Check Details

Check objective
Verify whether the number of objects to be synchronized is within the limit scope of the system.
Check content
Check whether the number of tables to be synchronized exceeds the system limit (up to 6,000 tables per task).
Check whether the number of databases to be synchronized is within the allowed scope (up to 100 databases per task).
Potential issue
The number of objects to be synchronized exceeds the system limit.

Fixing Method

It is recommended to split large synchronization tasks into multiple smaller tasks.
Group tables by business module or priority for synchronization.
Synchronize core business tables first; non-core tables can be synchronized subsequently.
