Release Note 2.0.3

[xiaokang]

Previous Release Note 2.0.2

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.
  • [Fix](Serde) Fix content displayed by complex types in MySQL Client #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.
  • [improvement](auth) support show view priv #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.

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.

• 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.

[bingwill]

我们在使用部分列更新功能的时候遇到这样一个问题（使用的是2.02版本）：
1、开启了部分列更新的功能，然后发现批量insert 多values 写入数据时会出错，单条写入没有问题。
2、数据删除后，再写入会不成功，然后把主键的值改改就可以写入了。
