------------------------------------------------------------
After the Follower role's Region on the TiKV node successfully persists the Raft Log to its own RocksDB Raft instance, it will return a success message to the Leader role's Region on the TiKV node.
 
Once the majority of the Follower replicas have acknowledged the message, the write process is committed, ensuring that it is fully persisted on the Raft layer and will not be lost.
