    In scenarios where multiple sync tasks need to be configured, such as many-to-one sync and active-active sync, the same table object cannot receive DDL sync from multiple IDCs; otherwise, such DDL statements may conflict with each other in the target database, causing errors.

    For example, as shown below, databases A and C have tables with the same name to be synced to database B. Then, you can select DDL in only one task between tasks 1 and 4.


    Modify the sync task configuration. In Set sync options and objects > Data Sync Option > SQL Type, modify the DDL parameter configuration to avoid the situation where the same table object receives DDL sync from multiple IDCs.
