Replication mode
The following replication modes are available:
信息注释When replicating from SaaS application sources, the Full load replication mode is enabled by default and cannot be disabled.
- 满负载：将选定源表中的数据加载到目标平台，并在必要时创建目标表。当任务启动时，满负载会自动发生，但如果需要，也可以手动执行。
- 应用更改：使目标表持续更新对源表所做的任何更改。
-
存储更改：将对源表的更改存储在“更改表”中（每个源表一个）。
有关详细信息，请参阅存储更改。
If you select Store changes or Apply changes and your source data contains tables that do not support CDC, or views, two data pipelines will be created. One pipeline for tables that support CDC, and another pipeline for all other tables and views that support Full load only.
信息注释ALTER TABLE DDL operations are not currently supported. Other DDL operations such as DROP TABLE and TRUNCATE TABLE are supported.
Apply changes mode
Changes are applied to the target tables using one of the following methods:
- 批量优化：这是默认设置。选择此选项后，将分批应用更改。进行预处理操作，以最有效的方式将事务分组为批。
- 事务性：选择此选项可以按照提交的顺序单独应用每个事务。在这种情况下，可以确保所有表都具有严格的引用完整性。
