shared storage. Meanwhile, the real-time write performance for individual tables is nearly on par with that in the compute-storage coupled mode. The system's overall write capacity is no longer limited by the processing power of a single FE node.**
+
+![Design highlight](/images/design-hightlight.PNG)
+
+Based on the globally consistent state view, for data garbage collection, we have adopted a design approach for data deletion that is easier to prove correct and more efficient.
+
+Specifically, data in the shared storage is incorporated into the globally consistent view offered by the shared meta data service. Whenever data is generated, we bind it to a separate, independent transaction. Similarly, for a meta data deletion operation, we also bind it to a separate, independent transaction. The purpose of this approach is to ensure that deletion and write operations cannot succeed together. The view records which data needs to be deleted, and the asynchronous deletion process can simply perform a forward deletion of the data based on the transaction records, without the need for reverse garbage collection.
+
+As the tablet-related meta data in the FE is gradually migrated to the shared meta data service, the scalability of the Doris cluster will no longer be constrained by the memory capacity of a single FE node. Building upon the shared meta data service and the forward data deletion technique, we can conveniently expand functionality such as data sharing and lightweight cloning.
+
+### 1-3 Comparison with alternative solutions
+
+Another design of decoupling compute and storage in the industry is to store the data and BE node meta data in a shared object storage or HDFS. However, this approach brings the following problems:
+
+- **Inability to support real-time writes**: During data writes, the data is mapped to tablets based on the partitioning and bucketing rules, generating segment files and rowset meta data. During the write process, a two-phase commit (Publish) is performed through the FE. When a BE node receives the Publish request, it then sets the rowset as visible. The Publish operation must not fail. If the rowset meta data is stored in the shared storage, the total small file data during the real-time write process would triple the size of the actual data files - one replica of data files, one for rowset meta data, and another for rowset meta data changes during Publish. The Publish operation is driven by a single FE node, so the write capacity of a single table or even the entire system is limited by the FE node's capabilities.
+  
+  ![Comparison with alternative solutions](/images/comparison-with-alternative-solutions.png)
+
+  We compared the real-time data write performance of Apache Doris 3.0 with the above-described solution. We simulated 500 concurrent tasks writing 10,000 data files with 500 rows each, and 50 concurrent tasks writing 250 data files with 20,000 rows each, using the same computational resources. 
+
+  **The results showed that at 50 concurrent tasks, the micro-batch write performances of Apache Doris in both compute-storage coupled and decoupled modes were almost identical, while the industry solution lagged behind Apache Doris by a factor of 100.** 
+
+  At 500 concurrent tasks, the performance of Apache Doris in the compute-storage decoupled mode showed slight degradation, but it still maintained an 11X advantage over the industry solution. To ensure a fair test, Apache Doris did not enable the Group Commit feature (which the industry solution lacks). Enabling Group Commit would further enhance real-time write performance.
+
+  ![Comparison with alternative solutions](/images/real-time-write-performance..png)
+
+  Additionally, the industry solution also faces stability and cost issues in terms of real-time data ingestion:
+
+  - Stability concerns: A large number of small files can put pressure on the shared storage, especially HDFS, and introduce stability risks.
+
+  - High object storage request costs: Some public cloud object storage services charge 10 times more for Put and Delete operations compared to Get operations. A large number of small files can lead to a significant increase in object storage request costs, which can even exceed the storage costs.
+
+- **Limited scalability**: Use cases of the compute-storage decoupled model often handles larger data storage sizes, since the FE (Frontend) meta data is entirely in-memory, when the number of tablets reaches a certain high level (e.g. tens of millions), the FE's memory pressure can become a bottleneck that limits the overall write throughput of the system.
+
+- **Potential data deletion logic issues**: In the compute-storage decoupled architecture, data is stored with one single replica. Therefore, the data deletion logic is critical for the system's reliability. The conventional approach of cross-system data deletion by comparing the differences can be challenging. During the write process, there is no way to completely avoid deletion and write from succeeding together, which can lead to data loss. Additionally, when the storage system experiences anomalies, the input used for difference calculation may be incorrect, which potentially leads to unintended data deletion.
+
+- **Data sharing and lightweight cloning**: The flexibility of the decoupled storage-compute architecture can enable future data sharing and lightweight data cloning, reducing the burden of enterprise data management. However, if each cluster has a separate FE, after cloning data across clusters, it becomes difficult to accurately determine which data is no longer referenced and can be safely deleted, as calculating cross-cluster references can easily lead to unintended data deletion.
+
+By evolving the FE's full in-memory meta data model into a shared meta data service, Apache Doris 3.0 avoids all the aforementioned issues.
+
+### 1-4 Query performance comparison
+
+In the compute-storage decoupled mode, data needs to be read from the remote shared storage system, the main bottleneck has become the network bandwidth instead of the disk I/O in the compute-storage coupled mode. 
+
+To accelerate data access, Apache Doris has implemented a high-speed caching mechanism based on local disks, and provides two cache management policies: LRU (Least Recently Used) and TTL (Time-To-Live). The newly imported data is asynchronously written to the cache to accelerate the first-time access to the latest data. If the data required by a query is not in the cache, the system will read the data from the remote storage into memory and synchronously write it to the cache for subsequent queries.
+
+In use cases involving multiple compute clusters, Apache Doris provides a cache preheating function. When a new compute cluster is established, users can choose to preheat specific data (such as tables or partitions) to further improve query efficiency.
+
+In this context, we have conducted performance tests with different caching strategies in both the compute-storage coupled and decoupled modes, using the TPC-DS 1TB test dataset. The results are concluded as follows:
+
+- When the cache is fully hit (i.e., all the data required for the query is loaded into the cache), **the query performance of the compute-storage decoupled mode is on par with that of the compute-storage coupled mode**.
+
+- When the cache is partially hit (i.e., the cache is cleared before the test, and data is gradually loaded into the cache during the test, with performance continuously improving), the query performance of the compute-storage decoupled mode is about 10% lower than that of the compute-storage coupled mode. This test scenario is the most similar to the real-life use cases.
+
+- When the cache is completely missed (i.e., the cache is cleared before every SQL execution, simulating an extreme case), the performance loss is around 35%. **Even so, Apache Doris in the compute-storage decoupled mode delivers much higher performance than its alternative solutions.**
+
+![Query performance comparison](/images/query-performance-comparison.png)
+
+### 1-5 Write speed comparison
+
+In terms of write performance, we have simulated two test cases under the same computing resources: batch import and high-concurrency real-time import. The comparison of write performance between the compute-storage coupled mode and the compute-storage decoupled mode is as follows:
+
+- **Batch import**: When importing the 1TB TPC-H and 1TB TPC-DS test datasets, **the write performance of the compute-storage decoupled mode is 20.05% and 27.98% higher than the compute-storage coupled mode**, respectively, under the single-replica configuration. During batch import, the segment file size is generally in the range of tens to hundreds of MB. In the compute-storage decoupled mode, the segment files are split into smaller files and concurrently uploaded to the object storage, which can result in higher throughput compared to writing to local disks. In real-life deployments, the compute-storage coupled mode typically uses three replicas, which means the write speed advantage of the compute-storage decoupled mode will be even more pronounced.
+
+- **High-concurrency real-time import**: as described in the "Comparison with alternative solutions" section.
+
+![Write speed comparison](/images/write-speed-comparison.png)
+
+### 1-6 Tips for production environment
+
+- **Performance**: For real-time data analysis, users can achieve query performance comparable to the compute-storage coupled mode by specifying a TTL (Time-To-Live) for the cache and writing newly ingested data into the cache. To prevent query jitter, users can cache the data generated by background tasks such as compaction and schema changes based on how frequently used the data is.
+
+- **Workload isolation**: Users can achieve physical resource isolation for different business using multiple compute clusters. For workload isolation within a single compute cluster, users can utilize the Workload Group mechanism to limit and isolate resources for different queries.
+
+### 1-7 Notes
+
+- Apache Doris 3.0 does not support the co-existence of the compute-storage coupled mode and the compute-storage decoupled mode. Users need to specify one of them during cluster deployment.
+
+- If users need the compute-storage coupled mode, following the [documentation](https://doris.apache.org/docs/3.0/install/source-install/compilation-with-docker/) for its deployment and upgrade. We recommend using Doris Manager for quick deployment and cluster upgrades. However, the compute-storage decoupled mode does not yet support Doris Manager deployment and upgrade. We will continue iteration for better support in future versions.
+
+- Currently Apache Doris does not support in-place upgrade from V2.1 to the compute-storage decoupled mode of V3.0. For such purpose, users need to perform data migration using tools like X2Doris after deploying the compute-storage decoupled clusters. In the future, we will support migration without service interruption through the CCR (Change Data Capture) capability.

+
+## 2. Data lakehouse
+
+Apache Doris is positioned as a real-time data warehouse, but it is much more than that. In previous versions, we have consistently pushed beyond the boundaries of traditional data warehouse capabilities, advancing towards a unified data lakehouse. Version 3.0 marks a milestone in this journey, with its capabilities in the lakehouse architecture becoming fully mature. We believe that a unified lakehouse is identified by **boundaryless data** and **lakehouse fusion**:
+
+**Boundaryless data: Apache Doris serves as a unified query processing engine, breaking down data barriers across different systems. It provides a consistent and ultra-fast analysis experience across all data sources, including data warehouses, data lakes, data streams, and local data files.**
+
+- **Lakehouse query acceleration**: Without the need to migrate data to Apache Doris, users can leverage Doris’ efficient query engine to directly query data stored in data lakes such as Iceberg, Hudi, Paimon, and offline data warehouses like Hive, thereby accelerating query analysis.
+
+- **Federated analysis**: By extending its catalog and storage plugins, Apache Doris enhances its federated analysis capabilities, allowing users to perform unified analysis across multiple heterogeneous data sources without physically centralizing the data in a single storage system. This enables external table queries and federated joins between internal and external tables, breaking down data silos and providing globally consistent data insights.
+
+- **Data lake construction**: Apache Doris introduces write-back functionality for Hive and Iceberg, allowing users to directly create Hive and Iceberg tables through Doris and write data into them. This allows users to write internal table data back to the offline lakehouse or process offline lakehouse data using Doris and save the results back into the lakehouse, simplifying and streamlining the data lake construction process.
+
+**Lakehouse fusion: As data lake architectures become increasingly complex, the costs of technology selection and maintenance rise for users. Achieving consistent fine-grained access control across multiple systems also becomes challenging, and real-time performance suffers. To address this, Apache Doris integrates core features of the data lake, transforming itself into a lightweight, efficient, native real-time lakehouse.**
+
+- **Real-time data updates**: Starting with version 1.2, Apache Doris enhanced the primary key model by introducing Merge-on-Write, supporting real-time updates. This feature allows high-frequency, real-time data updates based on primary key changes from upstream data sources.
+
+- **Data science and** **AI** **computation support**: From version 2.1, Apache Doris, using the efficient Arrow Flight protocol, increased the openness of its storage system and its support for various compute loads, enabling data science and AI computations.
+
+- **Enhancements for semi-structured and unstructured Data**: Apache Doris has introduced support for data types like Array, Map, Struct, JSON, and Variant, with plans to support vector indexing in the future.
+
+- **Improved resource efficiency by decoupling storage and compute**: With version 3.0, Apache Doris supports a decoupled storage and compute mode, further improving resource efficiency and scalability.
+
+### 2-1 Faster queries in the data lakehouse
+
+TPC-H and TPC-DS benchmarking proves that Apache Doris achieves average query performance that is 3 to 5 times faster than Trino/Presto.
+
+In V3.0, we have focused on optimizing query performance for production environments, including:
+
+- **More granular task splitting strategy**: By adjusting the consistent hashing algorithm and introducing a task sharding weighting mechanism, we ensure balanced query loads across all nodes.
+
+- **Scheduling optimizations for use cases with numerous partitions and files**: For cases with a large number of files (over 1 million), we have largely reduced query latency (from 100 seconds to 10 seconds) and alleviated memory pressure on the Frontend (FE) by asynchronously and batch-fetching file shards.
+
+We will continue to specifically enhance query acceleration performance in real-world business scenarios, improve the actual user experience, and build an industry-leading lakehouse query acceleration engine.
+
+### 2-2 Federated analysis: more data connectors
+
+Previous versions of Apache Doris support connectors for over 10 mainstream data lakehouses, warehouses, and relational databases. In V3.0, we have introduced the Trino Connector compatibility framework, which expands the range of data sources that Apache Doris can connect to. With this framework, users can easily adapt their existing setups to access corresponding data sources using Doris and leverage its high-speed computing engine for data analysis.
+
+Currently, Doris has completed adaptations for Delta Lake, Kudu, BigQuery, Kafka, TPCH, and TPCDS. We also encourage contributions from developers to prolong this list.

+
+
+### 2-3 Data lake building
+
+In V3.0, we have introduced data writeback functionality for Hive and Iceberg. This allows users to create Hive and Iceberg tables directly through Doris and write data into these tables, and enables users to perform data analysis, sharing, processing, and storage operations across multiple data sources within Doris.
+
+In future iterations, Apache Doris will further enhance support for data lake table formats and improve the openness of storage APIs.
+
+:::info Note
+See doc: https://doris.apache.org/docs/3.0/lakehouse/datalake-building/hive-build/
+:::
+
+## 3. Upgraded semi-structured data analysis capabilities
+
+In versions 2.0 and 2.1, Apache Doris introduced some well-embraced features such as inverted index, NGram Bloom Filter, and Variant data type to support high-performance full-text search and multi-dimensional analysis. With them, the storage and processing of complex semi-structured data have been more flexible and efficient.
+
+In V3.0, we have further enhanced the capabilities in this scenario.
+
+After extensive testing in production environments, the Variant data type has gained sufficient stability and become the preferred choice for JSON data storage and analysis. In V3.0, we have made multiple optimizations to it:
+
+- Support for indexing of the Variant data type to accelerate queries, including inverted index, Bloom Filter index, and the built-in ZoneMap index.
+
+- Support for flexible partial column updates for Unique Key tables containing the Variant data type.
+
+- Support for the use of the Variant data type in the compute-storage decoupled mode, with optimizations of its metadata storage.
+
+- Support for exporting the Variant data type to formats such as Parquet and CSV.
+
+The inverted index, introduced since V2.0, has reached a high level of maturity after more than a year of refinement and is now running in production environments of hundreds of enterprises. In V3.0, we have made multiple optimizations to the inverted index:
+
+- After performance optimizations, including lock concurrency, Apache Doris outperforms Elasticsearch in key metrics such as query latency and concurrency in real-time reporting analysis.
+
+- Optimized index file in the compute-storage decoupled mode to reduce remote storage calls and decrease index query latency.
+
+- Support for the Array data type to accelerate the `array_contains` queries.
+
+- Enhanced the `match_phrase_*` functionality, including support for slop and phrase prefix matching `match_phrase_prefix`.
+
+## 4. Enhanced ETL capabilities
+
+### 4-1. Transaction improvements
+
+Data processing in data warehouses often involves multiple data changes that need to be handled as a single transaction. V3.0 provides explicit transaction support for `insert into select`, `delete`, and `update` operations. Example cases include:
+
+- **Transactional requirements**: For example, when updating data within a time range, the typical approach is to first delete the data in that time range, and then insert the new data. Considering that the data might already be in service, there is a need to ensure that queries visit either the old data or the new data. Thus, it can be achieved by executing the `delete` and `insert into select` operations in a transaction.
+
+  ```Java
+  BEGIN;
+  DELETE FROM table WHERE date >= "2024-07-01" AND date <= "2024-07-31";
+  INSERT INTO table SELECT * FROM stage_table;
+  COMMIT;
+  ```
+
+- **Simplified the processing of failed tasks**: For example, when two `insert into select` operations are executed within a single transaction, if any of the operations fail, it can be retried directly.
+  
+  ```Java
+  BEGIN WITH LABEL label_etl_1;
+  INTO table1 SELECT * FROM stage_table1;
+  INSERT INTO table SELECT * FROM stage_table;
+  COMMIT;
+  ```
+
+:::info Note
+See doc: https://doris.apache.org/docs/3.0/data-operate/transaction/
+Currently, explicit transaction synchronization is not supported in Cross-Cluster Replication (CCR).
+:::
+
+### 4-2. Improved observability
+
+- **Real-time profile retrieval**: In previous versions, due to issues with the execution plan or the data, some complex queries might have high computational requirements, so developers can only access the query profile for performance analysis after the completion of the query. This makes it hard to promptly identify issues in query execution to guarantee stability of the production environment. Now, with the ability to retrieve real-time profiles, V3.0 allows users to monitor query execution as the query is running. It also allows them to better monitor the progress of each ETL job.
+
+- **`backend_active_tasks` system table**: The `backend_active_tasks` system table provides real-time resource consumption information for each query on each BE node. Users can analyze this system table using SQL to obtain the resource usage of each query, which helps identify large queries or abnormal workloads.
+
+## 5. Asynchronous materialized view
+
+In V3.0, asynchronous materialized view is faster and more stable. It is also more user-friendly for query acceleration and data modeling scenarios. We have restructured the logic for transparent rewrite and expanded its capabilities, making it 2X faster.
+
+### 5-1 Refresh
+
+- Support for incremental update of materialized views by partitions and partition roll-ups on materialized views to allow refreshes at different granularities.
+
+- Support for nested materialized views, which is useful in data modeling scenarios.
+
+- Support for index creation and sort key specification in asynchronous materialized views, which will improve query performance after the materialized view is hit.
+
+- Higher usability of materialized view DDL with support for atomically replacing materialized views, allowing modifications to the materialized view definition SQL while keeping the materialized view available. 
+
+- Support for non-deterministic functions in materialized views to better serve daily materialized view creation.
+
+- Support for trigger-based materialized view refresh, which ensures data consistency in data modeling with nested materialized views.
+
+- Support for a broader range of SQL patterns for building partitioned materialized views, making the incremental update capability available to more use cases.
+
+### 5-2 Refresh stability
+
+- V3.0 supports specifying a Workload Group for building materialized views. This is to limit the resources used by the materialized view build process and ensure that sufficient resources remain available for ongoing queries.
+
+### 5-3 Transparent rewrite
+
+- Support for transparent rewrite of more Join types, including derived Joins. Even when there is a mismatch of Join types between the query and materialized view, transparent rewrite can still be performed by compensating with additional predicates, as long as the materialized view can provide all the data needed for the query.
+
+- Support for more aggregate functions for roll-up as well as rewrite of multi-dimensional aggregations like GROUPING SETS, ROLLUP, and CUBE; support rewriting queries with aggregations when the materialized view does not contain aggregations, simplifying Join operations and expression computation.
+
+- Support for transparent rewrite of nested materialized views, enabling higher performance for complex queries.
+
+- For partially invalid partitioned materialized views, V3.0 supports `Union All` the base tables for data completion, expanding the applicability of partitioned materialized views.
+
+### 5-4 Transparent rewrite performance
+
+- Continuous optimization has been done to improve the transparent rewrite performance, achieving 2X the speed compared to version 2.1.0.

+
+:::
+
+## 6. Performance improvement
+
+### 6-1 Smarter optimizer
+
+In V3.0, the query optimizer has been enhanced in terms of framework capabilities, distributed plan support, optimizer infrastructure, and rule expansion. It provides better optimization capabilities for more complex and diverse business scenarios, with higher blind test performance for complex SQL:
+
+- **Improved plan enumeration capability**: The key structure Memo for plan enumeration has been restructured and normalized. This improves the efficiency of the Cascades framework in plan enumeration and the possibility of producing better plans. Additionally, it fixes incomplete column pruning during the Join Reorder process in older versions, which led to unnecessary overhead of the Join operator, thus improving the execution performance in the relevant scenarios.
+
+- **Improved distributed plan support**: The distributed query plan has been enhanced to allow aggregation, join, and window function operations to more intelligently identify the data characteristics of intermediate computation results, avoiding ineffective data redistribution operations. Meanwhile, we have optimized the execution under the multi-replica continuous execution mode, making it more data cache-friendly.
+
+- **Improved optimizer infrastructure**: V3 has fixed several issues in cost model and statistics information estimation. The fixes to the cost model are more adaptable to the evolution of the execution engine, making the execution plan more stable compared to previous versions.
+
+- **Enhanced Runtime Filter plan support**: On the basis of Join Runtime Filter, V3.0 has expanded the capability of the TopN Runtime Filter to achieve better performance in use cases that involve a TopN operator.
+
+- **Enriched optimization rule library**: Based on user feedback and internal testing results, we have introduced optimization rules such as Intersect Reorder to enrich the rule set of the optimizer.
+
+### 6-2 Self-adaptive Runtime Filter
+
+In previous versions, the generation of Runtime Filter relies on manual setting by users based on statistical information. However, inaccurate settings in certain cases could lead to performance instability.
+
+In V3.0, Doris implements a self-adaptive Runtime Filter calculation approach. It can estimate the Runtime Filter at runtime based on the data size with high accuracy, enabling better performance in use cases with large data volumes and high workloads. 
+
+### 6-3 Function performance optimization
+
+- V3.0 has improved the vectorized implementation of dozens of functions, enabling a performance improvement of over 50% for some commonly used functions.
+- V3.0 has also made extensive optimizations to the aggregation of nullable data types, enabling a 30% performance improvement.
+
+### 6-4 Blind test performance improvement
+
+Our blind tests on V3.0 and V2.1 show that the new version is 7.3% and 6.2% faster in TPC-DS and TPC-H benchmark tests, respectively.
+
+![Blind test performance improvement](/images/blind-test-performance-improvement.png)
+
+## 7. New features
+
+### 7-1 Java UDTF
+
+Version 3.0 has added support for Java UDTFs. The key operations are as follows:
+
+- Implementing a UDTF: Similar to a UDF, a UDTF requires the user to implement an `evaluate` method. Note that the return value of a UDTF function must be of the `Array` data type.
+
+  ```sql
+  public class UDTFStringTest {
+      public ArrayList<String> evaluate(String value, String separator) {
+          if (value == null || separator == null) {
+              return null;
+          } else {
+              return new ArrayList<>(Arrays.asList(value.split(separator)));
+          }
+      }
+  }
+  ```
+
+- Creating a UDTF: By default, two corresponding functions will be created - `java-utdf`and `java-utdf_outer`. The `_outer` suffix adds a single row of `NULL` data when the table function generates 0 rows of output.
+
+  ```sql
+  CREATE TABLES FUNCTION java-utdf(string, string) RETURNS array<string> PROPERTIES (
+      "file"="file:///pathTo/java-udaf.jar",
+      "symbol"="org.apache.doris.udf.demo.UDTFStringTest",
+      "always_nullable"="true",
+      "type"="JAVA_UDF"
+  );
+  ```
+
+:::info
+
+See doc: https://doris.apache.org/docs/3.0/query/udf/java-user-defined-function/#udtf-1
+
+:::
+
+### 7-2 Generated column
+
+A generated column is a special column whose value is calculated from the values of other columns rather than directly inserted or updated by the user. It supports pre-computing the results of expressions and storing them in the database, which is suitable for scenarios that require frequent queries or complex calculations.
+
+Results can be automatically calculated based on predefined expressions when data is imported or updated, and then stored persistently. In this way, during subsequent queries, the system can directly access these calculated results without performing complex calculations, thereby improving query performance.
+
+Generated columns are supported since V3.0. When creating a table, you can specify a column as generated column. A generated column automatically calculates values based on the defined expression when data is written. Generated columns allow for more complex expressions to be defined, but the value cannot be explicitly written or set.
+
+:::info
+
+See doc: https://doris.apache.org/docs/3.0/sql-manual/sql-statements/Data-Definition-Statements/Create/CREATE-TABLE-AND-GENERATED-COLUMN/
+
+:::
+
+## 8. Functional improvements
+
+### 8-1. Materialized view
+
+We have refactored the selection logic for materialized views and migrated it from the rule-based optimizer (RBO) to the cost-based optimizer (CBO). This aligns the selection logic with that of asynchronous materialized views. This functionality is enabled by default. If any issues are encountered, you can revert to the RBO mode using `set global enable_sync_mv_cost_based_rewrite = false`.
+
+### 8-2. Routine Load
+
+In previous versions, the Routine Load functionality faced some usability challenges, such as uneven task scheduling across BE nodes, untimely task scheduling, complex configuration requirements (the need to change multiple FE and BE settings for optimization), insufficient overall stability (where restarts or upgrades could frequently pause Routine Load jobs, requiring manual user intervention to resume).
+
+To address these issues, we have made extensive optimizations to the Routine Load feature:
+
+- **Resource scheduling**: We have improved the scheduling balance to make sure that tasks are more evenly distributed across BE nodes. Jobs that encounter unrepairable errors will be promptly paused to avoid wasting resources on futile scheduling attempts. Additionally, we have improved the timeliness of the scheduling process, which has enhanced the import performance of Routine Load.
+
+- **Parameter configuration**: Users in most environments no longer need to modify FE and BE configurations for optimization. An automatic adjustment mechanism with timeout parameter has been introduced to prevent tasks from constantly retrying when cluster pressure increases.
+
+- **Stability**: We have enhanced the robustness of Doris in various exceptional scenarios, such as FE failovers, BE rolling upgrades, and Kafka cluster anomalies, ensuring continuous stable operation. We have also optimized the Auto Resume mechanism, allowing Routine Load to automatically resume operation after faults are repaired, reducing the need for manual user intervention.
+
+## 9. Behavior changed
+
+- `cpu_resource_limit` will no longer be supported, and all types of resource isolation will be implemented through Workload Groups.
+
+- Please use JDK 17 for Apache Doris 3.0 and later versions. The recommended version being `jdk-17.0.10_linux-x64_bin.tar.gz`.
+
+## Try Apache Doris 3.0 now!
+
+Before the official release of version 3.0, the compute-storage decoupled mode of Apache Doris has undergone nearly two years of extensive testing and optimization in the production environments of hundreds of enterprises. Contributors from many tech giants have collaborated with the community to provide a significant number of test cases based on their real-world business needs. This has rigorously validated the usability and stability of version 3.0.
+
+We highly recommend users with compute-storage decoupling needs to download version 3.0 and experience it firsthand.
+
+Going forward, we will accelerate our release iteration cycle to deliver a more stable version experience for all users. Feel free to join us in the [Apache Doris community](https://join.slack.com/t/apachedoriscommunity/shared_invite/zt-2gmq5o30h-455W226d79zP3L96ZhXIoQ) and engage directly with the core developers.

+Dear community members, the Apache Doris 3.0.1 version was officially released on August 23, 2024, featuring updates and improvements in compute-storage decoupling, lakehouse, semi-structured data analysis, asynchronous materialized views, and more.
+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+## Behavior Changes
+
+### Query Optimizer
+
+- Added the variable `use_max_length_of_varchar_in_ctas` to control the length behavior of VARCHAR type when executing `CREATE TABLE AS SELECT` (CTAS) operations.  [#37069](https://github.com/apache/doris/pull/37069)
+  
+  - This variable is set to true by default. 
+  
+  - When set to true, if the VARCHAR type column originates from a table, the derived length is used; otherwise, the maximum length is used. 
+  
+  - When set to false, the VARCHAR type will always use the derived length.
+
+- All data types will now be displayed in lowercase to maintain compatibility with MySQL format. [#38012](https://github.com/apache/doris/pull/38012)
+
+- Multiple query statements in the same query request must now be separated by semicolons. [#38670](https://github.com/apache/doris/pull/38670)
+
+### Query Execution
+
+- The default number of parallel tasks after shuffle operations in the cluster is set to 100, which will improve query stability and concurrent processing capability in large clusters. [#38196](https://github.com/apache/doris/pull/38196)
+
+### Storage
+
+- The default value of `trash_file_expire_time_sec` has been changed from 86400 seconds to 0 seconds, which means that if files are deleted by mistake and the FE trash is cleared, the data cannot be recovered.
+
+- The table attribute `enable_mow_delete_on_delete_predicate` (introduced in version 3.0.0) has been renamed to `enable_mow_light_delete`.
+
+- Explicit transactions are now prohibited from performing delete operations on tables with written data.
+
+- Heavy schema change operations are prohibited on tables with auto-increment fields.
+
+
+
+## New Features
+
+### Job Scheduling
+
+- Optimized the execution logic of internal scheduling jobs, decoupling the strong association between start time and immediate execution parameters. Now, tasks can be created with a specified start time or selected for immediate execution, without conflict, enhancing scheduling flexibility. [#36805](https://github.com/apache/doris/pull/36805)
+
+### Compute-Storage Decoupled
+
+- Supports dynamic modification of the upper limit for file cache usage. [#37484](https://github.com/apache/doris/pull/37484)
+
+- Recycler now supports object storage rate limiting and server-side rate limiting retry functionality. [#37663](https://github.com/apache/doris/pull/37663) [#37680](https://github.com/apache/doris/pull/37680)
+
+### Lakehouse
+
+- Added the session variable `serde_dialect` to set the output format for complex types. [#37039](https://github.com/apache/doris/pull/37039)
+
+- SQL interception now supports external tables.
+
+  - For more information, refer to the documentation on  [SQL Interception](https://doris.apache.org/docs/admin-manual/query-admin/sql-interception).
+
+- Insert overwrite now supports Iceberg tables. [#37191](https://github.com/apache/doris/pull/37191)
+
+### Asynchronous Materialized Views
+
+- Supports partition roll-up and build at the hourly level. [#37678](https://github.com/apache/doris/pull/37678)
+
+- Supports atomic replacement of asynchronous materialized view definition statements. [#36749](https://github.com/apache/doris/pull/36749)
+
+- Transparent rewriting now supports Insert statements. [#38115](https://github.com/apache/doris/pull/38115)
+
+- Transparent rewriting now supports the VARIANT type. [#37929](https://github.com/apache/doris/pull/37929)
+
+### Query Execution
+
+- The group concat function now supports DISTINCT and ORDER BY options. [#38744](https://github.com/apache/doris/pull/38744)
+
+### Semi-Structured Data Management
+
+- The ES Catalog now maps `nested` or `object` types in Elasticsearch to the JSON type in Doris. [#37101](https://github.com/apache/doris/pull/37101)
+
+- Added the `MULTI_MATCH` function, which supports matching keywords across multiple fields and can leverage inverted indexes to accelerate searches. [#37722](https://github.com/apache/doris/pull/37722)
+
+- Added the `explode_json_object` function, which can unfold objects in JSON data into multiple rows. [#36887](https://github.com/apache/doris/pull/36887)
+
+- Inverted indexes now support memtable advancement, requiring index construction only once during multi-replica writes, reducing CPU consumption and improving performance. [#35891](https://github.com/apache/doris/pull/35891)
+
+- Added `MATCH_PHRASE` support for positive slop, e.g., `msg MATCH_PHRASE 'a b 2+'` can match instances containing words a and b with a slop of no more than two, and a preceding b; regular slop without the final `+` does not guarantee this order. [#36356](https://github.com/apache/doris/pull/36356)
+
+### Other
+
+- Added the FE parameter `skip_audit_user_list`, where user operations specified in this configuration will not be recorded in the audit log. [#38310](https://github.com/apache/doris/pull/38310)
+
+  - For more information, refer to the documentation on [Audit Plugin](https://doris.apache.org/docs/admin-manual/audit-plugin/).

+
+In version 1.1, we realized the full vectorization of the computing layer and storage layer, and officially enabled the vectorized execution engine as a stable function. All queries are executed by the vectorized execution engine by default, and the performance is 3-5 times higher than the previous version. It increases the ability to access the external tables of Apache Iceberg and supports federated query of data in Doris and Iceberg, and expands the analysis capabilities of Apache Doris on the data lake; on the basis of the original LZ4, the ZSTD compression algorithm is added , further improves the data compression rate; fixed many performance and stability problems in previous versions, greatly improving system stability. Downloading and using is recommended.
+
+## Upgrade Notes
+
+### The vectorized execution engine is enabled by default
+
+In version 1.0, we introduced the vectorized execution engine as an experimental feature and Users need to manually enable it when executing queries by configuring the session variables through `set batch_size = 4096` and `set enable_vectorized_engine = true` .
+
+In version 1.1, we officially fully enabled the vectorized execution engine as a stable function. The session variable `enable_vectorized_engine` is set to true by default. All queries are executed by default through the vectorized execution engine.
+
+### BE Binary File Renaming
+
+BE binary file has been renamed from palo_be to doris_be . Please pay attention to modifying the relevant scripts if you used to rely on process names for cluster management and other operations.
+
+### Segment storage format upgrade
+
+The storage format of earlier versions of Apache Doris was Segment V1. In version 0.12, we had implemented Segment V2 as a new storage format, which introduced Bitmap indexes, memory tables, page cache, dictionary compression, delayed materialization and many other features. Starting from version 0.13, the default storage format for newly created tables is Segment V2, while maintaining compatibility with the Segment V1 format.
+
+In order to ensure the maintainability of the code structure and reduce the additional learning and development costs caused by redundant historical codes, we have decided to no longer support the Segment v1 storage format from the next version. It is expected that this part of the code will be deleted in the Apache Doris 1.2 version.
+
+### Normal Upgrade
+
+For normal upgrade operations, you can perform rolling upgrades according to the cluster upgrade documentation on the official website.
+
+[https://doris.apache.org//docs/admin-manual/cluster-management/upgrade](https://doris.apache.org//docs/admin-manual/cluster-management/upgrade)
+
+## Features
+
+### Support random distribution of data [experimental]
+
+In some scenarios (such as log data analysis), users may not be able to find a suitable bucket key to avoid data skew, so the system needs to provide additional distribution methods to solve the problem.
+
+Therefore, when creating a table you can set `DISTRIBUTED BY random BUCKETS number`to use random distribution, the data will be randomly written to a single tablet when importing to reduce the data fanout during the loading process. And reduce resource overhead and improve system stability.
+
+### Support for creating Iceberg external tables[experimental]
+
+Iceberg external tables provide Apache Doris with direct access to data stored in Iceberg. Through Iceberg external tables, federated queries on data stored in local storage and Iceberg can be implemented, which saves tedious data loading work, simplifies the system architecture for data analysis, and performs more complex analysis operations.
+
+In version 1.1, Apache Doris supports creating Iceberg external tables and querying data, and supports automatic synchronization of all table schemas in the Iceberg database through the REFRESH command.
+
+### Added ZSTD compression algorithm
+
+At present, the data compression method in Apache Doris is uniformly specified by the system, and the default is LZ4. For some scenarios that are sensitive to data storage costs, the original data compression ratio requirements cannot be met.
+
+In version 1.1, users can set "compression"="zstd" in the table properties to specify the compression method as ZSTD when creating a table. In the 25GB 110 million lines of text log test data, the highest compression rate is nearly 10 times, which is 53% higher than the original compression rate, and the speed of reading data from disk and decompressing it is increased by 30%.
+
+## Improvements
+
+### More comprehensive vectorization support
+
+In version 1.1, we implemented full vectorization of the compute and storage layers, including:
+
+Implemented vectorization of all built-in functions
+
+The storage layer implements vectorization and supports dictionary optimization for low-cardinality string columns
+
+Optimized and resolved numerous performance and stability issues with the vectorization engine.
+
+We tested the performance of Apache Doris version 1.1 and version 0.15 on the SSB and TPC-H standard test datasets:
+
+On all 13 SQLs in the SSB test data set, version 1.1 is better than version 0.15, and the overall performance is improved by about 3 times, which solves the problem of performance degradation in some scenarios in version 1.0;
+
+On all 22 SQLs in the TPC-H test data set, version 1.1 is better than version 0.15, the overall performance is improved by about 4.5 times, and the performance of some scenarios is improved by more than ten times;

+
+### Compaction logic optimization and real-time guarantee
+
+In Apache Doris, each commit will generate a data version. In high concurrent write scenarios, -235 errors are prone to occur due to too many data versions and untimely compaction, and query performance will also decrease accordingly.
+
+In version 1.1, we introduced QuickCompaction, which will actively trigger compaction when the data version increases. At the same time, by improving the ability to scan fragment metadata, it can quickly find fragments with too many data versions and trigger compaction. Through active triggering and passive scanning, the real-time problem of data merging is completely solved.
+
+At the same time, for high-frequency small file cumulative compaction, the scheduling and isolation of compaction tasks is implemented to prevent the heavyweight base compaction from affecting the merging of new data.
+
+Finally, for the merging of small files, the strategy of merging small files is optimized, and the method of gradient merging is adopted. Each time the files participating in the merging belong to the same data magnitude, it prevents versions with large differences in size from merging, and gradually merges hierarchically. , reducing the number of times a single file participates in merging, which can greatly save the CPU consumption of the system.
+
+When the data upstream maintains a write frequency of 10w per second (20 concurrent write tasks, 5000 rows per job, and checkpoint interval of 1s), version 1.1 behaves as follows:
+
+-   Quick data consolidation: Tablet version remains below 50 and compaction score is stable. Compared with the -235 problem that frequently occurred during high concurrent writing in the previous version, the compaction merge efficiency has been improved by more than 10 times.
+
+-   Significantly reduced CPU resource consumption: The strategy has been optimized for small file Compaction. In the above scenario of high concurrent writing, CPU resource consumption is reduced by 25%;
+
+-   Stable query time consumption: The overall orderliness of data is improved, and the fluctuation of query time consumption is greatly reduced. The query time consumption during high concurrent writing is the same as that of only querying, and the query performance is improved by 3-4 times compared with the previous version.
+
+### Read efficiency optimization for Parquet and ORC files
+
+By adjusting arrow parameters, arrow's multi-threaded read capability is used to speed up Arrow's reading of each row_group, and it is modified to SPSC model to reduce the cost of waiting for the network through prefetching. After optimization, the performance of Parquet file import is improved by 4 to 5 times.
+
+### Safer metadata Checkpoint
+
+By double-checking the image files generated after the metadata checkpoint and retaining the function of historical image files, the problem of metadata corruption caused by image file errors is solved.
+
+## Bugfix
+
+### Fix the problem that the data cannot be queried due to the missing data version.(Serious)
+
+This issue was introduced in version 1.0 and may result in the loss of data versions for multiple replicas.
+
+### Fix the problem that the resource isolation is invalid for the resource usage limit of loading tasks (Moderate)
+
+In 1.1, the broker load and routine load will use Backends with specified resource tags to do the load.
+
+### Use HTTP BRPC to transfer network data packets over 2GB (Moderate)
+
+In the previous version, when the data transmitted between Backends through BRPC exceeded 2GB,
+it may cause data transmission errors.
+
+## Others
+
+### Disabling Mini Load
+
+The `/_load` interface is disabled by default, please use `the /_stream_load` interface uniformly.
+Of course, you can re-enable it by turning off the FE configuration item `disable_mini_load`.
+
+The Mini Load interface will be completely removed in version 1.2.
+
+### Completely disable the SegmentV1 storage format
+
+Data in SegmentV1 format is no longer allowed to be created. Existing data can continue to be accessed normally.
+You can use the `ADMIN SHOW TABLET STORAGE FORMAT` statement to check whether the data in SegmentV1 format
+still exists in the cluster. And convert to SegmentV2 through the data conversion command
+
+Access to SegmentV1 data will no longer be supported in version 1.2.
+
+### Limit the maximum length of String type
+
+In previous versions, String types were allowed a maximum length of 2GB.
+In version 1.1, we will limit the maximum length of the string type to 1MB. Strings longer than this length cannot be written anymore.
+At the same time, using the String type as a partitioning or bucketing column of a table is no longer supported.
+
+The String type that has been written can be accessed normally.
+
+### Fix fastjson related vulnerabilities
+
+Update to Canal version to fix fastjson security vulnerability.
+
+### Added `ADMIN DIAGNOSE TABLET` command
+
+Used to quickly diagnose problems with the specified tablet.

+## Features
+
+### Support ODBC Sink in Vectorized Engine.
+
+This feature is enabled in non-vectorized engine but it is missed in vectorized engine in 1.1. So that we add back this feature in 1.1.1.
+
+### Simple Memtracker for Vectorized Engine.
+
+There is no memtracker in BE for vectorized engine in 1.1, so that the memory is out of control and cause OOM. In 1.1.1, a simple memtracker is added to BE and could control the memory and cancel the query when memory exceeded.
+
+## Improvements
+
+### Cache decompressed data in page cache.
+
+Some data is compressed using bitshuffle and it costs a lot of time to decompress it during query. In 1.1.1, doris will decompress the data that encoded by bitshuffle to accelerate query and we find it could reduce 30% latency for some query in ssb-flat.
+
+## Bug Fix
+
+### Fix the problem that could not do rolling upgrade from 1.0.(Serious)
+
+This issue was introduced in version 1.1 and may cause BE core when upgrade BE but not upgrade FE.
+
+If you encounter this problem, you can try to fix it with [#10833](https://github.com/apache/doris/pull/10833).
+
+### Fix the problem that some query not fall back to non-vectorized engine, and BE will core.
+
+Currently, vectorized engine could not deal with all sql queries and some queries (like left outer join) will use non-vectorized engine to run. But there are some cases not covered in 1.1. And it will cause be crash.
+
+### Compaction not work correctly and cause -235 Error.
+
+One rowset multi segments in uniq key compaction, segments rows will be merged in generic_iterator but merged_rows not increased. Compaction will failed in check_correctness, and make a tablet with too much versions which lead to -235 load error.
+
+### Some segment fault cases during query.

+
+# Upgrade Notes
+
+PageCache and ChunkAllocator are disabled by default to reduce memory usage and can be re-enabled by modifying the configuration items `disable_storage_page_cache` and `chunk_reserved_bytes_limit`.
+
+Storage Page Cache and Chunk Allocator cache user data chunks and memory preallocation, respectively.
+
+These two functions take up a certain percentage of memory and are not freed. This part of memory cannot be flexibly allocated, which may lead to insufficient memory for other tasks in some scenarios, affecting system stability and availability. Therefore, we disabled these two features by default in version 1.1.3.
+
+However, in some latency-sensitive reporting scenarios, turning off this feature may lead to increased query latency. If you are worried about the impact of this feature on your business after upgrade, you can add the following parameters to be.conf to keep the same behavior as the previous version.
+
+```
+disable_storage_page_cache=false
+chunk_reserved_bytes_limit=10%
+```
+
+* ``disable_storage_page_cache``: Whether to disable Storage Page Cache. version 1.1.2 (inclusive), the default is false, i.e., on. version 1.1.3 defaults to true, i.e., off.
+* `chunk_reserved_bytes_limit`: Chunk allocator reserved memory size. 1.1.2 (and earlier), the default is 10% of the overall memory. 1.1.3 version default is 209715200 (200MB).

+
+# Behavior Changes
+
+When alias name is same as the original column name like "select year(birthday) as birthday" and use it in group by, order by , having clause, doris's behavior is different from MySQL in the past. In this release, we make it follow MySQL's behavior. Group by and having clause will use original column at first and order by will use alias first. It maybe a litter confuse here so there is a simple advice here, you'd better not use an alias the same as original column name.
+

+# Feature
+## Highlight
+
+1. Full Vectorizied-Engine support, greatly improved performance
+
+	In the standard ssb-100-flat benchmark, the performance of 1.2 is 2 times faster than that of 1.1; in complex TPCH 100 benchmark, the performance of 1.2 is 3 times faster than that of 1.1.
+
+2. Merge-on-Write Unique Key
+
+	Support Merge-On-Write on Unique Key Model. This mode marks the data that needs to be deleted or updated when the data is written, thereby avoiding the overhead of Merge-On-Read when querying, and greatly improving the reading efficiency on the updateable data model.
+
+3. Multi Catalog
+
+	The multi-catalog feature provides Doris with the ability to quickly access external data sources for access. Users can connect to external data sources through the `CREATE CATALOG` command. Doris will automatically map the library and table information of external data sources. After that, users can access the data in these external data sources just like accessing ordinary tables. It avoids the complicated operation that the user needs to manually establish external mapping for each table.
+    
+    Currently this feature supports the following data sources:
+    
+    1. Hive Metastore: You can access data tables including Hive, Iceberg, and Hudi. It can also be connected to data sources compatible with Hive Metastore, such as Alibaba Cloud's DataLake Formation. Supports data access on both HDFS and object storage.
+    2. Elasticsearch: Access ES data sources.
+    3. JDBC: Access MySQL through the JDBC protocol.
+    
+    Documentation: https://doris.apache.org//docs/dev/lakehouse/multi-catalog)
+
+    > Note: The corresponding permission level will also be changed automatically, see the "Upgrade Notes" section for details.
+    
+4. Light table structure changes
+
+In the new version, it is no longer necessary to change the data file synchronously for the operation of adding and subtracting columns to the data table, and only need to update the metadata in FE, thus realizing the millisecond-level Schema Change operation. Through this function, the DDL synchronization capability of upstream CDC data can be realized. For example, users can use Flink CDC to realize DML and DDL synchronization from upstream database to Doris.
+
+Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Definition-Statements/Create/CREATE-TABLE
+
+When creating a table, set `"light_schema_change"="true"` in properties.
+
+5. JDBC facade
+
+	Users can connect to external data sources through JDBC. Currently supported:
+
+	  - MySQL
+	  - PostgreSQL
+	  - Oracle
+	  - SQL Server
+	  - Clickhouse
+
+	Documentation: [https://doris.apache.org/en/docs/dev/lakehouse/multi-catalog/jdbc](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc/)
+
+	> Note: The ODBC feature will be removed in a later version, please try to switch to the JDBC.
+
+6. JAVA UDF
+
+	Supports writing UDF/UDAF in Java, which is convenient for users to use custom functions in the Java ecosystem. At the same time, through technologies such as off-heap memory and Zero Copy, the efficiency of cross-language data access has been greatly improved.
+
+	Document: https://doris.apache.org//docs/dev/ecosystem/udf/java-user-defined-function
+
+	Example: https://github.com/apache/doris/tree/master/samples/doris-demo
+	
+7. Remote UDF
+
+	Supports accessing remote user-defined function services through RPC, thus completely eliminating language restrictions for users to write UDFs. Users can use any programming language to implement custom functions to complete complex data analysis work.
+
+	Documentation: https://doris.apache.org//docs/ecosystem/udf/remote-user-defined-function
+
+	Example: https://github.com/apache/doris/tree/master/samples/doris-demo
+        
+8. More data types support
+
+	- Array type
+
+		Array types are supported. It also supports nested array types. In some scenarios such as user portraits and tags, the Array type can be used to better adapt to business scenarios. At the same time, in the new version, we have also implemented a large number of data-related functions to better support the application of data types in actual scenarios.
+
+	Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Types/ARRAY
+
+	Related functions: https://doris.apache.org//docs/dev/sql-manual/sql-functions/array-functions/array_max
+        
+	- Jsonb type
+
+		Support binary Json data type: Jsonb. This type provides a more compact json encoding format, and at the same time provides data access in the encoding format. Compared with json data stored in strings, it is several times newer and can be improved.
+
+	Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Types/JSONB
+
+	Related functions: https://doris.apache.org//docs/dev/sql-manual/sql-functions/json-functions/jsonb_parse
+          
+	- Date V2
+	
+		Sphere of influence:
+
+		1. The user needs to specify datev2 and datetimev2 when creating the table, and the date and datetime of the original table will not be affected.
+		2. When datev2 and datetimev2 are calculated with the original date and datetime (for example, equivalent connection), the original type will be cast into a new type for calculation
+		3. The example is in the documentation
+
+		Documentation: https://doris.apache.org/docs/1.2/sql-manual/sql-reference/Data-Types/DATEV2
+	 
+	 
+## More
+
+1. A new memory management framework
+
+	Documentation: https://doris.apache.org//docs/dev/admin-manual/maint-monitor/memory-management/memory-tracker
+
+2. Table Valued Function
+
+	Doris implements a set of Table Valued Function (TVF). TVF can be regarded as an ordinary table, which can appear in all places where "table" can appear in SQL.
+
+	For example, we can use S3 TVF to implement data import on object storage:
+
+	```
+	insert into tbl select * from s3("s3://bucket/file.*", "ak" = "xx", "sk" = "xxx") where c1 > 2;
+	```
+
+	Or directly query data files on HDFS:
+	
+	```
+	insert into tbl select * from hdfs("hdfs://bucket/file.*") where c1 > 2;
+	```
+	
+	TVF can help users make full use of the rich expressiveness of SQL and flexibly process various data.
+

+    
+    https://doris.apache.org//docs/dev/sql-manual/sql-functions/table-functions/hdfs
+        
+3. A more convenient way to create partitions
+
+	Support for creating multiple partitions within a time range via the `FROM TO` command.
+
+4. Column renaming
+
+	For tables with Light Schema Change enabled, column renaming is supported.
+
+	Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Definition-Statements/Alter/ALTER-TABLE-RENAME
+	
+5. Richer permission management
+
+	- Support row-level permissions
+	
+		Row-level permissions can be created with the `CREATE ROW POLICY` command.
+	
+		Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Definition-Statements/Create/CREATE-POLICY
+	
+	- Support specifying password strength, expiration time, etc.
+	
+	- Support for locking accounts after multiple failed logins.
+	
+		Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Account-Management-Statements/ALTER-USER
+
+6. Import
+
+	- CSV import supports csv files with header.
+	
+		Search for `csv_with_names` in the documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Manipulation-Statements/Load/STREAM-LOAD/
+	
+	- Stream Load adds `hidden_columns`, which can explicitly specify the delete flag column and sequence column.
+	
+		Search for `hidden_columns` in the documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Manipulation-Statements/Load/STREAM-LOAD

+# Upgrade Notice
+
+## Known Issues
+
+- Use JDK11 will cause BE crash, please use JDK8 instead.
+
+## Behavior Changed
+
+- Permission level changes
+
+	Because the catalog level is introduced, the corresponding user permission level will also be changed automatically. The rules are as follows:
+	
+	- GlobalPrivs and ResourcePrivs remain unchanged
+	- Added CatalogPrivs level.
+	- The original DatabasePrivs level is added with the internal prefix (indicating the db in the internal catalog)
+	- Add the internal prefix to the original TablePrivs level (representing tbl in the internal catalog)
+
+- In GroupBy and Having clauses, match on column names in preference to aliases. (#14408)
+
+- Creating columns starting with `mv_` is no longer supported. `mv_` is a reserved keyword in materialized views (#14361)
+
+- Removed the default limit of 65535 rows added by the order by statement, and added the session variable `default_order_by_limit` to configure this limit. (#12478)
+
+- In the table generated by "Create Table As Select", all string columns use the string type uniformly, and no longer distinguish varchar/char/string (#14382)
+
+- In the audit log, remove the word `default_cluster` before the db and user names. (#13499) (#11408)
+
+- Add sql digest field in audit log (#8919)
+
+- The union clause always changes the order by logic. In the new version, the order by clause will be executed after the union is executed, unless explicitly associated by parentheses. (#9745)
+
+- During the decommission operation, the tablet in the recycle bin will be ignored to ensure that the decomission can be completed. (#14028)
+
+- The returned result of Decimal will be displayed according to the precision declared in the original column, or according to the precision specified in the cast function. (#13437)
+
+- Changed column name length limit from 64 to 256 (#14671)
+
+- Changes to FE configuration items
+
+  - The `enable_vectorized_load` parameter is enabled by default. (#11833)
+
+  - Increased `create_table_timeout` value. The default timeout for table creation operations will be increased. (#13520)
+
+  - Modify `stream_load_default_timeout_second` default value to 3 days.
+
+  - Modify the default value of `alter_table_timeout_second` to one month.
+
+  - Increase the parameter `max_replica_count_when_schema_change` to limit the number of replicas involved in the alter job, the default is 100000. (#12850)
+
+  - Add `disable_iceberg_hudi_table`. The iceberg and hudi appearances are disabled by default, and the multi catalog function is recommended. (#13932)
+
+- Changes to BE configuration items
+
+  - Removed `disable_stream_load_2pc` parameter. 2PC's stream load can be used directly. (#13520)
+
+  - Modify `tablet_rowset_stale_sweep_time_sec` from 1800 seconds to 300 seconds.
+
+  - Redesigned configuration item name about compaction (#13495)
+
+  - Revisited parameter about memory optimization (#13781)
+
+- Session variable changes
+
+   - Modify the variable `enable_insert_strict` to true by default. This will cause some insert operations that could be executed before, but inserted illegal values, to no longer be executed. (11866)
+
+   - Modified variable `enable_local_exchange` to default to true (#13292)
+
+   - Default data transmission via lz4 compression, controlled by variable `fragment_transmission_compression_codec` (#11955)
+
+   - Add `skip_storage_engine_merge` variable for debugging unique or agg model data (#11952)
+    
+     Documentation: https://doris.apache.org//docs/dev/advanced/variables
+
+- The BE startup script will check whether the value is greater than 200W through `/proc/sys/vm/max_map_count`. Otherwise, the startup fails. (#11052)
+
+- Removed mini load interface (#10520)
+
+- FE Metadata Version
+
+	FE Meta Version changed from 107 to 114, and cannot be rolled back after upgrading.
+	
+## During Upgrade
+
+1. Upgrade preparation
+  
+   - Need to replace: lib, bin directory (start/stop scripts have been modified)
+  
+   - BE also needs to configure JAVA_HOME, and already supports JDBC Table and Java UDF.
+  
+   - The default JVM Xmx parameter in fe.conf is changed to 8GB.
+
+2. Possible errors during the upgrade process
+  
+   - The repeat function cannot be used and an error is reported: `vectorized repeat function cannot be executed`, you can turn off the vectorized execution engine before upgrading. (#13868)
+  
+   - schema change fails with error: `desc_tbl is not set. Maybe the FE version is not equal to the BE` (#13822)
+  
+   - Vectorized hash join cannot be used and an error will be reported. `vectorized hash join cannot be executed`. You can turn off the vectorized execution engine before upgrading. (#13753)
+
+	The above errors will return to normal after a full upgrade.
+	
+## Performance Impact
+
+- By default, JeMalloc is used as the memory allocator of the new version BE, replacing TcMalloc (#13367)
+
+- The batch size in the tablet sink is modified to be at least 8K. (#13912)
+
+- Disable chunk allocator by default (#13285)
+
+## Api change
+
+- BE's http api error return information changed from `{"status": "Fail", "msg": "xxx"}` to more specific ``{"status": "Not found", "msg": "Tablet not found. tablet_id=1202"}``(#9771)
+
+- In `SHOW CREATE TABLE`, the content of comment is changed from double quotes to single quotes (#10327)
+
+- Support ordinary users to obtain query profile through http command. (#14016)
+Documentation: https://doris.apache.org//docs/dev/admin-manual/http-actions/fe/manager/query-profile-action
+
+- Optimized the way to specify the sequence column, you can directly specify the column name. (#13872)
+Documentation: https://doris.apache.org//docs/dev/data-operate/update-delete/sequence-column-manual
+
+- Increase the space usage of remote storage in the results returned by `show backends` and `show tablets` (#11450)
+

+
+Currently, Jdbc Catalog only support to use 5.x version of JDBC jar package to connect another Doris database. If you use 8.x version of JDBC jar package, the data type of column may not be matched.
+
+Reference: [https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc/#doris](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc/#doris)
+
+- Support to synchronize only the specified database through the `only_specified_database` attribute.
+
+- Support synchronizing table names in the form of lowercase through `lower_case_table_names` to solve the problem of case sensitivity of table names.

+
+### Hive Catalog
+
+- Support Hive table default partition `_HIVE_DEFAULT_PARTITION_`.
+
+- Hive Metastore metadata automatic synchronization supports notification event in compressed format.
+
+### Dynamic Partition Improvement
+
+- Dynamic partition supports specifying the `storage_medium` parameter to control the storage medium of the newly added partition.
+
+Reference: [https://doris.apache.org/docs/dev/advanced/partition/dynamic-partition](https://doris.apache.org/docs/dev/advanced/partition/dynamic-partition)
+
+
+### Optimize BE's Threading Model
+
+- Optimize BE's threading model to avoid stability problems caused by frequent thread creation and destroy.

+
+# Behavior Changed
+
+- For `DateV2`/`DatetimeV2` and `DecimalV3` type, in the results of `DESCRIBLE` and `SHOW CREATE TABLE` statements, they will no longer be displayed as `DateV2`/`DatetimeV2` or `DecimalV3`, but directly displayed as `Date`/`Datetime` or `Decimal`.
+
+	- This change is for compatibility with some BI tools. If you want to see the actual type of the column, you can check it with the `DESCRIBE ALL` statement.
+
+- When querying tables in the `information_schema` database, the meta information(database, table, column, etc.) in the external catalog is no longer returned by default.
+
+	- This change avoids the problem that the `information_schema` database cannot be queried due to the connection problem of some external catalog, so as to solve the problem of using some BI tools with Doris. It can be controlled by the FE configuration  `infodb_support_ext_catalog`, and the default value is `false`, that is, the meta information of external catalog will not be returned.
+
+# Improvement
+
+### JDBC Catalog
+
+- Supports connecting to Trino/Presto via JDBC Catalog
+
+​        Refer to: [https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino)
+
+- JDBC Catalog connects to Clickhouse data source and supports Array type mapping
+
+​        Refer to: [https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#clickhouse](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#clickhouse)
+
+### Spark Load 
+
+- Spark Load supports Resource Manager HA related configuration
+
+​        Refer to: https://github.com/apache/doris/pull/15000
+
+## Bug Fixes
+
+- Fixed several connectivity issues with Hive Catalog.

+
+In version 1.2.5, the Doris team has fixed nearly 210 issues or performance improvements since the release of version 1.2.4. At the same time, version 1.2.5 is also an iterative version of version 1.2.4, which has higher stability. It is recommended that all users upgrade to this version.
+
+# Behavior Changed
+
+- The `start_be.sh` script will check that the maximum number of file handles in the system must be greater than or equal to 65536, otherwise the startup will fail.
+
+- The BE configuration item `enable_quick_compaction` is set to true by default. The Quick Compaction is enabled by default. This feature is used to optimize the problem of small files in the case of large batch import.
+
+- After modifying the dynamic partition attribute of the table, it will no longer take effect immediately, but wait for the next task scheduling of the dynamic partition table to avoid some deadlock problems.
+
+# Improvement
+
+- Optimize the use of bthread and pthread to reduce the RPC blocking problem during the query process.
+
+- A button to download Profile is added to the Profile page of the FE web UI.
+
+- Added FE configuration `recover_with_skip_missing_version`, which is used to query to skip the problematic replica under certain failure conditions.
+
+- The row-level permission function supports external Catalog.
+
+- Hive Catalog supports automatic refreshing of kerberos tickets on the BE side without manual refreshing.
+
+- JDBC Catalog supports tables under the MySQL/ClickHouse system database (`information_schema`).
+
+# Bug Fixes
+
+- Fixed the problem of incorrect query results caused by low-cardinality column optimization
+
+- Fixed several authentication and compatibility issues accessing HDFS.
+
+- Fixed several issues with float/double and decimal types.
+
+- Fixed several issues with date/datetimev2 types.
+
+- Fixed several query execution and planning issues.
+
+- Fixed several issues with JDBC Catalog.
+
+- Fixed several query-related issues with Hive Catalog, and Hive Metastore metadata synchronization issues.
+
+- Fix the problem that the result of `SHOW LOAD PROFILE` statement is incorrect.
+
+- Fixed several memory related issues.
+
+- Fixed several issues with `CREATE TABLE AS SELECT` functionality.
+
+- Fix the problem that the jsonb type causes BE to crash on CPU that do not support avx2.
+
+- Fixed several issues with dynamic partitions.
+
+- Fixed several issues with TOPN query optimization.
+
+- Fixed several issues with the Unique Key Merge-on-Write table model.

+## **A 10 Times Performance Increase**
+
+In SSB-Flat and TPC-H benchmarking, Apache Doris 2.0.0 delivered **over 10-time faster query performance** compared to an early version of Apache Doris.
+
+![](/images/release-note-2.0.0-1.png)
+
+This is realized by the introduction of a smarter query optimizer, inverted index, a parallel execution model, and a series of new functionalities to support high-concurrency point queries.
+
+### A smarter query optimizer
+
+The brand new query optimizer, Nereids, has a richer statistical base and adopts the Cascades framework. It is capable of self-tuning in most query scenarios and supports all 99 SQLs in TPC-DS, so users can expect high performance without any fine-tuning or SQL rewriting.
+
+TPC-H tests showed that Nereids, with no human intervention, outperformed the old query optimizer by a wide margin. Over 100 users have tried Apache Doris 2.0.0 in their production environment and the vast majority of them reported huge speedups in query execution.

+Nereids is enabled by default in Apache Doris 2.0.0: `SET enable_nereids_planner=true`. Nereids collects statistical data by calling the Analyze command.
+
+### Inverted Index
+
+In Apache Doris 2.0.0, we introduced inverted index to better support fuzzy keyword search, equivalence queries, and range queries.
+
+A smartphone manufacturer tested Apache Doris 2.0.0 in their user behavior analysis scenarios. With inverted index enabled, v2.0.0 was able to finish the queries within milliseconds and maintain stable performance as the query concurrency level went up. In this case, it is 5 to 90 times faster than its old version.

+
+### 20 times higher concurrency capability
+
+In scenarios like e-commerce order queries and express tracking, a huge number of end data users search for a certain data record simultaneously. These are what we call high-concurrency point queries, which can bring huge pressure on the system. A traditional solution is to introduce Key-Value stores like Apache HBase for such queries, and Redis as a cache layer to ease the burden, but that means redundant storage and higher maintenance costs.
+
+For a column-oriented DBMS like Apache Doris, the I/O usage of point queries will be multiplied. We need neater execution. Thus, on the basis of columnar storage, we added row storage format and row cache to increase row reading efficiency, short-circuit plans to speed up data retrieval, and prepared statements to reduce frontend overheads.
+
+After these optimizations, Apache Doris 2.0 reached a concurrency level of **30,000 QPS per node** on YCSB on a 16 Core 64G cloud server with 4×1T hard drives, representing an improvement of **20 times** compared to its older version. This makes Apache Doris a good alternative to HBase in high-concurrency scenarios, so that users don't need to endure extra maintenance costs and redundant storage brought by complicated tech stacks.

+
+### A self-adaptive parallel execution model
+
+Apache 2.0 brought in a Pipeline execution model for higher efficiency and stability in hybrid analytic workloads. In this model, the execution of queries is driven by data. The blocking operators in all query execution processes are split into pipelines. Whether a pipeline gets an execution thread depends on whether its relevant data is ready. This enables asynchronous blocking operations and more flexible system resource management. Also, this improves CPU efficiency as the system doesn't have to create and destroy threads that much.
+
+Doc: https://doris.apache.org/docs/dev/query-acceleration/pipeline-execution-engine/
+
+**How to enable the Pipeline execution model**
+
+- The Pipeline execution engine is enabled by default in Apache Doris 2.0: `Set enable_pipeline_engine = true`.
+- `parallel_pipeline_task_num` represents the number of pipeline tasks that are parallelly executed in SQL queries. The default value of it is `0`, which means Apache Doris will automatically set the concurrency level to half the number of CPUs in each backend node. Users can change this value as they need it. 
+- For those who are upgrading to Apache Doris 2.0 from an older version, it is recommended to set the value of `parallel_pipeline_task_num` to that of `parallel_fragment_exec_instance_num` in the old version.
+
+## A Unified Platform for Multiple Analytic Workloads
+
+Apache Doris has been pushing its boundaries. Starting as an OLAP engine for reporting, it is now a data warehouse capable of ETL/ELT and more. Version 2.0 is making advancements in its log analysis and data lakehousing capabilities.  
+
+### A 10 times more cost-effective log analysis solution
+
+Apache Doris 2.0.0 provides native support for semi-structured data. In addition to JSON and Array, it now supports a complex data type: Map. Based on Light Schema Change, it also supports Schema Evolution, which means you can adjust the schema as your business changes. You can add or delete fields and indexes, and change the data types for fields. As we introduced inverted index and a high-performance text analysis algorithm into it, it can execute full-text search and dimensional analysis of logs more efficiently. With faster data writing and query speed and lower storage cost, it is 10 times more cost-effective than the common log analytic solution within the industry.
+
+![](/images/release-note-2.0.0-4.png)
+
+### Enhanced data lakehousing capabilities
+
+In Apache Doris 1.2, we introduced Multi-Catalog to allow for auto-mapping and auto-synchronization of data from heterogeneous sources. In version 2.0.0, we extended the list of data sources supported and optimized Doris for based on users' needs in production environment.
+
+![](/images/release-note-2.0.0-5.png)
+
+Apache Doris 2.0.0 supports dozens of data sources including Hive, Hudi, Iceberg, Paimon, MaxCompute, Elasticsearch, Trino, ClickHouse, and almost all open lakehouse formats. It also supports snapshot queries on Hudi Copy-on-Write tables and read optimized queries on Hudi Merge-on-Read tables. It allows for authorization of Hive Catalog using Apache Ranger, so users can reuse their existing privilege control system. Besides, it supports extensible authorization plug-ins to enable user-defined authorization methods for any catalog. 
+
+TPC-H benchmark tests showed that Apache Doris 2.0.0 is 3~5 times faster than Presto/Trino in queries on Hive tables. This is realized by all-around optimizations (in small file reading, flat table reading, local file cache, ORC/Parquet file reading, Compute Nodes, and information collection of external tables) finished in this development cycle and the distributed execution framework, vectorized execution engine, and query optimizer of Apache Doris. 
+
+![](/images/release-note-2.0.0-6.png)
+
+All this gives Apache Doris 2.0.0 an edge in data lakehousing scenarios. With Doris, you can do incremental or overall synchronization of multiple upstream data sources in one place, and expect much higher data query performance than other query engines. The processed data can be written back to the sources or provided for downstream systems. In this way, you can make Apache Doris your unified data analytic gateway.
+
+## Efficient Data Update
+
+Data update is important in real-time analysis, since users want to always be accessible to the latest data, and be able to update data flexibly, such as updating a row or just a few columns, batching updating or deleting their specified data, or even overwriting a whole data partition.
+
+Efficient data updating has been another hill to climb in data analysis. Apache Hive only supports updates on the partition level, while Hudi and Iceberg do better in low-frequency batch updates instead of real-time updates due to their Merge-on-Read and Copy-on-Write implementations.
+
+As for data updating, Apache Doris 2.0.0 is capable of:
+
+- **Faster data writing**: In the pressure tests with an online payment platform, under 20 concurrent data writing tasks, Doris reached a writing throughput of 300,000 records per second and maintained stability throughout the over 10-hour continuous writing process.
+- **Partial column update**: Older versions of Doris implements partial column update by `replace_if_not_null` in the Aggregate Key model. In 2.0.0, we enable partial column updates in the Unique Key model. That means you can directly write data from multiple source tables into a flat table, without having to concatenate them into one output stream using Flink before writing. This method avoids a complicated processing pipeline and the extra resource consumption. You can simply specify the columns you need to update.
+- **Conditional update and deletion**: In addition to the simple Update and Delete operations, we realize complicated conditional updates and deletes operations on the basis of Merge-on-Write. 
+
+## Faster, Stabler, and Smarter Data Writing
+
+### Higher speed in data writing
+
+As part of our continuing effort to strengthen the real-time analytic capability of Apache Doris, we have improved the end-to-end real-time data writing capability of version 2.0.0. Benchmark tests reported higher throughput in various writing methods:
+
+- Stream Load, TPC-H 144G lineitem table, 48-bucket Duplicate table, triple-replica writing: throughput increased by 100%
+- Stream Load, TPC-H 144G lineitem table, 48-bucket Unique Key table, triple-replica writing: throughput increased by 200%
+- Insert Into Select, TPC-H 144G lineitem table, 48-bucket Duplicate table: throughput increased by 50%
+- Insert Into Select, TPC-H 144G lineitem table, 48-bucket Unique Key table: throughput increased by 150%
+
+### Greater stability in high-concurrency data writing 
+
+The sources of system instability often includes small file merging, write amplification, and the consequential disk I/O and CPU overheads. Hence, we introduced Vertical Compaction and Segment Compaction in version 2.0.0 to eliminate OOM errors in compaction and avoid the generation of too many segment files during data writing. After such improvements, Apache Doris can write data 50% faster while **using only 10% of the memory that it previously used**.

+
+### Auto-synchronization of table schema
+
+The latest Flink-Doris-Connector allows users to synchronize an entire database (such as MySQL and Oracle) to Apache Doris by one simple step. According to our test results, one single synchronization task can support the real-time concurrent writing of thousands of tables. Users no longer need to go through a complicated synchronization procedure because Apache Doris has automated the process. Changes in the upstream data schema will be automatically captured and dynamically updated to Apache Doris in a seamless manner.

+
+## A New Multi-Tenant Resource Isolation Solution
+
+The purpose of multi-tenant resource isolation is to avoid resource preemption in the case of heavy loads. For that sake, older versions of Apache Doris adopted a hard isolation plan featured by Resource Group: Backend nodes of the same Doris cluster would be tagged, and those of the same tag formed a Resource Group. As data was ingested into the database, different data replicas would be written into different Resource Groups, which will be responsible for different workloads. For example, data reading and writing will be conducted on different data tablets, so as to realize read-write separation. Similarly, you can also put online and offline business on different Resource Groups. 
+
+![](/images/release-note-2.0.0-7.png)
+
+This is an effective solution, but in practice, it happens that some Resource Groups are heavily occupied while others are idle. We want a more flexible way to reduce vacancy rate of resources. Thus, in 2.0.0, we introduce Workload Group resource soft limit.
+
+![](/images/release-note-2.0.0-8.png)
+
+The idea is to divide workloads into groups to allow for flexible management of CPU and memory resources. Apache Doris associates a query with a Workload Group, and limits the percentage of CPU and memory that a single query can use on a backend node. The memory soft limit can be configured and enabled by the user. 
+
+When there is a cluster resource shortage, the system will kill the largest memory-consuming query tasks; when there are sufficient cluster resources, once a Workload Group uses more resources than expected, the idle cluster resources will be shared among all the Workload Groups to give full play to the system memory and ensure stable execution of queries. You can also prioritize the Workload Groups in terms of resource allocation. In other words, you can decide which tasks can be assigned with adequate resources and which not.
+
+Meanwhile, we introduced Query Queue in 2.0.0. Upon Workload Group creation, you can set a maximum query number for a query queue. Queries beyond that limit will wait for execution in the queue. This is to reduce system burden under heavy workloads.
+
+## Elastic Scaling and Storage-Compute Separation
+
+When it comes to computation and storage resources, what do users want?
+
+- **Elastic scaling of computation resources**: Scale up resources quickly in peak times to increase efficiency and scale down in valley times to reduce costs.
+- **Lower storage costs**: Use low-cost storage media and separate storage from computation.
+- **Separation of workloads**: Isolate the computation resources of different workloads to avoid preemption.
+- **Unified management of data**: Simply manage catalogs and data in one place.
+
+To separate storage and computation is a way to realize elastic scaling of resources, but it demands more efforts in maintaining storage stability, which determines the stability and continuity of OLAP services. To ensure storage stability, we introduced mechanisms including cache management, computation resource management, and garbage collection.
+
+ In this respect, we divide our users into three groups after investigation:
+
+1. Users with no need for resource scaling
+2. Users requiring resource scaling, low storage costs, and workload separation from Apache Doris
+3. Users who already have a stable large-scale storage system and thus require an advanced compute-storage-separated architecture for efficient resource scaling
+
+Apache Doris 2.0 provides two solutions to address the needs of the first two types of users.
+
+1. **Compute nodes**. We introduced stateless compute nodes in version 2.0. Unlike the mix nodes, the compute nodes do not save any data and are not involved in workload balancing of data tablets during cluster scaling. Thus, they are able to quickly join the cluster and share the computing pressure during peak times. In addition, in data lakehouse analysis, these nodes will be the first ones to execute queries on remote storage (HDFS/S3) so there will be no resource competition between internal tables and external tables.
+   1.  Doc: https://doris.apache.org/docs/dev/advanced/compute_node/
+2. **Hot-cold data separation**. Hot/cold data refers to data that is frequently/seldom accessed, respectively. Generally, it makes more sense to store cold data in low-cost storage. Older versions of Apache Doris support lifecycle management of table partitions: As hot data cooled down, it would be moved from SSD to HDD. However, data was stored with multiple replicas on HDD, which was still a waste. Now, in Apache Doris 2.0, cold data can be stored in object storage, which is even cheaper and allows single-copy storage. That reduces the storage costs by 70% and cuts down the computation and network overheads that come with storage.
+   1.  Read more: https://doris.apache.org/blog/HCDS/
+
+For neater separate of computation and storage, the VeloDB team is going to contribute the Cloud Compute-Storage-Separation solution to the Apache Doris project. The performance and stability of it has stood the test of hundreds of companies in their production environment. The merging of code will be finished by October this year, and all Apache Doris users will be able to get an early taste of it in September.
+
+## Enhanced Usability
+
+Apache Doris 2.0.0 also highlights some enterprise-facing functionalities.
+
+### Support for Kubernetes Deployment
+
+Older versions of Apache Doris communicate based on IP, so any host failure in Kubernetes deployment that causes a POD IP drift will lead to cluster unavailability. Now, version 2.0 supports FQDN. That means the failed Doris nodes can recover automatically without human intervention, which lays the foundation for Kubernetes deployment and elastic scaling.  
+
+### Support for Cross-Cluster Replication (CCR)
+
+Apache Doris 2.0.0 supports cross-cluster replication (CCR). Data changes at the database/table level in the source cluster will be synchronized to the target cluster. You can choose to replicate the incremental data or the overall data. 
+
+It also supports synchronization of DDL, which means DDL statements executed by the source cluster can also by automatically replicated to the target cluster. 
+
+It is simple to configure and use CCR in Doris. Leveraging this functionality, you can implement read-write separation and multi-datacenter replication 
+
+This feature allows for higher availability of data, read/write workload separation, and cross-data-center replication more efficiently.
+
+## Behavior Change
+
+- Use rolling upgrade from 1.2-ITS to 2.0.0, and restart upgrade from preview versions of 2.0 to 2.0.0;
+- The new query optimizer (Nereids) is enabled by default: `enable_nereids_planner=true`;
+- All non-vectorized code has been removed from the system, so the `enable_vectorized_engine` parameter no long works;
+- A new parameter `enable_single_replica_compaction` has been added;
+- datev2, datetimev2, and decimalv3 are the default data types in table creation; datav1, datetimev1, and decimalv2 are not supported in table creation;
+- decimalv3 is the default data type for JDBC and Iceberg Catalog;
+- A new data type `AGG_STATE` has been added;
+- The cluster column has been removed from backend tables;
+- For better compatibility with BI tools, datev2 and datetimev2 are displayed as date and datetime when `show create table`;
+- max_openfiles and swaps checks are added to the backend startup script so inappropriate system configuration might lead to backend failure;
+- Password-free login is not allowed when accessing frontend on localhost;
+- If there is a Multi-Catalog in the system, by default, only data of the internal catalog will be displayed when querying information schema;
+- A limit has been imposed on the depth of the expression tree. The default value is 200;
+- The single quote in the return value of array string has been changed to double quote;
+- The Doris processes are renamed to DorisFE and DorisBE.
+- The functions AES and SM4 with two arguments' behaviour changed. See more informations in [relative function docs](../../sql-manual/sql-functions/encrypt-digest-functions/sm4-encrypt.md)
+
+## Embarking on the 2.0.0 Journey
+
+To make Apache Doris 2.0.0 production-ready, we invited hundreds of enterprise users to engage in the testing and optimized it for better performance, stability, and usability. In the next phase, we will continue responding to user needs with agile release planning. We plan to launch 2.0.1 in late August and 2.0.2 in September, as we keep fixing bugs and adding new features. We also plan to release an early version of 2.1 in September to bring a few long-requested capabilities to you. For example, in Doris 2.1, the Variant data type will better serve the schema-free analytic needs of semi-structured data; the multi-table materialized views will be able to simplify the data scheduling and processing link while speeding up queries; more and neater data ingestion methods will be added and nested composite data types will be realized.

+## Improvement and Optimizations
+
+- This enhancement introduces the `read_only` and `super_read_only` variables to the database system, ensuring compatibility with MySQL's read-only modes.
+
+- When the check status is not IO_ERROR, the disk path should not be added to the broken list. This ensures that only disks with actual I/O errors are marked as broken.
+
+- When performing a Create Table As Select (CTAS) operation from an external table, convert the `VARCHAR` column to `STRING` type.
+
+- Support mapping Paimon column type "ROW" to Doris type "STRUCT"
+
+- Choose disk tolerate with little skew when creating tablet
+
+- Write editlog to `set replica drop` to avoid confusing status on follower FE
+
+- Make the schema change memory space adaptive to avoid memory over limit
+
+- Inverted index 'unicode' tokenizer supports configuration to exclude stop words
+
+See the complete list of improvements and bug fixes on [GitHub](https://github.com/apache/doris/compare/2.0.9...2.0.10) .

+
+## 1 Behavior change
+
+Since the inverted index is now mature and stable, it can replace the old BITMAP INDEX. Therefore, any newly created `BITMAP INDEX` will automatically switch to an `INVERTED INDEX`, while existing `BITMAP INDEX` will remain unchanged. This entire switching process is transparent to the user, with no changes to writing or querying. Additionally, users can disable this automatic switch by setting the FE configuration `enable_create_bitmap_index_as_inverted_index` to false. [#35528](https://github.com/apache/doris/pull/35528)
+
+
+## 2 Improvement and optimizations
+
+- Add Trino JDBC Catalog type mapping for JSON and TIME
+
+- FE exit when failed to transfer to (non) master to prevent unknown state and too many logs
+
+- Write audit log while doing drop stats table.
+
+- Ignore min/max column stats if table is partially analyzed to avoid inefficient query plan
+
+- Support minus operation for set like `set1 - set2`
+
+- Improve perfmance of LIKE and REGEXP clause with concat (col, pattern_str), eg. `col1 LIKE concat('%', col2, '%')`
+
+- Add query options for short circuit queries for upgrade compatibility
+

+
+## Behavior changes
+
+- No longer set the default table comment to the table type. Instead, set it to be empty by default, for example, change COMMENT 'OLAP' to COMMENT ' '.  This new behavior is more friendly for BI software that relies on table comments. [#35855](https://github.com/apache/doris/pull/35855)
+
+- Change the type of the `@@autocommit` variable from `BOOLEAN` to `BIGINT` to prevent errors from certain MySQL clients (such as .NET MySQL.Data). [#33282](https://github.com/apache/doris/pull/33282)
+
+
+## Improvements
+
+- Remove the `disable_nested_complex_type` parameter and allow the creation of nested `ARRAY`, `MAP`, and `STRUCT` types by default. [#36255](https://github.com/apache/doris/pull/36255)
+
+- The HMS catalog supports the `SHOW CREATE DATABASE` command. [#28145](https://github.com/apache/doris/pull/28145)
+
+- Add more inverted index metrics to the query profile. [#36545](https://github.com/apache/doris/pull/36545)
+
+- Cross-Cluster Replication (CCR) supports inverted indices. [#31743](https://github.com/apache/doris/pull/31743)

+-->
+
+Thanks to our community users and developers, about 1000 improvements and bug fixes have been made in Doris 2.0.3 version, including optimizer statistics, inverted index, complex datatypes, data lake, replica management.
+
+
+
+## 1 Behavior change
+
+- The output format of the complex data type array/map/struct has been changed to be consistent to the input format and JSON specification. The main changes from the previous version are that DATE/DATETIME and STRING/VARCHAR are enclosed in double quotes and null values inside ARRAY/MAP are displayed as `null` instead of `NULL`.
+  - https://github.com/apache/doris/pull/25946
+- SHOW_VIEW permission is supported. Users with SELECT or LOAD permission will no longer be able to execute the 'SHOW CREATE VIEW' statement and must be granted the SHOW_VIEW permission separately.
+  - https://github.com/apache/doris/pull/25370
+
+
+## 2 New features
+
+### 2.1 Support collecting statistics for optimizer automatically
+
+Collecting statistics helps the optimizer understand the data distribution characteristics and choose a better plan to greatly improve query performance. It is officially supported starting from version 2.0.3 and is enabled all day by default.
+
+### 2.2 Support complex datatypes for more datalake source
+- Support complex datatypes for JAVA UDF, JDBC and Hudi MOR
+  - https://github.com/apache/doris/pull/24810
+  - https://github.com/apache/doris/pull/26236
+- Support complex datatypes for Paimon
+  - https://github.com/apache/doris/pull/25364
+- Suport Paimon version 0.5
+  - https://github.com/apache/doris/pull/24985
+
+
+### 2.3 Add more builtin functions
+- Support the BitmapAgg function in new optimizer
+  - https://github.com/apache/doris/pull/25508
+- Supports SHA series digest functions
+  - https://github.com/apache/doris/pull/24342 
+- Support the BITMAP datatype in the aggregate functions min_by and max_by 
+  - https://github.com/apache/doris/pull/25430 
+- Add milliseconds/microseconds_add/sub/diff functions
+  - https://github.com/apache/doris/pull/24114
+- Add some json functions: json_insert, json_replace, json_set
+  - https://github.com/apache/doris/pull/24384
+
+
+## 3 Improvement and optimizations
+
+### 3.1 Performance optimizations
+
+- When the inverted index MATCH WHERE condition with a high filter rate is combined with the common WHERE condition with a low filter rate, the I/O of the index column is greatly reduced. 
+- Optimize the efficiency of random data access after the where filter.
+- Optimizes the performance of the old get_json_xx function on JSON data types by 2~4x.
+- Supports the configuration to reduce the priority of the data read thread, ensuring the CPU resources for real-time writing.
+- Adds `uuid-numeric` function that returns largeint, which is 20 times faster than `uuid` function that returns string.
+- Optimized the performance of case when by 3x.
+- Cut out unnecessary predicate calculations in storage engine execution.
+- Accelerate count performance by pushing down count operator to storage tier.
+- Optimizes the computation performance of the nullable type in and or expressions.
+- Supports rewriting the limit operator before `join` in more scenarios to improve query performance. 
+- Eliminate useless `order by` operators from inline view to improve query performance.
+- Optimizes the accuracy of cardinality estimates and cost models in some cases. 
+- Optimized jdbc catalog predicate pushdown logic.
+- Optimized the read efficiency of the file cache when it's enable for the first time.
+- Optimizes the hive table sql cache policy and uses the partition update time stored in HMS to improve the cache hit ratio. 
+- Optimize mow compaction efficiency.
+- Optimized thread allocation logic for external table query to reduce memory usage 
+- Optimize memory usage for column reader.
+
+
+
+### 3.2 Distributed replica management improvements
+
+Distributed replica management improvements include skipping partition deletion, colocate group deletion, balance failure due to continuous write, and hot and cold seperation table balance.
+
+
+### 3.3 Security enhancement
+- The audit log plug-in uses a token instead of a plaintext password to enhance security
+  - https://github.com/apache/doris/pull/26278
+- log4j configures security enhancement

+We are excited to announce the release of Apache Doris 3.0! 
+
+**Starting from version 3.X, Apache Doris supports a compute-storage decoupled mode in addition to the compute-storage coupled mode for cluster deployment. With the cloud-native architecture that decouples the computation and storage layers, users can achieve physical isolation between query loads across multiple compute clusters, as well as isolation between read and write loads. Additionally, users can take advantage of low-cost shared storage systems such as object storage or HDFS to significantly reduce storage costs.**
+
+Version 3.0 marks a milestone in the evolution of Apache Doris towards a unified data lake and data warehouse architecture. This version introduces the ability to write data back to data lakes, allowing users to perform data analysis, sharing, processing, and storage operations across multiple data sources within Apache Doris. With capabilities such as asynchronous materialized views, Apache Doris can serve as a unified data processing engine for enterprises, helping users better manage data across lakes, warehouses, and databases. Also, Apache Doris 3.0 introduces the Trino Connector. It allows users to quickly connect or adapt to more data sources, and leverage the high-performance compute engine of Doris to deliver faster query results than Trino.
+
+Version 3.0 also enhances support for ETL batch processing scenarios, adding explicit transaction support for operations like `insert into select`, `delete` and `update`. The observability of query execution has also been improved.
+
+In terms of performance, we have improved the framework capabilities, infrastructure, and rules of the query optimizer in version 3.0. This provides optimized performance, which has been proven by blind testing in more complex and diverse business scenarios.
+
+The adaptive Runtime Filter computation method now accurately estimates filters based on data size during execution, delivering better performance under large data volumes and high loads. Additionally, asynchronous materialized view has been more stable and user-friendly in query acceleration and data modeling. 
+
+**During the development of version 3.0, over 200 contributors submitted nearly 5,000 optimizations** and fixes to Apache Doris. Contributors from companies such as VeloDB, Baidu, Meituan, ByteDance, Tencent, Alibaba, Kwai, Huawei, and Tianyi Cloud actively collaborated with the community, contributing test cases from real-world use cases to help us improve Apache Doris. We extend our heartfelt thanks to all the contributors involved in the development, testing, and feedback process for this release.

+
+## 1. Compute-storage decoupled mode
+
+Since V3.0, Apache Doris supports the compute-storage decoupled mode. Users can choose between it and the compute-storage coupled mode during cluster deployment.
+
+In the compute-storage decoupled mode, the BE nodes no longer store the data, but instead, a shared storage layer (HDFS and object storage) is introduced as the shared data storage layer. The computing and storage resources can be scaled independently, bringing multiple benefits to users:
+
+- **Workload isolation**: Multiple compute clusters can share the same data, allowing users to isolate different business workloads or offline loads using separate compute clusters.
+
+- **Reduced storage costs**: The full dataset is stored in the more cost-effective and highly reliable shared storage, with only hot data cached locally. Compared to the compute-storage coupled mode with three data replicas, the storage cost can be reduced by up to 90%.
+
+- **Elastic computing resources**: Since no data is stored on the BE nodes, the computing resources can be scaled flexibly based on the load requirements. Users can scale in or out an individual compute cluster or increase/decrease the number of compute clusters. This also leads to cost savings.
+
+- **Improved system robustness**: By storing the data in shared storage, Doris no longer needs to handle the complex logic of multi-replica consistency, thus simplifying distributed storage complexity and improving the overall system robustness.
+
+- **Flexible data sharing and cloning**: The flexibility of the compute-storage decoupled mode extends beyond a single Doris cluster. Tables from one Doris cluster can be easily cloned to another Doris cluster, with just metadata replication.
+
+### 1-1. From coupled to decoupled
+
+In the compute-storage coupled mode, the Apache Doris architecture consists of two main process types: Frontend (FE) and Backend (BE). The FE is primarily responsible for user request access, query parsing and planning, metadata management, and node management. The BE is responsible for data storage and query plan execution. 
+
+The BE nodes employ an MPP (Massively Parallel Processing) distributed computing architecture, leveraging a multi-replica consistency protocol to ensure high service availability and high data reliability.
+
+![From coupled to decoupled](/images/storage-compute-decoupled.PNG)
+
+
+The maturation of emerging cloud computing infrastructure, including public clouds, private clouds, and Kubernetes-based container platforms, has driven the need for cloud-native capabilities. Increasingly, users are seeking deeper integration between Apache Doris and cloud computing infrastructure to provide more elasticity.
+
+**To address this need, the VeloDB team has designed and implemented a cloud-native version of Apache Doris that decouples compute and storage, known as VeloDB Cloud.  After extensive production testing and refinement across hundreds of enterprises over a long time, this cloud-native solution has now been contributed to the Apache Doris community, manifesting as the Apache Doris 3.0 in the compute-storage decoupled mode.**
+
+In the compute-storage decoupled mode, the Apache Doris architecture consists of three layers:
+
+- **Meta data layer**: A new Meta Service module has been introduced to provide meta data services, such as processing database and table information, schemas, rowset meta, and transactions. The Meta Service is stateless and horizontally scalable. In V3.0, all of the BE's meta data and parts of the FE's meta data have been migrated to the Meta Service. We will finish the migration of the remains in future versions.
+- **Computation layer**: The stateless BE nodes execute query plans and cache a portion of the data and tablet meta data locally to improve query performance. Multiple stateless BE nodes can be organized into a computing resource pool (i.e., compute cluster), and multiple compute clusters can share the same data and metadata service. The compute clusters can be elastically scaled by adding or removing nodes as needed.
+- **Shared storage layer**: Data is persisted to the shared storage layer, which currently supports HDFS as well as various cloud-based object storage systems that are compatible with the S3 protocol, such as S3, OSS, GCS, Azure Blob, COS, BOS, and MinIO.
+
+![From coupled to decoupled-2](/images/storage-compute-decoupled-2.JPEG)
+
+### 1-2 Design highlight
+
+The design of the compute-storage decoupled mode of Apache Doris highlights the transformation of the FE's in-memory metadata model into a shared metadata service. This approach offers a globally consistent state view, allowing any node to directly submit writes without needing to go through the FE for publishing. During write operations, data is stored in shared storage, while metadata is managed by the metadata service. **This effectively controls the number of small files in shared storage. Meanwhile, the real-time write performance for individual tables is nearly on par with that in the compute-storage coupled mode. The system's overall write capacity is no longer limited by the processing power of a single FE node.**
+
+![Design highlight](/images/design-hightlight.PNG)
+
+Based on the globally consistent state view, for data garbage collection, we have adopted a design approach for data deletion that is easier to prove correct and more efficient.
+
+Specifically, data in the shared storage is incorporated into the globally consistent view offered by the shared meta data service. Whenever data is generated, we bind it to a separate, independent transaction. Similarly, for a meta data deletion operation, we also bind it to a separate, independent transaction. The purpose of this approach is to ensure that deletion and write operations cannot succeed together. The view records which data needs to be deleted, and the asynchronous deletion process can simply perform a forward deletion of the data based on the transaction records, without the need for reverse garbage collection.
+
+As the tablet-related meta data in the FE is gradually migrated to the shared meta data service, the scalability of the Doris cluster will no longer be constrained by the memory capacity of a single FE node. Building upon the shared meta data service and the forward data deletion technique, we can conveniently expand functionality such as data sharing and lightweight cloning.
+
+### 1-3 Comparison with alternative solutions
+
+Another design of decoupling compute and storage in the industry is to store the data and BE node meta data in a shared object storage or HDFS. However, this approach brings the following problems:
+
+- **Inability to support real-time writes**: During data writes, the data is mapped to tablets based on the partitioning and bucketing rules, generating segment files and rowset meta data. During the write process, a two-phase commit (Publish) is performed through the FE. When a BE node receives the Publish request, it then sets the rowset as visible. The Publish operation must not fail. If the rowset meta data is stored in the shared storage, the total small file data during the real-time write process would triple the size of the actual data files - one replica of data files, one for rowset meta data, and another for rowset meta data changes during Publish. The Publish operation is driven by a single FE node, so the write capacity of a single table or even the entire system is limited by the FE node's capabilities.
+  
+  ![Comparison with alternative solutions](/images/comparison-with-alternative-solutions.png)
+
+  We compared the real-time data write performance of Apache Doris 3.0 with the above-described solution. We simulated 500 concurrent tasks writing 10,000 data files with 500 rows each, and 50 concurrent tasks writing 250 data files with 20,000 rows each, using the same computational resources. 
+
+  **The results showed that at 50 concurrent tasks, the micro-batch write performances of Apache Doris in both compute-storage coupled and decoupled modes were almost identical, while the industry solution lagged behind Apache Doris by a factor of 100.** 
+
+  At 500 concurrent tasks, the performance of Apache Doris in the compute-storage decoupled mode showed slight degradation, but it still maintained an 11X advantage over the industry solution. To ensure a fair test, Apache Doris did not enable the Group Commit feature (which the industry solution lacks). Enabling Group Commit would further enhance real-time write performance.
+
+  ![Comparison with alternative solutions](/images/real-time-write-performance..png)
+
+  Additionally, the industry solution also faces stability and cost issues in terms of real-time data ingestion:
+
+  - Stability concerns: A large number of small files can put pressure on the shared storage, especially HDFS, and introduce stability risks.
+
+  - High object storage request costs: Some public cloud object storage services charge 10 times more for Put and Delete operations compared to Get operations. A large number of small files can lead to a significant increase in object storage request costs, which can even exceed the storage costs.
+
+- **Limited scalability**: Use cases of the compute-storage decoupled model often handles larger data storage sizes, since the FE (Frontend) meta data is entirely in-memory, when the number of tablets reaches a certain high level (e.g. tens of millions), the FE's memory pressure can become a bottleneck that limits the overall write throughput of the system.
+
+- **Potential data deletion logic issues**: In the compute-storage decoupled architecture, data is stored with one single replica. Therefore, the data deletion logic is critical for the system's reliability. The conventional approach of cross-system data deletion by comparing the differences can be challenging. During the write process, there is no way to completely avoid deletion and write from succeeding together, which can lead to data loss. Additionally, when the storage system experiences anomalies, the input used for difference calculation may be incorrect, which potentially leads to unintended data deletion.
+
+- **Data sharing and lightweight cloning**: The flexibility of the decoupled storage-compute architecture can enable future data sharing and lightweight data cloning, reducing the burden of enterprise data management. However, if each cluster has a separate FE, after cloning data across clusters, it becomes difficult to accurately determine which data is no longer referenced and can be safely deleted, as calculating cross-cluster references can easily lead to unintended data deletion.
+
+By evolving the FE's full in-memory meta data model into a shared meta data service, Apache Doris 3.0 avoids all the aforementioned issues.
+
+### 1-4 Query performance comparison
+
+In the compute-storage decoupled mode, data needs to be read from the remote shared storage system, the main bottleneck has become the network bandwidth instead of the disk I/O in the compute-storage coupled mode. 
+
+To accelerate data access, Apache Doris has implemented a high-speed caching mechanism based on local disks, and provides two cache management policies: LRU (Least Recently Used) and TTL (Time-To-Live). The newly imported data is asynchronously written to the cache to accelerate the first-time access to the latest data. If the data required by a query is not in the cache, the system will read the data from the remote storage into memory and synchronously write it to the cache for subsequent queries.
+
+In use cases involving multiple compute clusters, Apache Doris provides a cache preheating function. When a new compute cluster is established, users can choose to preheat specific data (such as tables or partitions) to further improve query efficiency.
+
+In this context, we have conducted performance tests with different caching strategies in both the compute-storage coupled and decoupled modes, using the TPC-DS 1TB test dataset. The results are concluded as follows:
+
+- When the cache is fully hit (i.e., all the data required for the query is loaded into the cache), **the query performance of the compute-storage decoupled mode is on par with that of the compute-storage coupled mode**.
+
+- When the cache is partially hit (i.e., the cache is cleared before the test, and data is gradually loaded into the cache during the test, with performance continuously improving), the query performance of the compute-storage decoupled mode is about 10% lower than that of the compute-storage coupled mode. This test scenario is the most similar to the real-life use cases.
+
+- When the cache is completely missed (i.e., the cache is cleared before every SQL execution, simulating an extreme case), the performance loss is around 35%. **Even so, Apache Doris in the compute-storage decoupled mode delivers much higher performance than its alternative solutions.**
+
+![Query performance comparison](/images/query-performance-comparison.png)
+
+### 1-5 Write speed comparison
+
+In terms of write performance, we have simulated two test cases under the same computing resources: batch import and high-concurrency real-time import. The comparison of write performance between the compute-storage coupled mode and the compute-storage decoupled mode is as follows:
+
+- **Batch import**: When importing the 1TB TPC-H and 1TB TPC-DS test datasets, **the write performance of the compute-storage decoupled mode is 20.05% and 27.98% higher than the compute-storage coupled mode**, respectively, under the single-replica configuration. During batch import, the segment file size is generally in the range of tens to hundreds of MB. In the compute-storage decoupled mode, the segment files are split into smaller files and concurrently uploaded to the object storage, which can result in higher throughput compared to writing to local disks. In real-life deployments, the compute-storage coupled mode typically uses three replicas, which means the write speed advantage of the compute-storage decoupled mode will be even more pronounced.
+
+- **High-concurrency real-time import**: as described in the "Comparison with alternative solutions" section.
+
+![Write speed comparison](/images/write-speed-comparison.png)
+
+### 1-6 Tips for production environment
+
+- **Performance**: For real-time data analysis, users can achieve query performance comparable to the compute-storage coupled mode by specifying a TTL (Time-To-Live) for the cache and writing newly ingested data into the cache. To prevent query jitter, users can cache the data generated by background tasks such as compaction and schema changes based on how frequently used the data is.
+
+- **Workload isolation**: Users can achieve physical resource isolation for different business using multiple compute clusters. For workload isolation within a single compute cluster, users can utilize the Workload Group mechanism to limit and isolate resources for different queries.
+
+### 1-7 Notes
+
+- Apache Doris 3.0 does not support the co-existence of the compute-storage coupled mode and the compute-storage decoupled mode. Users need to specify one of them during cluster deployment.
+
+- If users need the compute-storage coupled mode, following the [documentation](https://doris.apache.org/docs/3.0/install/source-install/compilation-with-docker/) for its deployment and upgrade. We recommend using Doris Manager for quick deployment and cluster upgrades. However, the compute-storage decoupled mode does not yet support Doris Manager deployment and upgrade. We will continue iteration for better support in future versions.
+
+- Currently Apache Doris does not support in-place upgrade from V2.1 to the compute-storage decoupled mode of V3.0. For such purpose, users need to perform data migration using tools like X2Doris after deploying the compute-storage decoupled clusters. In the future, we will support migration without service interruption through the CCR (Change Data Capture) capability.

+
+## 2. Data lakehouse
+
+Apache Doris is positioned as a real-time data warehouse, but it is much more than that. In previous versions, we have consistently pushed beyond the boundaries of traditional data warehouse capabilities, advancing towards a unified data lakehouse. Version 3.0 marks a milestone in this journey, with its capabilities in the lakehouse architecture becoming fully mature. We believe that a unified lakehouse is identified by **boundaryless data** and **lakehouse fusion**:
+
+**Boundaryless data: Apache Doris serves as a unified query processing engine, breaking down data barriers across different systems. It provides a consistent and ultra-fast analysis experience across all data sources, including data warehouses, data lakes, data streams, and local data files.**
+
+- **Lakehouse query acceleration**: Without the need to migrate data to Apache Doris, users can leverage Doris’ efficient query engine to directly query data stored in data lakes such as Iceberg, Hudi, Paimon, and offline data warehouses like Hive, thereby accelerating query analysis.
+
+- **Federated analysis**: By extending its catalog and storage plugins, Apache Doris enhances its federated analysis capabilities, allowing users to perform unified analysis across multiple heterogeneous data sources without physically centralizing the data in a single storage system. This enables external table queries and federated joins between internal and external tables, breaking down data silos and providing globally consistent data insights.
+
+- **Data lake construction**: Apache Doris introduces write-back functionality for Hive and Iceberg, allowing users to directly create Hive and Iceberg tables through Doris and write data into them. This allows users to write internal table data back to the offline lakehouse or process offline lakehouse data using Doris and save the results back into the lakehouse, simplifying and streamlining the data lake construction process.
+
+**Lakehouse fusion: As data lake architectures become increasingly complex, the costs of technology selection and maintenance rise for users. Achieving consistent fine-grained access control across multiple systems also becomes challenging, and real-time performance suffers. To address this, Apache Doris integrates core features of the data lake, transforming itself into a lightweight, efficient, native real-time lakehouse.**
+
+- **Real-time data updates**: Starting with version 1.2, Apache Doris enhanced the primary key model by introducing Merge-on-Write, supporting real-time updates. This feature allows high-frequency, real-time data updates based on primary key changes from upstream data sources.
+
+- **Data science and** **AI** **computation support**: From version 2.1, Apache Doris, using the efficient Arrow Flight protocol, increased the openness of its storage system and its support for various compute loads, enabling data science and AI computations.
+
+- **Enhancements for semi-structured and unstructured Data**: Apache Doris has introduced support for data types like Array, Map, Struct, JSON, and Variant, with plans to support vector indexing in the future.
+
+- **Improved resource efficiency by decoupling storage and compute**: With version 3.0, Apache Doris supports a decoupled storage and compute mode, further improving resource efficiency and scalability.
+
+### 2-1 Faster queries in the data lakehouse
+
+TPC-H and TPC-DS benchmarking proves that Apache Doris achieves average query performance that is 3 to 5 times faster than Trino/Presto.
+
+In V3.0, we have focused on optimizing query performance for production environments, including:
+
+- **More granular task splitting strategy**: By adjusting the consistent hashing algorithm and introducing a task sharding weighting mechanism, we ensure balanced query loads across all nodes.
+
+- **Scheduling optimizations for use cases with numerous partitions and files**: For cases with a large number of files (over 1 million), we have largely reduced query latency (from 100 seconds to 10 seconds) and alleviated memory pressure on the Frontend (FE) by asynchronously and batch-fetching file shards.
+
+We will continue to specifically enhance query acceleration performance in real-world business scenarios, improve the actual user experience, and build an industry-leading lakehouse query acceleration engine.
+
+### 2-2 Federated analysis: more data connectors
+
+Previous versions of Apache Doris support connectors for over 10 mainstream data lakehouses, warehouses, and relational databases. In V3.0, we have introduced the Trino Connector compatibility framework, which expands the range of data sources that Apache Doris can connect to. With this framework, users can easily adapt their existing setups to access corresponding data sources using Doris and leverage its high-speed computing engine for data analysis.
+
+Currently, Doris has completed adaptations for Delta Lake, Kudu, BigQuery, Kafka, TPCH, and TPCDS. We also encourage contributions from developers to prolong this list.

+
+
+### 2-3 Data lake building
+
+In V3.0, we have introduced data writeback functionality for Hive and Iceberg. This allows users to create Hive and Iceberg tables directly through Doris and write data into these tables, and enables users to perform data analysis, sharing, processing, and storage operations across multiple data sources within Doris.
+
+In future iterations, Apache Doris will further enhance support for data lake table formats and improve the openness of storage APIs.
+
+:::info Note
+See doc: https://doris.apache.org/docs/3.0/lakehouse/datalake-building/hive-build/
+:::
+
+## 3. Upgraded semi-structured data analysis capabilities
+
+In versions 2.0 and 2.1, Apache Doris introduced some well-embraced features such as inverted index, NGram Bloom Filter, and Variant data type to support high-performance full-text search and multi-dimensional analysis. With them, the storage and processing of complex semi-structured data have been more flexible and efficient.
+
+In V3.0, we have further enhanced the capabilities in this scenario.
+
+After extensive testing in production environments, the Variant data type has gained sufficient stability and become the preferred choice for JSON data storage and analysis. In V3.0, we have made multiple optimizations to it:
+
+- Support for indexing of the Variant data type to accelerate queries, including inverted index, Bloom Filter index, and the built-in ZoneMap index.
+
+- Support for flexible partial column updates for Unique Key tables containing the Variant data type.
+
+- Support for the use of the Variant data type in the compute-storage decoupled mode, with optimizations of its metadata storage.
+
+- Support for exporting the Variant data type to formats such as Parquet and CSV.
+
+The inverted index, introduced since V2.0, has reached a high level of maturity after more than a year of refinement and is now running in production environments of hundreds of enterprises. In V3.0, we have made multiple optimizations to the inverted index:
+
+- After performance optimizations, including lock concurrency, Apache Doris outperforms Elasticsearch in key metrics such as query latency and concurrency in real-time reporting analysis.
+
+- Optimized index file in the compute-storage decoupled mode to reduce remote storage calls and decrease index query latency.
+
+- Support for the Array data type to accelerate the `array_contains` queries.
+
+- Enhanced the `match_phrase_*` functionality, including support for slop and phrase prefix matching `match_phrase_prefix`.
+
+## 4. Enhanced ETL capabilities
+
+### 4-1. Transaction improvements
+
+Data processing in data warehouses often involves multiple data changes that need to be handled as a single transaction. V3.0 provides explicit transaction support for `insert into select`, `delete`, and `update` operations. Example cases include:
+
+- **Transactional requirements**: For example, when updating data within a time range, the typical approach is to first delete the data in that time range, and then insert the new data. Considering that the data might already be in service, there is a need to ensure that queries visit either the old data or the new data. Thus, it can be achieved by executing the `delete` and `insert into select` operations in a transaction.
+
+  ```Java
+  BEGIN;
+  DELETE FROM table WHERE date >= "2024-07-01" AND date <= "2024-07-31";
+  INSERT INTO table SELECT * FROM stage_table;
+  COMMIT;
+  ```
+
+- **Simplified the processing of failed tasks**: For example, when two `insert into select` operations are executed within a single transaction, if any of the operations fail, it can be retried directly.
+  
+  ```Java
+  BEGIN WITH LABEL label_etl_1;
+  INTO table1 SELECT * FROM stage_table1;
+  INSERT INTO table SELECT * FROM stage_table;
+  COMMIT;
+  ```
+
+:::info Note
+See doc: https://doris.apache.org/docs/3.0/data-operate/transaction/
+Currently, explicit transaction synchronization is not supported in Cross-Cluster Replication (CCR).
+:::
+
+### 4-2. Improved observability
+
+- **Real-time profile retrieval**: In previous versions, due to issues with the execution plan or the data, some complex queries might have high computational requirements, so developers can only access the query profile for performance analysis after the completion of the query. This makes it hard to promptly identify issues in query execution to guarantee stability of the production environment. Now, with the ability to retrieve real-time profiles, V3.0 allows users to monitor query execution as the query is running. It also allows them to better monitor the progress of each ETL job.
+
+- **`backend_active_tasks` system table**: The `backend_active_tasks` system table provides real-time resource consumption information for each query on each BE node. Users can analyze this system table using SQL to obtain the resource usage of each query, which helps identify large queries or abnormal workloads.
+
+## 5. Asynchronous materialized view
+
+In V3.0, asynchronous materialized view is faster and more stable. It is also more user-friendly for query acceleration and data modeling scenarios. We have restructured the logic for transparent rewrite and expanded its capabilities, making it 2X faster.
+
+### 5-1 Refresh
+
+- Support for incremental update of materialized views by partitions and partition roll-ups on materialized views to allow refreshes at different granularities.
+
+- Support for nested materialized views, which is useful in data modeling scenarios.
+
+- Support for index creation and sort key specification in asynchronous materialized views, which will improve query performance after the materialized view is hit.
+
+- Higher usability of materialized view DDL with support for atomically replacing materialized views, allowing modifications to the materialized view definition SQL while keeping the materialized view available. 
+
+- Support for non-deterministic functions in materialized views to better serve daily materialized view creation.
+
+- Support for trigger-based materialized view refresh, which ensures data consistency in data modeling with nested materialized views.
+
+- Support for a broader range of SQL patterns for building partitioned materialized views, making the incremental update capability available to more use cases.
+
+### 5-2 Refresh stability
+
+- V3.0 supports specifying a Workload Group for building materialized views. This is to limit the resources used by the materialized view build process and ensure that sufficient resources remain available for ongoing queries.
+
+### 5-3 Transparent rewrite
+
+- Support for transparent rewrite of more Join types, including derived Joins. Even when there is a mismatch of Join types between the query and materialized view, transparent rewrite can still be performed by compensating with additional predicates, as long as the materialized view can provide all the data needed for the query.
+
+- Support for more aggregate functions for roll-up as well as rewrite of multi-dimensional aggregations like GROUPING SETS, ROLLUP, and CUBE; support rewriting queries with aggregations when the materialized view does not contain aggregations, simplifying Join operations and expression computation.
+
+- Support for transparent rewrite of nested materialized views, enabling higher performance for complex queries.
+
+- For partially invalid partitioned materialized views, V3.0 supports `Union All` the base tables for data completion, expanding the applicability of partitioned materialized views.
+
+### 5-4 Transparent rewrite performance
+
+- Continuous optimization has been done to improve the transparent rewrite performance, achieving 2X the speed compared to version 2.1.0.

+
+## 6. Performance improvement
+
+### 6-1 Smarter optimizer
+
+In V3.0, the query optimizer has been enhanced in terms of framework capabilities, distributed plan support, optimizer infrastructure, and rule expansion. It provides better optimization capabilities for more complex and diverse business scenarios, with higher blind test performance for complex SQL:
+
+- **Improved plan enumeration capability**: The key structure Memo for plan enumeration has been restructured and normalized. This improves the efficiency of the Cascades framework in plan enumeration and the possibility of producing better plans. Additionally, it fixes incomplete column pruning during the Join Reorder process in older versions, which led to unnecessary overhead of the Join operator, thus improving the execution performance in the relevant scenarios.
+
+- **Improved distributed plan support**: The distributed query plan has been enhanced to allow aggregation, join, and window function operations to more intelligently identify the data characteristics of intermediate computation results, avoiding ineffective data redistribution operations. Meanwhile, we have optimized the execution under the multi-replica continuous execution mode, making it more data cache-friendly.
+
+- **Improved optimizer infrastructure**: V3 has fixed several issues in cost model and statistics information estimation. The fixes to the cost model are more adaptable to the evolution of the execution engine, making the execution plan more stable compared to previous versions.
+
+- **Enhanced Runtime Filter plan support**: On the basis of Join Runtime Filter, V3.0 has expanded the capability of the TopN Runtime Filter to achieve better performance in use cases that involve a TopN operator.
+
+- **Enriched optimization rule library**: Based on user feedback and internal testing results, we have introduced optimization rules such as Intersect Reorder to enrich the rule set of the optimizer.
+
+### 6-2 Self-adaptive Runtime Filter
+
+In previous versions, the generation of Runtime Filter relies on manual setting by users based on statistical information. However, inaccurate settings in certain cases could lead to performance instability.
+
+In V3.0, Doris implements a self-adaptive Runtime Filter calculation approach. It can estimate the Runtime Filter at runtime based on the data size with high accuracy, enabling better performance in use cases with large data volumes and high workloads. 
+
+### 6-3 Function performance optimization
+
+- V3.0 has improved the vectorized implementation of dozens of functions, enabling a performance improvement of over 50% for some commonly used functions.
+- V3.0 has also made extensive optimizations to the aggregation of nullable data types, enabling a 30% performance improvement.
+
+### 6-4 Blind test performance improvement
+
+Our blind tests on V3.0 and V2.1 show that the new version is 7.3% and 6.2% faster in TPC-DS and TPC-H benchmark tests, respectively.

+
+## 7. New features
+
+### 7-1 Java UDTF
+
+Version 3.0 has added support for Java UDTFs. The key operations are as follows:
+
+- Implementing a UDTF: Similar to a UDF, a UDTF requires the user to implement an `evaluate` method. Note that the return value of a UDTF function must be of the `Array` data type.
+
+  ```sql
+  public class UDTFStringTest {
+      public ArrayList<String> evaluate(String value, String separator) {
+          if (value == null || separator == null) {
+              return null;
+          } else {
+              return new ArrayList<>(Arrays.asList(value.split(separator)));
+          }
+      }
+  }
+  ```
+
+- Creating a UDTF: By default, two corresponding functions will be created - `java-utdf`and `java-utdf_outer`. The `_outer` suffix adds a single row of `NULL` data when the table function generates 0 rows of output.
+
+  ```sql
+  CREATE TABLES FUNCTION java-utdf(string, string) RETURNS array<string> PROPERTIES (
+      "file"="file:///pathTo/java-udaf.jar",
+      "symbol"="org.apache.doris.udf.demo.UDTFStringTest",
+      "always_nullable"="true",
+      "type"="JAVA_UDF"
+  );
+  ```
+
+:::info
+
+See doc: https://doris.apache.org/docs/3.0/query/udf/java-user-defined-function/#udtf-1
+
+:::
+
+### 7-2 Generated column
+
+A generated column is a special column whose value is calculated from the values of other columns rather than directly inserted or updated by the user. It supports pre-computing the results of expressions and storing them in the database, which is suitable for scenarios that require frequent queries or complex calculations.
+
+Results can be automatically calculated based on predefined expressions when data is imported or updated, and then stored persistently. In this way, during subsequent queries, the system can directly access these calculated results without performing complex calculations, thereby improving query performance.
+
+Generated columns are supported since V3.0. When creating a table, you can specify a column as generated column. A generated column automatically calculates values based on the defined expression when data is written. Generated columns allow for more complex expressions to be defined, but the value cannot be explicitly written or set.

+
+## 8. Functional improvements
+
+### 8-1. Materialized view
+
+We have refactored the selection logic for materialized views and migrated it from the rule-based optimizer (RBO) to the cost-based optimizer (CBO). This aligns the selection logic with that of asynchronous materialized views. This functionality is enabled by default. If any issues are encountered, you can revert to the RBO mode using `set global enable_sync_mv_cost_based_rewrite = false`.
+
+### 8-2. Routine Load
+
+In previous versions, the Routine Load functionality faced some usability challenges, such as uneven task scheduling across BE nodes, untimely task scheduling, complex configuration requirements (the need to change multiple FE and BE settings for optimization), insufficient overall stability (where restarts or upgrades could frequently pause Routine Load jobs, requiring manual user intervention to resume).
+
+To address these issues, we have made extensive optimizations to the Routine Load feature:
+
+- **Resource scheduling**: We have improved the scheduling balance to make sure that tasks are more evenly distributed across BE nodes. Jobs that encounter unrepairable errors will be promptly paused to avoid wasting resources on futile scheduling attempts. Additionally, we have improved the timeliness of the scheduling process, which has enhanced the import performance of Routine Load.
+
+- **Parameter configuration**: Users in most environments no longer need to modify FE and BE configurations for optimization. An automatic adjustment mechanism with timeout parameter has been introduced to prevent tasks from constantly retrying when cluster pressure increases.
+
+- **Stability**: We have enhanced the robustness of Doris in various exceptional scenarios, such as FE failovers, BE rolling upgrades, and Kafka cluster anomalies, ensuring continuous stable operation. We have also optimized the Auto Resume mechanism, allowing Routine Load to automatically resume operation after faults are repaired, reducing the need for manual user intervention.
+
+## 9. Behavior changed
+
+- `cpu_resource_limit` will no longer be supported, and all types of resource isolation will be implemented through Workload Groups.
+
+- Please use JDK 17 for Apache Doris 3.0 and later versions. The recommended version being `jdk-17.0.10_linux-x64_bin.tar.gz`.
+
+## Try Apache Doris 3.0 now!
+
+Before the official release of version 3.0, the compute-storage decoupled mode of Apache Doris has undergone nearly two years of extensive testing and optimization in the production environments of hundreds of enterprises. Contributors from many tech giants have collaborated with the community to provide a significant number of test cases based on their real-world business needs. This has rigorously validated the usability and stability of version 3.0.
+
+We highly recommend users with compute-storage decoupling needs to download version 3.0 and experience it firsthand.
+
+Going forward, we will accelerate our release iteration cycle to deliver a more stable version experience for all users. Feel free to join us in the [Apache Doris community](https://join.slack.com/t/apachedoriscommunity/shared_invite/zt-2gmq5o30h-455W226d79zP3L96ZhXIoQ) and engage directly with the core developers.

+
+## Behavior Changes
+
+### Query Optimizer
+
+- Added the variable `use_max_length_of_varchar_in_ctas` to control the length behavior of VARCHAR type when executing `CREATE TABLE AS SELECT` (CTAS) operations.  [#37069](https://github.com/apache/doris/pull/37069)
+  
+  - This variable is set to true by default. 
+  
+  - When set to true, if the VARCHAR type column originates from a table, the derived length is used; otherwise, the maximum length is used. 
+  
+  - When set to false, the VARCHAR type will always use the derived length.
+
+- All data types will now be displayed in lowercase to maintain compatibility with MySQL format. [#38012](https://github.com/apache/doris/pull/38012)
+
+- Multiple query statements in the same query request must now be separated by semicolons. [#38670](https://github.com/apache/doris/pull/38670)
+
+### Query Execution
+
+- The default number of parallel tasks after shuffle operations in the cluster is set to 100, which will improve query stability and concurrent processing capability in large clusters. [#38196](https://github.com/apache/doris/pull/38196)
+
+### Storage
+
+- The default value of `trash_file_expire_time_sec` has been changed from 86400 seconds to 0 seconds, which means that if files are deleted by mistake and the FE trash is cleared, the data cannot be recovered.
+
+- The table attribute `enable_mow_delete_on_delete_predicate` (introduced in version 3.0.0) has been renamed to `enable_mow_light_delete`.
+
+- Explicit transactions are now prohibited from performing delete operations on tables with written data.
+
+- Heavy schema change operations are prohibited on tables with auto-increment fields.
+
+
+
+## New Features
+
+### Job Scheduling
+
+- Optimized the execution logic of internal scheduling jobs, decoupling the strong association between start time and immediate execution parameters. Now, tasks can be created with a specified start time or selected for immediate execution, without conflict, enhancing scheduling flexibility. [#36805](https://github.com/apache/doris/pull/36805)
+
+### Compute-Storage Decoupled
+
+- Supports dynamic modification of the upper limit for file cache usage. [#37484](https://github.com/apache/doris/pull/37484)
+
+- Recycler now supports object storage rate limiting and server-side rate limiting retry functionality. [#37663](https://github.com/apache/doris/pull/37663) [#37680](https://github.com/apache/doris/pull/37680)
+
+### Lakehouse
+
+- Added the session variable `serde_dialect` to set the output format for complex types. [#37039](https://github.com/apache/doris/pull/37039)
+
+- SQL interception now supports external tables.
+
+  - For more information, refer to the documentation on  [SQL Interception](https://doris.apache.org/docs/admin-manual/query-admin/sql-interception).
+
+- Insert overwrite now supports Iceberg tables. [#37191](https://github.com/apache/doris/pull/37191)
+
+### Asynchronous Materialized Views
+
+- Supports partition roll-up and build at the hourly level. [#37678](https://github.com/apache/doris/pull/37678)
+
+- Supports atomic replacement of asynchronous materialized view definition statements. [#36749](https://github.com/apache/doris/pull/36749)
+
+- Transparent rewriting now supports Insert statements. [#38115](https://github.com/apache/doris/pull/38115)
+
+- Transparent rewriting now supports the VARIANT type. [#37929](https://github.com/apache/doris/pull/37929)
+
+### Query Execution
+
+- The group concat function now supports DISTINCT and ORDER BY options. [#38744](https://github.com/apache/doris/pull/38744)
+
+### Semi-Structured Data Management

+
+- Added the `explode_json_object` function, which can unfold objects in JSON data into multiple rows. [#36887](https://github.com/apache/doris/pull/36887)
+
+- Inverted indexes now support memtable advancement, requiring index construction only once during multi-replica writes, reducing CPU consumption and improving performance. [#35891](https://github.com/apache/doris/pull/35891)
+
+- Added `MATCH_PHRASE` support for positive slop, e.g., `msg MATCH_PHRASE 'a b 2+'` can match instances containing words a and b with a slop of no more than two, and a preceding b; regular slop without the final `+` does not guarantee this order. [#36356](https://github.com/apache/doris/pull/36356)
+
+### Other
+
+- Added the FE parameter `skip_audit_user_list`, where user operations specified in this configuration will not be recorded in the audit log. [#38310](https://github.com/apache/doris/pull/38310)
+
+  - For more information, refer to the documentation on [Audit Plugin](https://doris.apache.org/docs/admin-manual/audit-plugin/).

+
+In version 1.1, we realized the full vectorization of the computing layer and storage layer, and officially enabled the vectorized execution engine as a stable function. All queries are executed by the vectorized execution engine by default, and the performance is 3-5 times higher than the previous version. It increases the ability to access the external tables of Apache Iceberg and supports federated query of data in Doris and Iceberg, and expands the analysis capabilities of Apache Doris on the data lake; on the basis of the original LZ4, the ZSTD compression algorithm is added , further improves the data compression rate; fixed many performance and stability problems in previous versions, greatly improving system stability. Downloading and using is recommended.
+
+## Upgrade Notes
+
+### The vectorized execution engine is enabled by default
+
+In version 1.0, we introduced the vectorized execution engine as an experimental feature and Users need to manually enable it when executing queries by configuring the session variables through `set batch_size = 4096` and `set enable_vectorized_engine = true` .
+
+In version 1.1, we officially fully enabled the vectorized execution engine as a stable function. The session variable `enable_vectorized_engine` is set to true by default. All queries are executed by default through the vectorized execution engine.
+
+### BE Binary File Renaming
+
+BE binary file has been renamed from palo_be to doris_be . Please pay attention to modifying the relevant scripts if you used to rely on process names for cluster management and other operations.
+
+### Segment storage format upgrade
+
+The storage format of earlier versions of Apache Doris was Segment V1. In version 0.12, we had implemented Segment V2 as a new storage format, which introduced Bitmap indexes, memory tables, page cache, dictionary compression, delayed materialization and many other features. Starting from version 0.13, the default storage format for newly created tables is Segment V2, while maintaining compatibility with the Segment V1 format.
+
+In order to ensure the maintainability of the code structure and reduce the additional learning and development costs caused by redundant historical codes, we have decided to no longer support the Segment v1 storage format from the next version. It is expected that this part of the code will be deleted in the Apache Doris 1.2 version.
+
+### Normal Upgrade
+
+For normal upgrade operations, you can perform rolling upgrades according to the cluster upgrade documentation on the official website.
+
+[https://doris.apache.org//docs/admin-manual/cluster-management/upgrade](https://doris.apache.org//docs/admin-manual/cluster-management/upgrade)
+
+## Features
+
+### Support random distribution of data [experimental]
+
+In some scenarios (such as log data analysis), users may not be able to find a suitable bucket key to avoid data skew, so the system needs to provide additional distribution methods to solve the problem.
+
+Therefore, when creating a table you can set `DISTRIBUTED BY random BUCKETS number`to use random distribution, the data will be randomly written to a single tablet when importing to reduce the data fanout during the loading process. And reduce resource overhead and improve system stability.
+
+### Support for creating Iceberg external tables[experimental]
+
+Iceberg external tables provide Apache Doris with direct access to data stored in Iceberg. Through Iceberg external tables, federated queries on data stored in local storage and Iceberg can be implemented, which saves tedious data loading work, simplifies the system architecture for data analysis, and performs more complex analysis operations.
+
+In version 1.1, Apache Doris supports creating Iceberg external tables and querying data, and supports automatic synchronization of all table schemas in the Iceberg database through the REFRESH command.
+
+### Added ZSTD compression algorithm
+
+At present, the data compression method in Apache Doris is uniformly specified by the system, and the default is LZ4. For some scenarios that are sensitive to data storage costs, the original data compression ratio requirements cannot be met.
+
+In version 1.1, users can set "compression"="zstd" in the table properties to specify the compression method as ZSTD when creating a table. In the 25GB 110 million lines of text log test data, the highest compression rate is nearly 10 times, which is 53% higher than the original compression rate, and the speed of reading data from disk and decompressing it is increased by 30%.
+
+## Improvements
+
+### More comprehensive vectorization support
+
+In version 1.1, we implemented full vectorization of the compute and storage layers, including:
+
+Implemented vectorization of all built-in functions
+
+The storage layer implements vectorization and supports dictionary optimization for low-cardinality string columns
+
+Optimized and resolved numerous performance and stability issues with the vectorization engine.
+
+We tested the performance of Apache Doris version 1.1 and version 0.15 on the SSB and TPC-H standard test datasets:
+
+On all 13 SQLs in the SSB test data set, version 1.1 is better than version 0.15, and the overall performance is improved by about 3 times, which solves the problem of performance degradation in some scenarios in version 1.0;
+
+On all 22 SQLs in the TPC-H test data set, version 1.1 is better than version 0.15, the overall performance is improved by about 4.5 times, and the performance of some scenarios is improved by more than ten times;

+
+### Compaction logic optimization and real-time guarantee
+
+In Apache Doris, each commit will generate a data version. In high concurrent write scenarios, -235 errors are prone to occur due to too many data versions and untimely compaction, and query performance will also decrease accordingly.
+
+In version 1.1, we introduced QuickCompaction, which will actively trigger compaction when the data version increases. At the same time, by improving the ability to scan fragment metadata, it can quickly find fragments with too many data versions and trigger compaction. Through active triggering and passive scanning, the real-time problem of data merging is completely solved.
+
+At the same time, for high-frequency small file cumulative compaction, the scheduling and isolation of compaction tasks is implemented to prevent the heavyweight base compaction from affecting the merging of new data.
+
+Finally, for the merging of small files, the strategy of merging small files is optimized, and the method of gradient merging is adopted. Each time the files participating in the merging belong to the same data magnitude, it prevents versions with large differences in size from merging, and gradually merges hierarchically. , reducing the number of times a single file participates in merging, which can greatly save the CPU consumption of the system.
+
+When the data upstream maintains a write frequency of 10w per second (20 concurrent write tasks, 5000 rows per job, and checkpoint interval of 1s), version 1.1 behaves as follows:
+
+-   Quick data consolidation: Tablet version remains below 50 and compaction score is stable. Compared with the -235 problem that frequently occurred during high concurrent writing in the previous version, the compaction merge efficiency has been improved by more than 10 times.
+
+-   Significantly reduced CPU resource consumption: The strategy has been optimized for small file Compaction. In the above scenario of high concurrent writing, CPU resource consumption is reduced by 25%;
+
+-   Stable query time consumption: The overall orderliness of data is improved, and the fluctuation of query time consumption is greatly reduced. The query time consumption during high concurrent writing is the same as that of only querying, and the query performance is improved by 3-4 times compared with the previous version.
+
+### Read efficiency optimization for Parquet and ORC files
+
+By adjusting arrow parameters, arrow's multi-threaded read capability is used to speed up Arrow's reading of each row_group, and it is modified to SPSC model to reduce the cost of waiting for the network through prefetching. After optimization, the performance of Parquet file import is improved by 4 to 5 times.
+
+### Safer metadata Checkpoint
+
+By double-checking the image files generated after the metadata checkpoint and retaining the function of historical image files, the problem of metadata corruption caused by image file errors is solved.
+
+## Bugfix
+
+### Fix the problem that the data cannot be queried due to the missing data version.(Serious)
+
+This issue was introduced in version 1.0 and may result in the loss of data versions for multiple replicas.
+
+### Fix the problem that the resource isolation is invalid for the resource usage limit of loading tasks (Moderate)
+
+In 1.1, the broker load and routine load will use Backends with specified resource tags to do the load.
+
+### Use HTTP BRPC to transfer network data packets over 2GB (Moderate)
+
+In the previous version, when the data transmitted between Backends through BRPC exceeded 2GB,
+it may cause data transmission errors.
+
+## Others
+
+### Disabling Mini Load
+
+The `/_load` interface is disabled by default, please use `the /_stream_load` interface uniformly.
+Of course, you can re-enable it by turning off the FE configuration item `disable_mini_load`.
+
+The Mini Load interface will be completely removed in version 1.2.
+
+### Completely disable the SegmentV1 storage format
+
+Data in SegmentV1 format is no longer allowed to be created. Existing data can continue to be accessed normally.
+You can use the `ADMIN SHOW TABLET STORAGE FORMAT` statement to check whether the data in SegmentV1 format
+still exists in the cluster. And convert to SegmentV2 through the data conversion command
+
+Access to SegmentV1 data will no longer be supported in version 1.2.
+
+### Limit the maximum length of String type
+
+In previous versions, String types were allowed a maximum length of 2GB.
+In version 1.1, we will limit the maximum length of the string type to 1MB. Strings longer than this length cannot be written anymore.
+At the same time, using the String type as a partitioning or bucketing column of a table is no longer supported.
+
+The String type that has been written can be accessed normally.
+
+### Fix fastjson related vulnerabilities
+
+Update to Canal version to fix fastjson security vulnerability.
+
+### Added `ADMIN DIAGNOSE TABLET` command
+
+Used to quickly diagnose problems with the specified tablet.

+## Features
+
+### Support ODBC Sink in Vectorized Engine.
+
+This feature is enabled in non-vectorized engine but it is missed in vectorized engine in 1.1. So that we add back this feature in 1.1.1.
+
+### Simple Memtracker for Vectorized Engine.
+
+There is no memtracker in BE for vectorized engine in 1.1, so that the memory is out of control and cause OOM. In 1.1.1, a simple memtracker is added to BE and could control the memory and cancel the query when memory exceeded.
+
+## Improvements
+
+### Cache decompressed data in page cache.
+
+Some data is compressed using bitshuffle and it costs a lot of time to decompress it during query. In 1.1.1, doris will decompress the data that encoded by bitshuffle to accelerate query and we find it could reduce 30% latency for some query in ssb-flat.
+
+## Bug Fix
+
+### Fix the problem that could not do rolling upgrade from 1.0.(Serious)
+
+This issue was introduced in version 1.1 and may cause BE core when upgrade BE but not upgrade FE.
+
+If you encounter this problem, you can try to fix it with [#10833](https://github.com/apache/doris/pull/10833).
+
+### Fix the problem that some query not fall back to non-vectorized engine, and BE will core.
+
+Currently, vectorized engine could not deal with all sql queries and some queries (like left outer join) will use non-vectorized engine to run. But there are some cases not covered in 1.1. And it will cause be crash.
+
+### Compaction not work correctly and cause -235 Error.
+
+One rowset multi segments in uniq key compaction, segments rows will be merged in generic_iterator but merged_rows not increased. Compaction will failed in check_correctness, and make a tablet with too much versions which lead to -235 load error.
+
+### Some segment fault cases during query.

+In this release, Doris Team has fixed more than 170 issues or performance improvement since 1.1.1. This release is a bugfix release on 1.1 and all users are encouraged to upgrade to this release.
+
+# Features
+
+### New MemTracker
+
+Introduced new MemTracker for both vectorized engine and non-vectorized engine which is more accurate.
+
+### Add API for showing current queries and kill query
+
+### Support read/write emoji of UTF16 via ODBC Table
+
+# Improvements
+
+### Data Lake related improvements
+
+- Improved HDFS ORC File scan performance about 300%. [#11501](https://github.com/apache/doris/pull/11501)
+
+- Support HDFS HA mode when query Iceberg table.
+
+- Support query Hive data created by [Apache Tez](https://tez.apache.org/)
+
+- Add Ali OSS as Hive external support.
+
+### Add support for string and text type in Spark Load
+
+
+### Add reuse block in non-vectorized engine and have 50% performance improvement in some cases. [#11392](https://github.com/apache/doris/pull/11392)
+
+### Improve like or regex performance
+
+### Disable tcmalloc's aggressive_memory_decommit 
+
+It will have 40% performance gains in load or query.
+
+Currently it is a config, you can change it by set config `tc_enable_aggressive_memory_decommit`.
+
+# Bug Fix
+
+### Some issues about FE that will cause FE failure or data corrupt.
+
+- Add reserved disk config to avoid too many reserved BDB-JE files.**(Serious)**   In an HA environment, BDB JE will retains as many reserved files. The BDB-je log doesn't delete until approaching a disk limit.
+
+- Fix fatal bug in BDB-JE which will cause FE replica could not start correctly or data corrupted.** (Serious)**
+
+### Fe will hang on waitFor_rpc during query and BE will hang in high concurrent scenarios.

+
+# Upgrade Notes
+
+PageCache and ChunkAllocator are disabled by default to reduce memory usage and can be re-enabled by modifying the configuration items `disable_storage_page_cache` and `chunk_reserved_bytes_limit`.
+
+Storage Page Cache and Chunk Allocator cache user data chunks and memory preallocation, respectively.
+
+These two functions take up a certain percentage of memory and are not freed. This part of memory cannot be flexibly allocated, which may lead to insufficient memory for other tasks in some scenarios, affecting system stability and availability. Therefore, we disabled these two features by default in version 1.1.3.
+
+However, in some latency-sensitive reporting scenarios, turning off this feature may lead to increased query latency. If you are worried about the impact of this feature on your business after upgrade, you can add the following parameters to be.conf to keep the same behavior as the previous version.
+
+```
+disable_storage_page_cache=false
+chunk_reserved_bytes_limit=10%
+```
+
+* ``disable_storage_page_cache``: Whether to disable Storage Page Cache. version 1.1.2 (inclusive), the default is false, i.e., on. version 1.1.3 defaults to true, i.e., off.
+* `chunk_reserved_bytes_limit`: Chunk allocator reserved memory size. 1.1.2 (and earlier), the default is 10% of the overall memory. 1.1.3 version default is 209715200 (200MB).

+
+# Behavior Changes
+
+When alias name is same as the original column name like "select year(birthday) as birthday" and use it in group by, order by , having clause, doris's behavior is different from MySQL in the past. In this release, we make it follow MySQL's behavior. Group by and having clause will use original column at first and order by will use alias first. It maybe a litter confuse here so there is a simple advice here, you'd better not use an alias the same as original column name.
+
+# Features
+
+Add support of murmur_hash3_64. [#14636](https://github.com/apache/doris/pull/14636)

+# Feature
+## Highlight
+
+1. Full Vectorizied-Engine support, greatly improved performance
+
+	In the standard ssb-100-flat benchmark, the performance of 1.2 is 2 times faster than that of 1.1; in complex TPCH 100 benchmark, the performance of 1.2 is 3 times faster than that of 1.1.
+
+2. Merge-on-Write Unique Key
+
+	Support Merge-On-Write on Unique Key Model. This mode marks the data that needs to be deleted or updated when the data is written, thereby avoiding the overhead of Merge-On-Read when querying, and greatly improving the reading efficiency on the updateable data model.
+
+3. Multi Catalog
+
+	The multi-catalog feature provides Doris with the ability to quickly access external data sources for access. Users can connect to external data sources through the `CREATE CATALOG` command. Doris will automatically map the library and table information of external data sources. After that, users can access the data in these external data sources just like accessing ordinary tables. It avoids the complicated operation that the user needs to manually establish external mapping for each table.
+    
+    Currently this feature supports the following data sources:
+    
+    1. Hive Metastore: You can access data tables including Hive, Iceberg, and Hudi. It can also be connected to data sources compatible with Hive Metastore, such as Alibaba Cloud's DataLake Formation. Supports data access on both HDFS and object storage.
+    2. Elasticsearch: Access ES data sources.
+    3. JDBC: Access MySQL through the JDBC protocol.
+    
+    Documentation: https://doris.apache.org//docs/dev/lakehouse/multi-catalog)
+
+    > Note: The corresponding permission level will also be changed automatically, see the "Upgrade Notes" section for details.
+    
+4. Light table structure changes
+
+In the new version, it is no longer necessary to change the data file synchronously for the operation of adding and subtracting columns to the data table, and only need to update the metadata in FE, thus realizing the millisecond-level Schema Change operation. Through this function, the DDL synchronization capability of upstream CDC data can be realized. For example, users can use Flink CDC to realize DML and DDL synchronization from upstream database to Doris.
+
+Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Definition-Statements/Create/CREATE-TABLE
+
+When creating a table, set `"light_schema_change"="true"` in properties.
+
+5. JDBC facade
+
+	Users can connect to external data sources through JDBC. Currently supported:
+
+	  - MySQL
+	  - PostgreSQL
+	  - Oracle
+	  - SQL Server
+	  - Clickhouse
+
+	Documentation: [https://doris.apache.org/en/docs/dev/lakehouse/multi-catalog/jdbc](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc/)
+
+	> Note: The ODBC feature will be removed in a later version, please try to switch to the JDBC.
+
+6. JAVA UDF
+
+	Supports writing UDF/UDAF in Java, which is convenient for users to use custom functions in the Java ecosystem. At the same time, through technologies such as off-heap memory and Zero Copy, the efficiency of cross-language data access has been greatly improved.
+
+	Document: https://doris.apache.org//docs/dev/ecosystem/udf/java-user-defined-function
+
+	Example: https://github.com/apache/doris/tree/master/samples/doris-demo
+	
+7. Remote UDF
+
+	Supports accessing remote user-defined function services through RPC, thus completely eliminating language restrictions for users to write UDFs. Users can use any programming language to implement custom functions to complete complex data analysis work.
+
+	Documentation: https://doris.apache.org//docs/ecosystem/udf/remote-user-defined-function
+
+	Example: https://github.com/apache/doris/tree/master/samples/doris-demo
+        
+8. More data types support
+
+	- Array type
+
+		Array types are supported. It also supports nested array types. In some scenarios such as user portraits and tags, the Array type can be used to better adapt to business scenarios. At the same time, in the new version, we have also implemented a large number of data-related functions to better support the application of data types in actual scenarios.
+
+	Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Types/ARRAY
+
+	Related functions: https://doris.apache.org//docs/dev/sql-manual/sql-functions/array-functions/array_max
+        
+	- Jsonb type
+
+		Support binary Json data type: Jsonb. This type provides a more compact json encoding format, and at the same time provides data access in the encoding format. Compared with json data stored in strings, it is several times newer and can be improved.
+
+	Documentation: https://doris.apache.org//docs/dev/sql-manual/sql-reference/Data-Types/JSONB
+
+	Related functions: https://doris.apache.org//docs/dev/sql-manual/sql-functions/json-functions/jsonb_parse
+          
+	- Date V2
+	
+		Sphere of influence:
+
+		1. The user needs to specify datev2 and datetimev2 when creating the table, and the date and datetime of the original table will not be affected.
+		2. When datev2 and datetimev2 are calculated with the original date and datetime (for example, equivalent connection), the original type will be cast into a new type for calculation
+		3. The example is in the documentation
+
+		Documentation: https://doris.apache.org/docs/1.2/sql-manual/sql-reference/Data-Types/DATEV2
+	 
+	 
+## More
+
+1. A new memory management framework
+
+	Documentation: https://doris.apache.org//docs/dev/admin-manual/maint-monitor/memory-management/memory-tracker
+
+2. Table Valued Function
+
+	Doris implements a set of Table Valued Function (TVF). TVF can be regarded as an ordinary table, which can appear in all places where "table" can appear in SQL.
+
+	For example, we can use S3 TVF to implement data import on object storage:
+
+	```
+	insert into tbl select * from s3("s3://bucket/file.*", "ak" = "xx", "sk" = "xxx") where c1 > 2;
+	```
+
+	Or directly query data files on HDFS:
+	
+	```
+	insert into tbl select * from hdfs("hdfs://bucket/file.*") where c1 > 2;
+	```
+	
+	TVF can help users make full use of the rich expressiveness of SQL and flexibly process various data.

+# Upgrade Notice
+
+## Known Issues
+
+- Use JDK11 will cause BE crash, please use JDK8 instead.
+
+## Behavior Changed
+
+- Permission level changes
+
+	Because the catalog level is introduced, the corresponding user permission level will also be changed automatically. The rules are as follows:
+	
+	- GlobalPrivs and ResourcePrivs remain unchanged
+	- Added CatalogPrivs level.
+	- The original DatabasePrivs level is added with the internal prefix (indicating the db in the internal catalog)
+	- Add the internal prefix to the original TablePrivs level (representing tbl in the internal catalog)
+
+- In GroupBy and Having clauses, match on column names in preference to aliases. (#14408)
+
+- Creating columns starting with `mv_` is no longer supported. `mv_` is a reserved keyword in materialized views (#14361)
+
+- Removed the default limit of 65535 rows added by the order by statement, and added the session variable `default_order_by_limit` to configure this limit. (#12478)
+
+- In the table generated by "Create Table As Select", all string columns use the string type uniformly, and no longer distinguish varchar/char/string (#14382)
+
+- In the audit log, remove the word `default_cluster` before the db and user names. (#13499) (#11408)
+
+- Add sql digest field in audit log (#8919)
+
+- The union clause always changes the order by logic. In the new version, the order by clause will be executed after the union is executed, unless explicitly associated by parentheses. (#9745)
+
+- During the decommission operation, the tablet in the recycle bin will be ignored to ensure that the decomission can be completed. (#14028)
+
+- The returned result of Decimal will be displayed according to the precision declared in the original column, or according to the precision specified in the cast function. (#13437)
+
+- Changed column name length limit from 64 to 256 (#14671)
+
+- Changes to FE configuration items
+
+  - The `enable_vectorized_load` parameter is enabled by default. (#11833)
+
+  - Increased `create_table_timeout` value. The default timeout for table creation operations will be increased. (#13520)
+
+  - Modify `stream_load_default_timeout_second` default value to 3 days.
+
+  - Modify the default value of `alter_table_timeout_second` to one month.
+
+  - Increase the parameter `max_replica_count_when_schema_change` to limit the number of replicas involved in the alter job, the default is 100000. (#12850)
+
+  - Add `disable_iceberg_hudi_table`. The iceberg and hudi appearances are disabled by default, and the multi catalog function is recommended. (#13932)
+
+- Changes to BE configuration items
+
+  - Removed `disable_stream_load_2pc` parameter. 2PC's stream load can be used directly. (#13520)
+
+  - Modify `tablet_rowset_stale_sweep_time_sec` from 1800 seconds to 300 seconds.
+
+  - Redesigned configuration item name about compaction (#13495)
+
+  - Revisited parameter about memory optimization (#13781)
+
+- Session variable changes
+
+   - Modify the variable `enable_insert_strict` to true by default. This will cause some insert operations that could be executed before, but inserted illegal values, to no longer be executed. (11866)
+
+   - Modified variable `enable_local_exchange` to default to true (#13292)
+
+   - Default data transmission via lz4 compression, controlled by variable `fragment_transmission_compression_codec` (#11955)
+
+   - Add `skip_storage_engine_merge` variable for debugging unique or agg model data (#11952)
+    
+     Documentation: https://doris.apache.org//docs/dev/advanced/variables
+
+- The BE startup script will check whether the value is greater than 200W through `/proc/sys/vm/max_map_count`. Otherwise, the startup fails. (#11052)
+
+- Removed mini load interface (#10520)
+
+- FE Metadata Version
+
+	FE Meta Version changed from 107 to 114, and cannot be rolled back after upgrading.
+	
+## During Upgrade
+
+1. Upgrade preparation
+  
+   - Need to replace: lib, bin directory (start/stop scripts have been modified)
+  
+   - BE also needs to configure JAVA_HOME, and already supports JDBC Table and Java UDF.
+  
+   - The default JVM Xmx parameter in fe.conf is changed to 8GB.
+
+2. Possible errors during the upgrade process
+  
+   - The repeat function cannot be used and an error is reported: `vectorized repeat function cannot be executed`, you can turn off the vectorized execution engine before upgrading. (#13868)
+  
+   - schema change fails with error: `desc_tbl is not set. Maybe the FE version is not equal to the BE` (#13822)
+  
+   - Vectorized hash join cannot be used and an error will be reported. `vectorized hash join cannot be executed`. You can turn off the vectorized execution engine before upgrading. (#13753)
+
+	The above errors will return to normal after a full upgrade.
+	
+## Performance Impact
+
+- By default, JeMalloc is used as the memory allocator of the new version BE, replacing TcMalloc (#13367)

+
+# Upgrade Notice
+
+### Known Issues
+
+- Do not use JDK11 as the runtime JDK of BE, it will cause BE Crash.
+- The reading performance of the csv format in this version has declined, which will affect the import and reading efficiency of the csv format. We will fix it as soon as possible in the next three-digit version
+
+### Behavior Changed
+
+- The default value of the BE configuration item `high_priority_flush_thread_num_per_store` is changed from 1 to 6, to improve the write efficiency of Routine Load. (https://github.com/apache/doris/pull/14775)
+
+- The default value of the FE configuration item `enable_new_load_scan_node` is changed to true. Import tasks will be performed using the new File Scan Node. No impact on users.[#14808](https://github.com/apache/doris/pull/14808)
+
+- Delete the FE configuration item `enable_multi_catalog`. The Multi-Catalog function is enabled by default.
+
+- The vectorized execution engine is forced to be enabled by default.[#15213](https://github.com/apache/doris/pull/15213)
+
+The session variable enable_vectorized_engine will no longer take effect. Enabled by default.
+
+To make it valid again, set the FE configuration item `disable_enable_vectorized_engine` to false, and restart FE to make `enable_vectorized_engine` valid again.

+
+- Hive Metastore metadata automatic synchronization supports notification event in compressed format.
+
+### Dynamic Partition Improvement
+
+- Dynamic partition supports specifying the `storage_medium` parameter to control the storage medium of the newly added partition.
+
+Reference: [https://doris.apache.org/docs/dev/advanced/partition/dynamic-partition](https://doris.apache.org/docs/dev/advanced/partition/dynamic-partition)

+# Behavior Changed
+
+- For `DateV2`/`DatetimeV2` and `DecimalV3` type, in the results of `DESCRIBLE` and `SHOW CREATE TABLE` statements, they will no longer be displayed as `DateV2`/`DatetimeV2` or `DecimalV3`, but directly displayed as `Date`/`Datetime` or `Decimal`.
+
+	- This change is for compatibility with some BI tools. If you want to see the actual type of the column, you can check it with the `DESCRIBE ALL` statement.
+
+- When querying tables in the `information_schema` database, the meta information(database, table, column, etc.) in the external catalog is no longer returned by default.
+
+	- This change avoids the problem that the `information_schema` database cannot be queried due to the connection problem of some external catalog, so as to solve the problem of using some BI tools with Doris. It can be controlled by the FE configuration  `infodb_support_ext_catalog`, and the default value is `false`, that is, the meta information of external catalog will not be returned.
+
+# Improvement
+
+### JDBC Catalog
+
+- Supports connecting to Trino/Presto via JDBC Catalog
+
+​        Refer to: [https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino)
+
+- JDBC Catalog connects to Clickhouse data source and supports Array type mapping
+
+​        Refer to: [https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#clickhouse](https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#clickhouse)
+
+### Spark Load 
+
+- Spark Load supports Resource Manager HA related configuration
+
+​        Refer to: https://github.com/apache/doris/pull/15000
+
+## Bug Fixes
+
+- Fixed several connectivity issues with Hive Catalog.
+
+- Fixed ClassNotFound issues with Hudi Catalog.
+

+
+- Fix the problem that OOM will occur when importing data from another Doris cluster through JDBC Catalog.
+
+- Fixed serveral queries and imports planning issues.
+
+- Fixed several issues with Unique Key Merge-On-Write data model.
+

+
+In version 1.2.5, the Doris team has fixed nearly 210 issues or performance improvements since the release of version 1.2.4. At the same time, version 1.2.5 is also an iterative version of version 1.2.4, which has higher stability. It is recommended that all users upgrade to this version.
+
+# Behavior Changed
+
+- The `start_be.sh` script will check that the maximum number of file handles in the system must be greater than or equal to 65536, otherwise the startup will fail.
+
+- The BE configuration item `enable_quick_compaction` is set to true by default. The Quick Compaction is enabled by default. This feature is used to optimize the problem of small files in the case of large batch import.
+
+- After modifying the dynamic partition attribute of the table, it will no longer take effect immediately, but wait for the next task scheduling of the dynamic partition table to avoid some deadlock problems.
+
+# Improvement
+
+- Optimize the use of bthread and pthread to reduce the RPC blocking problem during the query process.
+
+- A button to download Profile is added to the Profile page of the FE web UI.
+
+- Added FE configuration `recover_with_skip_missing_version`, which is used to query to skip the problematic replica under certain failure conditions.
+
+- The row-level permission function supports external Catalog.
+
+- Hive Catalog supports automatic refreshing of kerberos tickets on the BE side without manual refreshing.
+
+- JDBC Catalog supports tables under the MySQL/ClickHouse system database (`information_schema`).
+
+# Bug Fixes
+
+- Fixed the problem of incorrect query results caused by low-cardinality column optimization
+
+- Fixed several authentication and compatibility issues accessing HDFS.
+
+- Fixed several issues with float/double and decimal types.
+
+- Fixed several issues with date/datetimev2 types.
+
+- Fixed several query execution and planning issues.
+
+- Fixed several issues with JDBC Catalog.
+
+- Fixed several query-related issues with Hive Catalog, and Hive Metastore metadata synchronization issues.
+
+- Fix the problem that the result of `SHOW LOAD PROFILE` statement is incorrect.
+
+- Fixed several memory related issues.
+
+- Fixed several issues with `CREATE TABLE AS SELECT` functionality.
+
+- Fix the problem that the jsonb type causes BE to crash on CPU that do not support avx2.
+
+- Fixed several issues with dynamic partitions.
+
+- Fixed several issues with TOPN query optimization.
+
+- Fixed several issues with the Unique Key Merge-on-Write table model.

+
+## **A 10 Times Performance Increase**
+
+In SSB-Flat and TPC-H benchmarking, Apache Doris 2.0.0 delivered **over 10-time faster query performance** compared to an early version of Apache Doris.
+
+![](/images/release-note-2.0.0-1.png)
+
+This is realized by the introduction of a smarter query optimizer, inverted index, a parallel execution model, and a series of new functionalities to support high-concurrency point queries.
+
+### A smarter query optimizer
+
+The brand new query optimizer, Nereids, has a richer statistical base and adopts the Cascades framework. It is capable of self-tuning in most query scenarios and supports all 99 SQLs in TPC-DS, so users can expect high performance without any fine-tuning or SQL rewriting.
+
+TPC-H tests showed that Nereids, with no human intervention, outperformed the old query optimizer by a wide margin. Over 100 users have tried Apache Doris 2.0.0 in their production environment and the vast majority of them reported huge speedups in query execution.
+
+![](/images/release-note-2.0.0-2.png)
+
+**Doc**: https://doris.apache.org/docs/dev/query-acceleration/nereids/
+
+Nereids is enabled by default in Apache Doris 2.0.0: `SET enable_nereids_planner=true`. Nereids collects statistical data by calling the Analyze command.
+
+### Inverted Index
+
+In Apache Doris 2.0.0, we introduced inverted index to better support fuzzy keyword search, equivalence queries, and range queries.
+
+A smartphone manufacturer tested Apache Doris 2.0.0 in their user behavior analysis scenarios. With inverted index enabled, v2.0.0 was able to finish the queries within milliseconds and maintain stable performance as the query concurrency level went up. In this case, it is 5 to 90 times faster than its old version. 
+
+![](/images/release-note-2.0.0-3.png)
+
+### 20 times higher concurrency capability
+
+In scenarios like e-commerce order queries and express tracking, a huge number of end data users search for a certain data record simultaneously. These are what we call high-concurrency point queries, which can bring huge pressure on the system. A traditional solution is to introduce Key-Value stores like Apache HBase for such queries, and Redis as a cache layer to ease the burden, but that means redundant storage and higher maintenance costs.
+
+For a column-oriented DBMS like Apache Doris, the I/O usage of point queries will be multiplied. We need neater execution. Thus, on the basis of columnar storage, we added row storage format and row cache to increase row reading efficiency, short-circuit plans to speed up data retrieval, and prepared statements to reduce frontend overheads.
+
+After these optimizations, Apache Doris 2.0 reached a concurrency level of **30,000 QPS per node** on YCSB on a 16 Core 64G cloud server with 4×1T hard drives, representing an improvement of **20 times** compared to its older version. This makes Apache Doris a good alternative to HBase in high-concurrency scenarios, so that users don't need to endure extra maintenance costs and redundant storage brought by complicated tech stacks.
+
+Read more: https://doris.apache.org/blog/High_concurrency
+
+### A self-adaptive parallel execution model
+
+Apache 2.0 brought in a Pipeline execution model for higher efficiency and stability in hybrid analytic workloads. In this model, the execution of queries is driven by data. The blocking operators in all query execution processes are split into pipelines. Whether a pipeline gets an execution thread depends on whether its relevant data is ready. This enables asynchronous blocking operations and more flexible system resource management. Also, this improves CPU efficiency as the system doesn't have to create and destroy threads that much.
+
+Doc: https://doris.apache.org/docs/dev/query-acceleration/pipeline-execution-engine/
+
+**How to enable the Pipeline execution model**
+
+- The Pipeline execution engine is enabled by default in Apache Doris 2.0: `Set enable_pipeline_engine = true`.
+- `parallel_pipeline_task_num` represents the number of pipeline tasks that are parallelly executed in SQL queries. The default value of it is `0`, which means Apache Doris will automatically set the concurrency level to half the number of CPUs in each backend node. Users can change this value as they need it. 
+- For those who are upgrading to Apache Doris 2.0 from an older version, it is recommended to set the value of `parallel_pipeline_task_num` to that of `parallel_fragment_exec_instance_num` in the old version.
+
+## A Unified Platform for Multiple Analytic Workloads
+
+Apache Doris has been pushing its boundaries. Starting as an OLAP engine for reporting, it is now a data warehouse capable of ETL/ELT and more. Version 2.0 is making advancements in its log analysis and data lakehousing capabilities.  
+
+### A 10 times more cost-effective log analysis solution
+
+Apache Doris 2.0.0 provides native support for semi-structured data. In addition to JSON and Array, it now supports a complex data type: Map. Based on Light Schema Change, it also supports Schema Evolution, which means you can adjust the schema as your business changes. You can add or delete fields and indexes, and change the data types for fields. As we introduced inverted index and a high-performance text analysis algorithm into it, it can execute full-text search and dimensional analysis of logs more efficiently. With faster data writing and query speed and lower storage cost, it is 10 times more cost-effective than the common log analytic solution within the industry.
+
+![](/images/release-note-2.0.0-4.png)
+
+### Enhanced data lakehousing capabilities
+
+In Apache Doris 1.2, we introduced Multi-Catalog to allow for auto-mapping and auto-synchronization of data from heterogeneous sources. In version 2.0.0, we extended the list of data sources supported and optimized Doris for based on users' needs in production environment.
+
+![](/images/release-note-2.0.0-5.png)
+
+Apache Doris 2.0.0 supports dozens of data sources including Hive, Hudi, Iceberg, Paimon, MaxCompute, Elasticsearch, Trino, ClickHouse, and almost all open lakehouse formats. It also supports snapshot queries on Hudi Copy-on-Write tables and read optimized queries on Hudi Merge-on-Read tables. It allows for authorization of Hive Catalog using Apache Ranger, so users can reuse their existing privilege control system. Besides, it supports extensible authorization plug-ins to enable user-defined authorization methods for any catalog. 
+
+TPC-H benchmark tests showed that Apache Doris 2.0.0 is 3~5 times faster than Presto/Trino in queries on Hive tables. This is realized by all-around optimizations (in small file reading, flat table reading, local file cache, ORC/Parquet file reading, Compute Nodes, and information collection of external tables) finished in this development cycle and the distributed execution framework, vectorized execution engine, and query optimizer of Apache Doris. 
+
+![](/images/release-note-2.0.0-6.png)
+
+All this gives Apache Doris 2.0.0 an edge in data lakehousing scenarios. With Doris, you can do incremental or overall synchronization of multiple upstream data sources in one place, and expect much higher data query performance than other query engines. The processed data can be written back to the sources or provided for downstream systems. In this way, you can make Apache Doris your unified data analytic gateway.
+
+## Efficient Data Update
+
+Data update is important in real-time analysis, since users want to always be accessible to the latest data, and be able to update data flexibly, such as updating a row or just a few columns, batching updating or deleting their specified data, or even overwriting a whole data partition.
+
+Efficient data updating has been another hill to climb in data analysis. Apache Hive only supports updates on the partition level, while Hudi and Iceberg do better in low-frequency batch updates instead of real-time updates due to their Merge-on-Read and Copy-on-Write implementations.
+
+As for data updating, Apache Doris 2.0.0 is capable of:
+
+- **Faster data writing**: In the pressure tests with an online payment platform, under 20 concurrent data writing tasks, Doris reached a writing throughput of 300,000 records per second and maintained stability throughout the over 10-hour continuous writing process.
+- **Partial column update**: Older versions of Doris implements partial column update by `replace_if_not_null` in the Aggregate Key model. In 2.0.0, we enable partial column updates in the Unique Key model. That means you can directly write data from multiple source tables into a flat table, without having to concatenate them into one output stream using Flink before writing. This method avoids a complicated processing pipeline and the extra resource consumption. You can simply specify the columns you need to update.
+- **Conditional update and deletion**: In addition to the simple Update and Delete operations, we realize complicated conditional updates and deletes operations on the basis of Merge-on-Write. 
+
+## Faster, Stabler, and Smarter Data Writing
+
+### Higher speed in data writing
+
+As part of our continuing effort to strengthen the real-time analytic capability of Apache Doris, we have improved the end-to-end real-time data writing capability of version 2.0.0. Benchmark tests reported higher throughput in various writing methods:
+
+- Stream Load, TPC-H 144G lineitem table, 48-bucket Duplicate table, triple-replica writing: throughput increased by 100%
+- Stream Load, TPC-H 144G lineitem table, 48-bucket Unique Key table, triple-replica writing: throughput increased by 200%
+- Insert Into Select, TPC-H 144G lineitem table, 48-bucket Duplicate table: throughput increased by 50%
+- Insert Into Select, TPC-H 144G lineitem table, 48-bucket Unique Key table: throughput increased by 150%
+
+### Greater stability in high-concurrency data writing 
+
+The sources of system instability often includes small file merging, write amplification, and the consequential disk I/O and CPU overheads. Hence, we introduced Vertical Compaction and Segment Compaction in version 2.0.0 to eliminate OOM errors in compaction and avoid the generation of too many segment files during data writing. After such improvements, Apache Doris can write data 50% faster while **using only 10% of the memory that it previously used**.
+
+Read more: https://doris.apache.org/blog/Compaction
+
+### Auto-synchronization of table schema
+
+The latest Flink-Doris-Connector allows users to synchronize an entire database (such as MySQL and Oracle) to Apache Doris by one simple step. According to our test results, one single synchronization task can support the real-time concurrent writing of thousands of tables. Users no longer need to go through a complicated synchronization procedure because Apache Doris has automated the process. Changes in the upstream data schema will be automatically captured and dynamically updated to Apache Doris in a seamless manner.

+
+## A New Multi-Tenant Resource Isolation Solution
+
+The purpose of multi-tenant resource isolation is to avoid resource preemption in the case of heavy loads. For that sake, older versions of Apache Doris adopted a hard isolation plan featured by Resource Group: Backend nodes of the same Doris cluster would be tagged, and those of the same tag formed a Resource Group. As data was ingested into the database, different data replicas would be written into different Resource Groups, which will be responsible for different workloads. For example, data reading and writing will be conducted on different data tablets, so as to realize read-write separation. Similarly, you can also put online and offline business on different Resource Groups. 
+
+![](/images/release-note-2.0.0-7.png)
+
+This is an effective solution, but in practice, it happens that some Resource Groups are heavily occupied while others are idle. We want a more flexible way to reduce vacancy rate of resources. Thus, in 2.0.0, we introduce Workload Group resource soft limit.
+
+![](/images/release-note-2.0.0-8.png)
+
+The idea is to divide workloads into groups to allow for flexible management of CPU and memory resources. Apache Doris associates a query with a Workload Group, and limits the percentage of CPU and memory that a single query can use on a backend node. The memory soft limit can be configured and enabled by the user. 
+
+When there is a cluster resource shortage, the system will kill the largest memory-consuming query tasks; when there are sufficient cluster resources, once a Workload Group uses more resources than expected, the idle cluster resources will be shared among all the Workload Groups to give full play to the system memory and ensure stable execution of queries. You can also prioritize the Workload Groups in terms of resource allocation. In other words, you can decide which tasks can be assigned with adequate resources and which not.
+
+Meanwhile, we introduced Query Queue in 2.0.0. Upon Workload Group creation, you can set a maximum query number for a query queue. Queries beyond that limit will wait for execution in the queue. This is to reduce system burden under heavy workloads.
+
+## Elastic Scaling and Storage-Compute Separation
+
+When it comes to computation and storage resources, what do users want?
+
+- **Elastic scaling of computation resources**: Scale up resources quickly in peak times to increase efficiency and scale down in valley times to reduce costs.
+- **Lower storage costs**: Use low-cost storage media and separate storage from computation.
+- **Separation of workloads**: Isolate the computation resources of different workloads to avoid preemption.
+- **Unified management of data**: Simply manage catalogs and data in one place.
+
+To separate storage and computation is a way to realize elastic scaling of resources, but it demands more efforts in maintaining storage stability, which determines the stability and continuity of OLAP services. To ensure storage stability, we introduced mechanisms including cache management, computation resource management, and garbage collection.
+
+ In this respect, we divide our users into three groups after investigation:
+
+1. Users with no need for resource scaling
+2. Users requiring resource scaling, low storage costs, and workload separation from Apache Doris
+3. Users who already have a stable large-scale storage system and thus require an advanced compute-storage-separated architecture for efficient resource scaling
+
+Apache Doris 2.0 provides two solutions to address the needs of the first two types of users.
+
+1. **Compute nodes**. We introduced stateless compute nodes in version 2.0. Unlike the mix nodes, the compute nodes do not save any data and are not involved in workload balancing of data tablets during cluster scaling. Thus, they are able to quickly join the cluster and share the computing pressure during peak times. In addition, in data lakehouse analysis, these nodes will be the first ones to execute queries on remote storage (HDFS/S3) so there will be no resource competition between internal tables and external tables.
+   1.  Doc: https://doris.apache.org/docs/dev/advanced/compute_node/
+2. **Hot-cold data separation**. Hot/cold data refers to data that is frequently/seldom accessed, respectively. Generally, it makes more sense to store cold data in low-cost storage. Older versions of Apache Doris support lifecycle management of table partitions: As hot data cooled down, it would be moved from SSD to HDD. However, data was stored with multiple replicas on HDD, which was still a waste. Now, in Apache Doris 2.0, cold data can be stored in object storage, which is even cheaper and allows single-copy storage. That reduces the storage costs by 70% and cuts down the computation and network overheads that come with storage.
+   1.  Read more: https://doris.apache.org/blog/HCDS/
+
+For neater separate of computation and storage, the VeloDB team is going to contribute the Cloud Compute-Storage-Separation solution to the Apache Doris project. The performance and stability of it has stood the test of hundreds of companies in their production environment. The merging of code will be finished by October this year, and all Apache Doris users will be able to get an early taste of it in September.
+
+## Enhanced Usability
+
+Apache Doris 2.0.0 also highlights some enterprise-facing functionalities.
+
+### Support for Kubernetes Deployment
+
+Older versions of Apache Doris communicate based on IP, so any host failure in Kubernetes deployment that causes a POD IP drift will lead to cluster unavailability. Now, version 2.0 supports FQDN. That means the failed Doris nodes can recover automatically without human intervention, which lays the foundation for Kubernetes deployment and elastic scaling.  
+
+### Support for Cross-Cluster Replication (CCR)
+
+Apache Doris 2.0.0 supports cross-cluster replication (CCR). Data changes at the database/table level in the source cluster will be synchronized to the target cluster. You can choose to replicate the incremental data or the overall data. 
+
+It also supports synchronization of DDL, which means DDL statements executed by the source cluster can also by automatically replicated to the target cluster. 
+
+It is simple to configure and use CCR in Doris. Leveraging this functionality, you can implement read-write separation and multi-datacenter replication 
+
+This feature allows for higher availability of data, read/write workload separation, and cross-data-center replication more efficiently.
+
+## Behavior Change
+
+- Use rolling upgrade from 1.2-ITS to 2.0.0, and restart upgrade from preview versions of 2.0 to 2.0.0;
+- The new query optimizer (Nereids) is enabled by default: `enable_nereids_planner=true`;
+- All non-vectorized code has been removed from the system, so the `enable_vectorized_engine` parameter no long works;
+- A new parameter `enable_single_replica_compaction` has been added;
+- datev2, datetimev2, and decimalv3 are the default data types in table creation; datav1, datetimev1, and decimalv2 are not supported in table creation;
+- decimalv3 is the default data type for JDBC and Iceberg Catalog;
+- A new data type `AGG_STATE` has been added;
+- The cluster column has been removed from backend tables;
+- For better compatibility with BI tools, datev2 and datetimev2 are displayed as date and datetime when `show create table`;
+- max_openfiles and swaps checks are added to the backend startup script so inappropriate system configuration might lead to backend failure;
+- Password-free login is not allowed when accessing frontend on localhost;
+- If there is a Multi-Catalog in the system, by default, only data of the internal catalog will be displayed when querying information schema;
+- A limit has been imposed on the depth of the expression tree. The default value is 200;
+- The single quote in the return value of array string has been changed to double quote;
+- The Doris processes are renamed to DorisFE and DorisBE.
+- The functions AES and SM4 with two arguments' behaviour changed. See more informations in [relative function docs](../../sql-manual/sql-functions/encrypt-digest-functions/sm4-encrypt.md)
+
+## Embarking on the 2.0.0 Journey
+
+To make Apache Doris 2.0.0 production-ready, we invited hundreds of enterprise users to engage in the testing and optimized it for better performance, stability, and usability. In the next phase, we will continue responding to user needs with agile release planning. We plan to launch 2.0.1 in late August and 2.0.2 in September, as we keep fixing bugs and adding new features. We also plan to release an early version of 2.1 in September to bring a few long-requested capabilities to you. For example, in Doris 2.1, the Variant data type will better serve the schema-free analytic needs of semi-structured data; the multi-table materialized views will be able to simplify the data scheduling and processing link while speeding up queries; more and neater data ingestion methods will be added and nested composite data types will be realized.
+
+If you have any questions or ideas when investigating, testing, and deploying Apache Doris, please find us on [Slack](https://t.co/ZxJuNJHXb2). Our developers will be happy to hear them and provide targeted support.

+## Improvement and Optimizations
+
+- This enhancement introduces the `read_only` and `super_read_only` variables to the database system, ensuring compatibility with MySQL's read-only modes.
+
+- When the check status is not IO_ERROR, the disk path should not be added to the broken list. This ensures that only disks with actual I/O errors are marked as broken.
+
+- When performing a Create Table As Select (CTAS) operation from an external table, convert the `VARCHAR` column to `STRING` type.
+
+- Support mapping Paimon column type "ROW" to Doris type "STRUCT"
+
+- Choose disk tolerate with little skew when creating tablet
+
+- Write editlog to `set replica drop` to avoid confusing status on follower FE
+
+- Make the schema change memory space adaptive to avoid memory over limit
+
+- Inverted index 'unicode' tokenizer supports configuration to exclude stop words
+

+
+## 1 Behavior change
+
+Since the inverted index is now mature and stable, it can replace the old BITMAP INDEX. Therefore, any newly created `BITMAP INDEX` will automatically switch to an `INVERTED INDEX`, while existing `BITMAP INDEX` will remain unchanged. This entire switching process is transparent to the user, with no changes to writing or querying. Additionally, users can disable this automatic switch by setting the FE configuration `enable_create_bitmap_index_as_inverted_index` to false. [#35528](https://github.com/apache/doris/pull/35528)
+
+
+## 2 Improvement and optimizations
+
+- Add Trino JDBC Catalog type mapping for JSON and TIME
+
+- FE exit when failed to transfer to (non) master to prevent unknown state and too many logs
+
+- Write audit log while doing drop stats table.
+
+- Ignore min/max column stats if table is partially analyzed to avoid inefficient query plan
+
+- Support minus operation for set like `set1 - set2`
+
+- Improve perfmance of LIKE and REGEXP clause with concat (col, pattern_str), eg. `col1 LIKE concat('%', col2, '%')`
+
+- Add query options for short circuit queries for upgrade compatibility

+
+## Behavior changes
+
+- No longer set the default table comment to the table type. Instead, set it to be empty by default, for example, change COMMENT 'OLAP' to COMMENT ' '.  This new behavior is more friendly for BI software that relies on table comments. [#35855](https://github.com/apache/doris/pull/35855)
+
+- Change the type of the `@@autocommit` variable from `BOOLEAN` to `BIGINT` to prevent errors from certain MySQL clients (such as .NET MySQL.Data). [#33282](https://github.com/apache/doris/pull/33282)
+
+
+## Improvements
+
+- Remove the `disable_nested_complex_type` parameter and allow the creation of nested `ARRAY`, `MAP`, and `STRUCT` types by default. [#36255](https://github.com/apache/doris/pull/36255)
+
+- The HMS catalog supports the `SHOW CREATE DATABASE` command. [#28145](https://github.com/apache/doris/pull/28145)
+
+- Add more inverted index metrics to the query profile. [#36545](https://github.com/apache/doris/pull/36545)
+
+- Cross-Cluster Replication (CCR) supports inverted indices. [#31743](https://github.com/apache/doris/pull/31743)

+
+## Behavior changes
+
+SQL input is treated as multiple statements only when the `CLIENT_MULTI_STATEMENTS` setting is enabled on the client side, enhancing compatibility with MySQL. [#36759](https://github.com/apache/doris/pull/36759)
+
+## New features
+
+- A new BE configuration `allow_zero_date` has been added, allowing dates with all zeros. When set to `false`, `0000-00-00` is parsed as `NULL`, and when set to `true`, it is parsed as `0000-01-01`. The default value is `false` to maintain consistency with previous behavior. [#34961](https://github.com/apache/doris/pull/34961)
+
+- `LogicalWindow` and `LogicalPartitionTopN` support multi-field predicate pushdown to improve performance. [#36828](https://github.com/apache/doris/pull/36828)
+
+- The ES Catalog now maps ES `nested` or `object` types to Doris `JSON` types. [#37101](https://github.com/apache/doris/pull/37101)
+
+## Improvements
+
+- Queries with `LIMIT` end reading data earlier to reduce resource consumption and improve performance. [#36535](https://github.com/apache/doris/pull/36535)
+
+- Special JSON data with empty keys is now supported. [#36762](https://github.com/apache/doris/pull/36762)
+
+- Stability and usability of routine load have been improved, including load balancing, automatic recovery, exception handling, and more user-friendly error messages.

+
+Thanks to our community users and developers, about 1000 improvements and bug fixes have been made in Doris 2.0.3 version, including optimizer statistics, inverted index, complex datatypes, data lake, replica management.
+
+
+
+## 1 Behavior change
+
+- The output format of the complex data type array/map/struct has been changed to be consistent to the input format and JSON specification. The main changes from the previous version are that DATE/DATETIME and STRING/VARCHAR are enclosed in double quotes and null values inside ARRAY/MAP are displayed as `null` instead of `NULL`.
+  - https://github.com/apache/doris/pull/25946
+- SHOW_VIEW permission is supported. Users with SELECT or LOAD permission will no longer be able to execute the 'SHOW CREATE VIEW' statement and must be granted the SHOW_VIEW permission separately.
+  - https://github.com/apache/doris/pull/25370
+
+
+## 2 New features
+
+### 2.1 Support collecting statistics for optimizer automatically
+
+Collecting statistics helps the optimizer understand the data distribution characteristics and choose a better plan to greatly improve query performance. It is officially supported starting from version 2.0.3 and is enabled all day by default.
+
+### 2.2 Support complex datatypes for more datalake source
+- Support complex datatypes for JAVA UDF, JDBC and Hudi MOR
+  - https://github.com/apache/doris/pull/24810
+  - https://github.com/apache/doris/pull/26236
+- Support complex datatypes for Paimon
+  - https://github.com/apache/doris/pull/25364
+- Suport Paimon version 0.5
+  - https://github.com/apache/doris/pull/24985
+
+
+### 2.3 Add more builtin functions
+- Support the BitmapAgg function in new optimizer
+  - https://github.com/apache/doris/pull/25508
+- Supports SHA series digest functions
+  - https://github.com/apache/doris/pull/24342 
+- Support the BITMAP datatype in the aggregate functions min_by and max_by

+
+
+## 3 Improvement and optimizations
+
+### 3.1 Performance optimizations
+
+- When the inverted index MATCH WHERE condition with a high filter rate is combined with the common WHERE condition with a low filter rate, the I/O of the index column is greatly reduced. 
+- Optimize the efficiency of random data access after the where filter.
+- Optimizes the performance of the old get_json_xx function on JSON data types by 2~4x.
+- Supports the configuration to reduce the priority of the data read thread, ensuring the CPU resources for real-time writing.
+- Adds `uuid-numeric` function that returns largeint, which is 20 times faster than `uuid` function that returns string.
+- Optimized the performance of case when by 3x.
+- Cut out unnecessary predicate calculations in storage engine execution.
+- Accelerate count performance by pushing down count operator to storage tier.
+- Optimizes the computation performance of the nullable type in and or expressions.
+- Supports rewriting the limit operator before `join` in more scenarios to improve query performance. 
+- Eliminate useless `order by` operators from inline view to improve query performance.
+- Optimizes the accuracy of cardinality estimates and cost models in some cases. 
+- Optimized jdbc catalog predicate pushdown logic.
+- Optimized the read efficiency of the file cache when it's enable for the first time.
+- Optimizes the hive table sql cache policy and uses the partition update time stored in HMS to improve the cache hit ratio. 
+- Optimize mow compaction efficiency.
+- Optimized thread allocation logic for external table query to reduce memory usage 
+- Optimize memory usage for column reader.
+
+
+
+### 3.2 Distributed replica management improvements
+
+Distributed replica management improvements include skipping partition deletion, colocate group deletion, balance failure due to continuous write, and hot and cold seperation table balance.

+
+Dear community, we are pleased to share with you the official release of Apache Doris 2.1.0, now available for download and use as of March 8th. This latest version marks a significant milestone in our journey towards enhancing data analysis capabilities, particularly for handling massive and complex datasets.
+
+With Doris 2.1.0, our primary focus has been on optimizing analysis performance, and the results speak for themselves. We have achieved an impressive performance improvement of over 100% on the TPC-DS 1TB test dataset, making Apache Doris more capable of challenging real-world business scenarios.
+
+- **Quick Download:** [https://doris.apache.org/download/](https://doris.apache.org/download/)
+
+- **GitHub：** [https://github.com/apache/doris/releases](https://github.com/apache/doris/releases)
+
+
+## Performance improvement
+
+### Smarter optimizer
+
+On the basis of V2.0, the query optimizer in Doris V2.1 comes with enhanced statistics-based inference and enumeration framework. We have upgraded the cost model and expanded the optimization rules to serve the needs of more use cases
+
+### Better heuristic optimization
+
+For data analytics at scale or data lake scenarios, Doris V2.1 provides better heuristic query plans. Meanwhile, the RuntimeFilter is more self-adaptive to enable higher performance even without statistical information.
+
+### Parallel adaptive scan
+
+Doris V2.1 has adopted parallel adaptive scan to optimize scan I/O and thus improve query performance. It can avoid the negative impact of unreasonable numbers of buckets. (This feature is currently available on the Duplicate Key model and Merge-on-Write Unique Key model.)
+
+### Local shuffle
+
+We have introduced Local Shuffle to prevent uneven data distribution. Benchmark tests show that Local Shuffle in combination with Parallel Adaptive Scan can guarantee fast query performance in spite of unreasonable bucket number settings upon table creation.
+
+### Faster INSERT INTO SELECT
+
+To further improve the performance of INSERT INTO SELECT, which is a frequent operation in ETL, we have moved forward the MemTable execution-wise to reduce data ingestion overheads. Tests show that this can double the data ingestion speed in most cases compared to V2.0.
+Improved data lake analytics capabilities
+
+## Data lake analytic performance
+
+### TPC-DS Benchmark
+
+According to TPC-DS benchmark tests (1TB) of Doris V2.1 against Trino,
+
+- Without caching, the total execution time of Doris is 56% of that of Trino V435. (717s VS 1296s)
+- Enabling file cache can further increase the overall performance of Doris by 2.2 times. (323s)
+  This is achieved by a series of optimizations in I/O, parquet/ORC file reading, predicate pushdown, caching, and scan task scheduling, etc.
+
+### SQL dialects compatibility
+
+To facilitate migration to Doris and increase its compatibility with other DBMS, we have enabled SQL dialect conversion in V2.1. ([read more](../../lakehouse/sql-dialect)) For example, by set sql_dialect = "trino" in Doris, you can use the Trino SQL dialect as you're used to, without modifying your current business logic, and Doris will execute the corresponding queries for you. Tests in user production environment show that Doris V2.1 is compatible with 99% of Trino SQL.
+
+### Arrow Flight SQL protocol
+
+As a column-oriented database compatible with MySQL 8.0 protocol, Doris V2.1 now supports the Arrow Flight SQL protocol as well so users can have fast access to Doris data via Pandas/Numpy without data serialization and deserialization. For most common data types, the Arrow Flight protocol enables tens of times faster performance than the MySQL protocol.
+
+## Asynchronous materialized view
+
+V2.1 allows creating a materialized view based on multiple tables. This feature currently supports:
+
+- Transparent rewriting: supports transparent rewriting of common operators including Select, Where, Join, Group By, and Aggregation.
+- Auto refresh: supports regular refresh, manual refresh, full refresh, incremental refresh, and partition-based refresh.
+- Materialized view of external tables: supports materialized views based on external data tables such as those on Hive, Hudi, and Iceberg; supported synchronizing data from data lakes into Doris internal tables via materialized views.
+- Direct query on materialized views: Materialized views can be regarded as the result set after ETL. In this sense, materialized views are data tables, so users can conduct queries on them directly.
+
+## Enhanced storage
+
+### Auto-increment column
+
+V2.1 supports auto-increment columns, which can ensure data uniqueness of each row. This lays the foundation for efficient dictionary encoding and query pagination. For example, for precise UV calculation and customer grouping, users often apply the bitmap type in Doris, the process of which entails dictionary encoding. With V2.1, users can first create a dictionary table using the auto-increment column, and then simply load user data into it.
+
+### Auto partition
+
+To further release burden on operation and maintenance, V2.1 allows auto data partitioning. Upon data ingestion, it detects whether a partition exists for the data based on the partitioning column. If not, it automatically creates one and starts data ingestion.
+
+### High-concurrency real-time data ingestion
+
+For data writing, a back pressure mechanism is in place to avoid execessive data versions, so as to reduce resource consumption by data version merging. In addition, V2.1 supports group commit ([read more](../../data-operate/import/import-way/group-commit-manual)), which means to accumulate multiple writing and commit them as one. Benchmark tests on group commit with JDBC ingestion and the Stream Load method present great results.
+
+## Semi-structured data analysis
+
+### A new data type: Variant
+
+V2.1 supports a new data type named Variant. It can accommodate semi-structured data such as JSON as well as compound data types that contain integers, strings, booleans, etcs. Users don't have to pre-define the exact data types for a Variant column in the table schema. The Variant type is handy when processing nested data structures.
+You can include Variant columns and static columns with pre-defined data types in the same table. This will provide you with more flexibility in storage and queries.
+Tests with ClickBench datasets prove that data in Variant columns takes up the same storage space as data in static columns, which is half of that in JSON format. In terms of query performance, the Variant type enables 8 times higher query speed than JSON in hot runs and even more in cold runs.
+
+### IP types
+
+Doris V2.1 provides native support for IPv4 and IPv6. It stores IP data in binary format, which cuts down storage space usage by 60% compared to IP string in plain texts. Along with these IP types, we have added over 20 functions for IP data processing.
+
+### More powerful functions for compound data types
+
+- explode_map: supports exploding rows into columns for the Map data type.
+- Supports the STRUCT data type in the IN predicates
+
+## Workload Management
+
+### Hard isolation of resources
+
+On the basis of the Workload Group mechanism, which imposes a soft limit on the resources that a workload group can use, Doris 2.1 introduces a hard limit on CPU resource consumption for workload groups as a way to ensure higher stability in query performance.
+
+### TopSQL
+
+V2.1 allows users to check the most resource-consuming SQL queries in the runtime. This can be a big help when handling cluster load spike caused by unexpected large queries.
+
+
+## Others
+
+### Decimal 256
+
+For users in the financial sector or high-end manufacturing, V2.1 supports a high-precision data type: Decimal, which supports up to 76 significant digits (an experimental feature, please set enable_decimal256=true.)
+
+### Job scheduler
+
+V2.1 provides a good option for regular task scheduling: Doris Job Scheduler. It can trigger the pre-defined operations on schedule or at fixed intervals. The Doris Job Scheduler is accurate to the second. It provides consistency guarantee for data writing, high efficiency and flexibility, high-performance processing queues, retraceable scheduling records, and high availability of jobs.
+
+### Support Docker fast start to experience the new version
+
+Starting from version 2.1.0, we will provide a separate Docker Image to support the rapid creation of a 1FE, 1BE Docker container to experience the new version of Doris. The container will complete the initialization of FE and BE, BE registration and other steps by default. After creating the container, it can directly access and use the Doris cluster about 1 [minute.In](http://minute.in/) this image version, the default `max_map_count`, `ulimit`, `Swap` and other hard limits are removed. It supports X64 (avx2) machines and ARM machines for deployment. The default open ports are 8000, 8030, 8040, 9030.If you need to experience the Broker component, you can add the environment variable `--env BROKER=true` at startup to start the Broker process synchronously. After startup, it will automatically complete the registration. The Broker name is `test`.
+
+Please note that this version is only suitable for quick experience and functional testing, not for production environment!
+
+## Behavior changed
+
+- The default data model is the Merge-on-Write Unique Key model. enable_unique_key_merge_on_write will be included as a default setting when a table is created in the Unique Key model.
+- As inverted index has proven to be more performant than bitmap index, V2.1 stops supporting bitmap index. Existing bitmap indexes will remain effective but new creation is not allowed. We will remove bitmap index-related code in the future.
+- cpu_resource_limit is no longer supported. It is to put a limit on the number of scanner threads on Doris BE. Since the workload group mechanism also supports such settings, the already configured cpu_resource_limit will be invalid.
+- The default value of enable_segcompaction is true. This means Doris supports compaction of multiple segments in the same rowset.
+- Audit log plug-in
+  - Since V2.1.0, Doris has a built-in audit log plug-in. Users can simply enable or disable it by setting the enable_audit_plugin parameter.
+  - If you have already installed your own audit log plug-in, you can either continue using it after upgrading to Doris V2.1, or uninstall it and use the one in Doris. Please note that the audit log table will be relocated after switching plug-in.
+  - For more details, please see the [docs](../../admin-manual/audit-plugin).

+
+Apache Doris 2.1.3 was officially released on May 21, 2024. This version has updated several improvements, including writing data back to Hive, materialized view, permission management and bug fixes. It further enhances the performance and stability of the system.
+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+
+
+## Feature Enhancements
+
+**1. Support writing back data to hive tables via Hive Catalog**
+
+Starting from version 2.1.3, Apache Doris supports DDL and DML operations on Hive. Users can directly create libraries and tables in Hive through Apache Doris and write data to Hive tables by executing `INSERT INTO` statements. This feature allows users to perform complete data query and write operations on Hive through Apache Doris, further simplifying the integrated lakehouse architecture.
+
+Please refer: [https://doris.apache.org/docs/lakehouse/datalake-building/hive-build/](https://doris.apache.org/docs/lakehouse/datalake-building/hive-build/)
+
+**2. Support building new asynchronous materialized views on top of existing ones**
+
+Users can create new asynchronous materialized views on top of existing ones, directly reusing pre-computed intermediate results for data processing. This simplifies complex aggregation and computation operations, reducing resource consumption and maintenance costs while further accelerating query performance and improving data availability. [#32984](https://github.com/apache/doris/pull/32984)
+
+**3. Support rewriting through nested materialized views**
+
+Materialized View (MV) is a database object used to store query results. Now, Apache Doris supports rewriting through nested materialized views, which helps optimize query performance. [#33362](https://github.com/apache/doris/pull/33362)
+
+**4. New `SHOW VIEWS` statement**
+
+The `SHOW VIEWS` statement can be used to query views in the database, facilitating better management and understanding of view objects in the database. [#32358](https://github.com/apache/doris/pull/32358)
+
+**5. Workload Group supports binding to specific BE nodes**
+
+Workload Group can be bound to specific BE nodes, enabling more refined control over query execution to optimize resource usage and improve performance. [#32874](https://github.com/apache/doris/pull/32874)
+
+**6. Broker Load supports compressed JSON format**
+
+Broker Load now supports importing compressed JSON format data, significantly reducing bandwidth requirements for data transmission and accelerating data import performance. [#30809](https://github.com/apache/doris/pull/30809)
+
+**7. TRUNCATE Function can use columns as scale parameters**
+
+The TRUNCATE function can now accept columns as scale parameters, providing more flexibility when processing numerical data. [#32746](https://github.com/apache/doris/pull/32746)
+
+**8. Add new functions `uuid_to_int` and `int_to_uuid`**
+
+These two functions allow users to convert between UUID and integer, significantly helping in scenarios that require handling UUID data. [#33005](https://github.com/apache/doris/pull/33005)
+
+**9. Add `bypass_workload_group` session variable to bypass query queue**
+
+The `bypass_workload_group` session variable allows certain queries to bypass the Workload Group queue and execute directly, which is useful for handling critical queries that require quick responses. [#33101](https://github.com/apache/doris/pull/33101)
+
+**10. Add strcmp function**
+
+The strcmp function compares two strings and returns their comparison result, simplifying text data processing. [#33272](https://github.com/apache/doris/pull/33272)
+
+**11. Support HLL functions `hll_from_base64` and `hll_to_base64`**
+
+HyperLogLog (HLL) is an algorithm for cardinality estimation. These two functions allow users to decode HLL data from a Base64-encoded string or encode HLL data as a Base64 string, which is very useful for storing and transmitting HLL data. [#32089](https://github.com/apache/doris/pull/32089)
+
+## Optimization and Improvements
+
+**1. Replace SipHash with XXHash to improve shuffle performance**
+
+Both SipHash and XXHash are hashing functions, but XXHash may provide faster hashing speeds and better performance in certain scenarios. This optimization aims to improve performance during data shuffling by adopting XXHash. [#32919](https://github.com/apache/doris/pull/32919)
+
+**2. Asynchronous materialized views support NULL partition columns in OLAP tables**
+
+This enhancement allows asynchronous materialized views to support NULL partition columns in OLAP tables, enhancing data processing flexibility.[#32698](https://github.com/apache/doris/pull/32698)
+
+**3. Limit maximum string length to 1024 when collecting column statistics to control BE memory usage**
+
+Limiting the string length when collecting column statistics prevents excessive data from consuming too much BE memory, helping maintain system stability and performance. [#32470](https://github.com/apache/doris/pull/32470)
+
+**4. Support dynamic deletion of Bitmap cache to improve performance**
+
+Dynamically deleting no longer needed Bitmap Cache can free up memory and improve system performance. [#32991](https://github.com/apache/doris/pull/32991)
+
+**5. Reduce memory usage during ALTER operations**
+
+Reducing memory usage during ALTER operations improves the efficiency of system resource utilization. [#33474](https://github.com/apache/doris/pull/33474)
+
+**6. Support constant folding for complex types**
+
+Supports constant folding for Array/Map/Struct complex types.[#32867](https://github.com/apache/doris/pull/32867)
+
+**7. Add support for Variant type in Aggregate Key Model**
+
+The Variant data type can store multiple data types. This optimization allows aggregation operations on Variant type data, enhancing the flexibility of semi-structured data analysis. [#33493](https://github.com/apache/doris/pull/33493)
+
+**8. Support new inverted index format in CCR** [#33415](https://github.com/apache/doris/pull/33415)
+
+**9. Optimize rewriting performance for nested materialized views** [#34127](https://github.com/apache/doris/pull/34127)
+
+**10. Support decimal256 type in row-based storage format**
+
+Supporting the decimal256 type in row-based storage extends the system's ability to handle high-precision numerical data. [#34887](https://github.com/apache/doris/pull/34887)
+
+## Behavioral Changes
+
+**1. Authorization**
+
+- **Grant_priv permission changes**: `Grant_priv` can no longer be arbitrarily granted. When performing a `GRANT` operation, the user not only needs to have `Grant_priv` but also the permissions to be granted. For example, to grant `SELECT` permission on `table1`, the user needs both `GRANT` permission and `SELECT` permission on `table1`, enhancing security and consistency in permission management. [#32825](https://github.com/apache/doris/pull/32825)
+
+- **Workload group and resource usage_priv**: `Usage_priv` for Workload Group and Resource is no longer global but limited to Resource and Workload Group, making permission granting and usage more specific. [#32907](https://github.com/apache/doris/pull/32907)
+
+- **Authorization for operations**: Operations that were previously unauthorized now have corresponding authorizations for more detailed and comprehensive operational permission control. [#33347](https://github.com/apache/doris/pull/33347)
+
+**2. LOG directory configuration**
+
+The log directory configuration for FE and BE now uniformly uses the `LOG_DIR` environment variable. All other different types of logs will be stored with `LOG_DIR` as the root directory. To maintain compatibility between versions, the previous configuration item `sys_log_dir` can still be used. [#32933](https://github.com/apache/doris/pull/32933)
+
+**3. S3 Table Function (TVF)**
+
+Due to issues with correctly recognizing or processing S3 URLs in certain cases, the parsing logic for object storage paths has been refactored. For file paths in S3 table functions, the `force_parsing_by_standard_uri` parameter needs to be passed to ensure correct parsing. [#33858](https://github.com/apache/doris/pull/33858)
+
+## Upgrade Issues
+
+Since many users use certain keywords as column names or attribute values, the following keywords have been set as non-reserved, allowing users to use them as identifiers. [#34613](https://github.com/apache/doris/pull/34613)
+
+## Bug Fixes
+
+**1. Fix no data error when reading Hive tables on Tencent Cloud COSN**
+
+Resolved the no data error that could occur when reading Hive tables on Tencent Cloud COSN, enhancing compatibility with Tencent Cloud storage services.
+
+**2. Fix incorrect results returned by `milliseconds_diff` function**
+
+Fixed an issue where the `milliseconds_diff` function returned incorrect results in some cases, ensuring the accuracy of time difference calculations. [#32897](https://github.com/apache/doris/pull/32897)
+
+**3. User-defined variables should be rorwarded to the Master node**
+
+Ensured that user-defined variables are correctly passed to the Master node for consistency and correct execution logic across the entire system. [#33013]https://github.com/apache/doris/pull/33013
+
+**4. Fix Schema Change issues when adding complex type columns**
+
+Resolved Schema Change issues that could arise when adding complex type columns, ensuring the correctness of Schema Changes. [#31824](https://github.com/apache/doris/pull/31824)
+
+**5. Fix data loss issue in Routine Load when FE Master node changes**
+
+`Routine Load` is often used to subscribe to Kafka message queues. This fix addresses potential data loss issues that may occur during FE Master node changes. [#33678](https://github.com/apache/doris/pull/33678)
+
+**6. Fix Routine Load failure when Workload Group cannot be found**
+
+Resolved an issue where `Routine Load` would fail if the specified Workload Group could not be found. [#33596](https://github.com/apache/doris/pull/33596)
+
+**7. Support column string64 to avoid join failures when string size overflows unit32**
+
+In some cases, string sizes may exceed the unit32 limit. Supporting the `string64` type ensures correct execution of string JOIN operations. [#33850](https://github.com/apache/doris/pull/33850)
+
+**8. Allow Hadoop users to create Paimon Catalog**
+
+Permitted authorized Hadoop users to create Paimon Catalogs.[#33833](https://github.com/apache/doris/pull/33833)
+
+**9. Fix `function_ipxx_cidr` function issues with constant parameters**
+
+Resolved problems with the `function_ipxx_cidr` function when handling constant parameters, ensuring the correctness of function execution.[#33968](https://github.com/apache/doris/pull/33968)
+
+**10. Fix file download errors when restoring using HDFS**
+
+Resolved "failed to download" errors encountered during data restoration using HDFS, ensuring the accuracy and reliability of data recovery. [#33303](https://github.com/apache/doris/issues/33303)
+
+**11. Fix column permission issues related to hidden columns**
+
+In some cases, permission settings for hidden columns may be incorrect. This fix ensures the correctness and security of column permission settings. [#34849](https://github.com/apache/doris/pull/34849)
+
+**12. Fix issue where Arrow Flight cannot obtain the correct IP in K8s deployments**
+
+This fix resolves an issue where Arrow Flight cannot correctly obtain the IP address in Kubernetes deployment environments.[#34850](https://github.com/apache/doris/pull/34850)

+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+
+## Behavior changes
+
+- Non-existent files will be ignored when querying external tables such as Hive. [#35319](https://github.com/apache/doris/pull/35319)
+
+  The file list is obtained from the meta cache, and it may not be consistent with the actual file list.
+  
+  Ignoring non-existent files helps to avoid query errors.
+
+- By default, creating a Bitmap Index will no longer be automatically changed to an Inverted Index. [#35521](https://github.com/apache/doris/pull/35521)
+
+  This behavior is controlled by the FE configuration item `enable_create_bitmap_index_as_inverted_index`, which defaults to false.
+
+- When starting FE and BE processes using `--console`, all logs will be output to the standard output and differentiated by prefixes indicating the log type. [#35679](https://github.com/apache/doris/pull/35679)
+
+	For more infomation, please see the documentations:
+	
+	- [Log Management - FE Log](../admin-manual/log-management/fe-log.md)
+
+	- [Log Management - BE Log](../admin-manual/log-management/be-log.md)
+
+- If no table comment is provided when creating a table, the default comment will be empty instead of using the table type as the default comment. [#36025](https://github.com/apache/doris/pull/36025)
+
+- The default precision of DECIMALV3 has been adjusted from (9, 0) to (38, 9) to maintain compatibility with the version in which this feature was initially released. [#36316](https://github.com/apache/doris/pull/36316)
+
+## New features
+
+### Query optimizer
+
+- Support FE flame graph tool
+  
+  For more information, see the [documentation](/community/developer-guide/fe-profiler.md)
+  
+- Support `SELECT DISTINCT` to be used with aggregation.
+
+- Support single table query rewrite without `GROUP BY`. This is useful for complex filters or expressions. [#35242](https://github.com/apache/doris/pull/35242).
+
+- The new optimizer fully supports point query functionality [#36205](https://github.com/apache/doris/pull/36205).

+**Apache Doris version 2.1.5 was officially released on July 24, 2024.** In this update, we have optimized various functional experiences for data lakehouse and high concurrency scenarios, functionalities of asynchronous materialized views. Additionaly, we have implemented several improvemnents and bug fixes to enhance the stability. 
+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+## Behavior changes
+
+- The default connection pool size for the JDBC Catalog has been increased from 10 to 30 to prevent connection exhaustion in high-concurrency scenarios. [#37023](https://github.com/apache/doris/pull/37023). 
+
+- The system's reserved memory (low water mark) has been adjusted to `min(6.4GB, MemTotal * 5%)` to mitigate BE OOM issues.
+
+- When processing multiple statements in a single request, only the last statement's result is returned if the `CLIENT_MULTI_STATEMENTS` flag is not set.
+
+- Direct modifications to data in asynchronous materialized views are no longer permitted.[#37129](https://github.com/apache/doris/pull/37129)
+
+- A session variable `use_max_length_of_varchar_in_ctas` has been added to control the behavior of varchar and char type length generation during CTAS (Create Table As Select). The default value is true. When set to false, the derived varchar length is used instead of the maximum length. [#37284](https://github.com/apache/doris/pull/37284)
+
+- Statistics collection now defaults to enabling the functionality of estimating the number of rows in Hive tables based on file size. [#37694](https://github.com/apache/doris/pull/37694)
+
+- Transparent rewrite for asynchronous materialized views is now enabled by default. [#35897](https://github.com/apache/doris/pull/35897)
+
+- Transparent rewrite utilizes partitioned materialized views. If partitions fail, the base tables are unioned with the materialized view to ensure data correctness. [#35897](https://github.com/apache/doris/pull/35897)
+
+## New features
+
+### Lakehouse
+
+- The session variable `read_csv_empty_line_as_null` can be used to control whether empty lines are ignored when reading CSV format files. [#37153](https://github.com/apache/doris/pull/37153) 
+
+  By default, empty lines are ignored. When set to true, empty lines will be read as rows where all columns are null.
+
+- Compatibility with Presto's complex type output format can be enabled by setting `serde_dialect="presto"`. [#37253](https://github.com/apache/doris/pull/37253)
+
+### Multi-Table Materialized View
+
+- Supports non-deterministic functions in materialized view building. [#37651](https://github.com/apache/doris/pull/37651)
+
+- Atomically replaces definitions of asynchronous materialized views. [#37147](https://github.com/apache/doris/pull/37147)
+
+- Views creation statements can be viewed via `SHOW CREATE MATERIALIZED VIEW`. [#37125](https://github.com/apache/doris/pull/37125)
+
+- Transparent rewrites for multi-dimensional aggregation and non-aggregate queries. [#37436](https://github.com/apache/doris/pull/37436) [#37497](https://github.com/apache/doris/pull/37497)
+
+- Supports DISTINCT aggregations with key columns and partitioning for roll-ups. [#37651](https://github.com/apache/doris/pull/37651)  
+
+- Support for partitioning materialized views to roll up partitions using `date_trunc` [#31812](https://github.com/apache/doris/pull/31812) [#35562](https://github.com/apache/doris/pull/35562)
+
+- Partitioned table-valued functions (TVFs) are supported. [#36479](https://github.com/apache/doris/pull/36479)
+
+### Semi-Structured Data Management
+
+- Tables using the VARIANT type now support partial column updates. [#34925](https://github.com/apache/doris/pull/34925)
+
+- PreparedStatement support is now enabled by default. [#36581](https://github.com/apache/doris/pull/36581)
+
+- The VARIANT type can be exported to CSV format. [#37857](https://github.com/apache/doris/pull/37857)
+
+- `explode_json_object` function transposes JSON Object rows into columns. [#36887](https://github.com/apache/doris/pull/36887)
+
+- The ES Catalog now maps ES NESTED or OBJECT types to the Doris JSON type.[#37101](https://github.com/apache/doris/pull/37101)
+
+- By default, support_phrase is enabled for inverted indexes with specified analyzers to improve the performance of match_phrase series queries. [#37949](https://github.com/apache/doris/pull/37949)
+
+### Query Optimizer
+
+- Support for explaining `DELETE FROM` statements. [#37100](https://github.com/apache/doris/pull/37100)
+
+- Support for hint form of constant expression parameters [#37988](https://github.com/apache/doris/pull/37988)
+
+### Memory Management
+
+- Added an HTTP API to clear the cache. [#36599](https://github.com/apache/doris/pull/36599)
+
+### Permissions
+
+- Support for authorization of resources within Table-Valued Functions (TVFs) [#37132](https://github.com/apache/doris/pull/37132)

+## Improvements
+
+### Lakehouse
+
+- Upgraded Paimon to version 0.8.1

+
+- Improved default connection logic for SQLServer JDBC Catalog. [#36971](https://github.com/apache/doris/pull/36971)
+
+  By default, the connection encryption settings are not intervened. Only when `force_sqlserver_jdbc_encrypt_false` is set to true, encrypt=false is forcibly added to the JDBC URL to reduce authentication errors. This allows for more flexible control over encryption behavior, enabling it to be turned on or off as needed.
+
+- Added serde properties to the show create table statements for Hive tables. [#37096](https://github.com/apache/doris/pull/37096)

+
+- Fixed an issue where inner-outer table join queries could lead to FE timeouts in some cases [#37757](https://github.com/apache/doris/pull/37757)
+
+- Fixed an issue with FE metadata replay errors during upgrades from older versions to newer versions when the Hive metastore event listener is enabled. [#37757](https://github.com/apache/doris/pull/37757)

+
+- Improve planning speed for transparent rewrites. [#37935](https://github.com/apache/doris/pull/37935)
+
+- When calculating the availability of asynchronous materialized views, the current refresh status is no longer taken into account. [#36617](https://github.com/apache/doris/pull/36617)
+
+### Semi-Structured Data Management
+
+- Optimize DESC performance for viewing VARIANT sub-columns through sampling. [#37217](https://github.com/apache/doris/pull/37217)
+
+- Support for special JSON data with empty keys in the JSON type. [#36762](https://github.com/apache/doris/pull/36762)

+## Upgrade suggestions
+
+When upgrading Doris, please follow the principle of not skipping two minor versions and upgrade sequentially.
+
+For example, if you are upgrading from version 0.15.x to 2.0.x, it is recommended to first upgrade to the latest version of 1.1, then upgrade to the latest version of 1.2, and finally upgrade to the latest version of 2.0.
+
+For more upgrade information, see the documentation: [Cluster Upgrade](../../admin-manual/cluster-management/upgrade)
