-------------------------------------------------------------
At T3 time, TiFlash, in order to satisfy the client's read, went to TiKV to confirm the current sequence number (Raft Log Index) of the Raft Log, and obtained the Raft Log Index value of key = 1 as 125, and the Raft Log Index value of key = 999 as 31.
