Mukul Kumar Singh commented on RATIS-341:
-----------------------------------------
Thanks for the review [~szetszwo]. The changes in leader state are needed for a
slow follower.
For a slow node which is catching up, the commit index send along with the
append request can be beyond the log indexes sent to the follower.
> Raft log index on the follower should be applied to state machine only after
> writing the log
