I have two questions:

  1. How to identify whether the data in TiFlash’s apply snapshot is split from other nodes or is completely new and has never been stored on other nodes?
  2. Under what circumstances does TiFlash data synchronization follow the ApplySnapshot and handleWriteRaftCmd branches?

github issue and tidb internal community might be better places for discussion.
