Yes, this engine is not compatible with TiFlash.
partitioned-raft-kv is an experimental feature and has not been officially GA, right?

Oh, there’s such a situation? I was planning to enable it too, but luckily I didn’t. Adjusting parameters in TiDB is risky; I’ve encountered bugs caused by parameter changes twice already.

Partitioned Raft KV | PingCAP Documentation Center does not support TiFlash

It can run in actual tests, but it is not officially supported yet. You can research partitionkv on your own and wait until it is GA before using it.

It’s okay, this only takes effect when initializing the cluster. After initialization, any modifications will not take effect.

This setting is not compatible with TiFlash.

It can be synchronized and is usable in most cases. However, there are some known compatibility issues that have not yet been resolved.

Most of them can be used normally.
