> Currently both write and readonly calls in Ratis use RaftClient.send which enqueues the
the request to the raft log and is processed later when the log entry is consumed.
> Readonly call can be optimized by using RaftClient.sendReadOnly which will directly query
the RaftServer for a particular request.
> This jira will be used to discuss this issue.
