“TiDB is a distributed SQL database that features horizontal scalability, strong consistency, and high availability. It is compatible with the MySQL protocol and can be used as a drop-in replacement for MySQL. TiDB’s architecture separates storage and computing, allowing it to handle large-scale data and high concurrency scenarios efficiently.”

First, cancel the TiFlash synchronization configuration for this table and see if the issue persists.

If not, try reconfiguring the synchronization.

Tried it, but it didn’t work. We are planning to scale in and then scale out.

Alright, that’s one way to do it.

Just now, V6.5.1 has been released.

Is it necessary to wait for a while before the official binary package of the community edition can be downloaded? It seems that it is not available yet.
