There is always an unresolved sharding group in unresolvedGroups. This DDL has already been skipped and is no longer affecting anything, but the syncerBinlog data is not updating. The actual test data is being synchronized.

Has it never been updated, or was it updated after a while?

It’s been a long time since the last update. I checked it this morning and it’s back to normal.

That should just be the checkpoint not being flushed to disk, no big deal.

Well, it’s just that this process is a bit long, which makes people feel uneasy, and we don’t know what causes this problem.
