+### schema_save_mode[Enum]
+
+Before starting the synchronization task, choose different processing options for the existing table schema.  
+Option descriptions:  
+`RECREATE_SCHEMA`: Create the table if it does not exist; drop and recreate the table when saving.  
+`CREATE_SCHEMA_WHEN_NOT_EXIST`: Create the table if it does not exist; skip if the table already exists.  
+`ERROR_WHEN_SCHEMA_NOT_EXIST`: Throw an error if the table does not exist.  
+`IGNORE`: Ignore the processing of the table.
+
+### data_save_mode[Enum]
+
+Before starting the synchronization task, choose different processing options for the existing data on the target side.  
+Option descriptions:  
+`DROP_DATA`: Retain the database schema but delete the data.  
+`APPEND_DATA`: Retain the database schema and the data.  
+`CUSTOM_PROCESSING`: Custom user-defined processing.  
+`ERROR_WHEN_DATA_EXISTS`: Throw an error if data exists.
+
+### save_mode_create_template
+
+Automatically create Doris tables using templates.  
+The table creation statements will be generated based on the upstream data types and schema. The default template can be modified as needed.
+
+Default template:
+```sql
+CREATE TABLE IF NOT EXISTS `${database}`.`${table}` (
+    ${rowtype_primary_key},
+    ${rowtype_fields}
+) ENGINE = MergeTree()
+ORDER BY (${rowtype_primary_key})
+PRIMARY KEY (${rowtype_primary_key})
+SETTINGS
+    index_granularity = 8192;
+```
+
+If custom fields are added to the template, for example, adding an `id` field:
+
+```sql
+CREATE TABLE IF NOT EXISTS `${database}`.`${table}` (
+    id,
+    ${rowtype_fields}
+) ENGINE = MergeTree()
+    ORDER BY (${rowtype_primary_key})
+    PRIMARY KEY (${rowtype_primary_key})
+    SETTINGS
+    index_granularity = 8192;
+```
+
+The connector will automatically retrieve the corresponding types from the upstream source and fill in the template, removing the `id` field from the `rowtype_fields`. This method can be used to modify custom field types and attributes.
+
+The following placeholders can be used:
+
+- `database`: Retrieves the database from the upstream schema.
+- `table_name`: Retrieves the table name from the upstream schema.
+- `rowtype_fields`: Retrieves all fields from the upstream schema and automatically maps them to Doris field descriptions.
+- `rowtype_primary_key`: Retrieves the primary key from the upstream schema (this may be a list).
+- `rowtype_unique_key`: Retrieves the unique key from the upstream schema (this may be a list).

+选项介绍：  
+`RECREATE_SCHEMA` ：表不存在时创建，表保存时删除并重建。
+`CREATE_SCHEMA_WHEN_NOT_EXIST` ：表不存在时会创建，表存在时跳过。  
+`ERROR_WHEN_SCHEMA_NOT_EXIST` ：表不存在时会报错。  
+`IGNORE` ：忽略对表的处理。
+
+### data_save_mode[Enum]
+
+在开启同步任务之前，针对目标端已有的数据选择不同的处理方案。
+选项介绍：  
+`DROP_DATA`： 保留数据库结构并删除数据。  
+`APPEND_DATA`：保留数据库结构，保留数据。  
+`CUSTOM_PROCESSING`：用户自定义处理。  
+`ERROR_WHEN_DATA_EXISTS`：有数据时报错。
+
+### save_mode_create_template
+
+使用模板自动创建Doris表，
+会根据上游数据类型和schema类型创建相应的建表语句，
+默认模板可以根据情况进行修改。
+
+默认模板：
+```sql
+CREATE TABLE IF NOT EXISTS  `${database}`.`${table}` (
+    ${rowtype_primary_key},
+    ${rowtype_fields}
+) ENGINE = MergeTree()
+ORDER BY (${rowtype_primary_key})
+PRIMARY KEY (${rowtype_primary_key})
+SETTINGS
+    index_granularity = 8192;
+```
+
+如果模板中填写了自定义字段，例如添加 id 字段
+
+```sql
+CREATE TABLE IF NOT EXISTS  `${database}`.`${table}` (
+    id,
+    ${rowtype_fields}
+) ENGINE = MergeTree()
+    ORDER BY (${rowtype_primary_key})
+    PRIMARY KEY (${rowtype_primary_key})
+    SETTINGS
+    index_granularity = 8192;
+```
+
+连接器会自动从上游获取对应类型完成填充，
+并从“rowtype_fields”中删除 id 字段。 该方法可用于自定义字段类型和属性的修改。
+
+可以使用以下占位符：
+
+- database：用于获取上游schema中的数据库。
+- table_name：用于获取上游schema中的表名。
+- rowtype_fields：用于获取上游schema中的所有字段，自动映射到Doris的字段描述。
+- rowtype_primary_key：用于获取上游模式中的主键（可能是列表）。
+- rowtype_unique_key：用于获取上游模式中的唯一键（可能是列表）。
