> There are two scenarios which can lead to such a situation.
> # Raft leader accepts an entry and puts it in its retry cache. But it fails
> or changes before it can append the entries to its follower. In such a case
> the entry would remain in its retry cache. If this leader is chosen again by
> the ring, any subsequent request by the raft client would wait indefinitely
> for the future in retry cache entry to complete.
> # The leader receives the request but dies before replying to it.
> Below are the log entries corresponding to first scenario.
