canal编辑如下,B数据本身没有数据库和表,难道otter 不会主动定位,未免太不智能了。单表测试没有问题。

Research direction

Start by reproducing the reported A-to-B synchronization with the zcm_bak database present on A but absent on B, using the canal configuration and database/table management shown in the report. The payload names no source file or test entry point, so first identify where this synchronization error is raised. Done means the missing database and table case is handled as intended, with a regression test for the reported setup.
