runzhiwang updated RATIS-836:
-----------------------------
Description:
*What's the problem ?*
Before send normal request, ratis client will send an [empty
request|https://github.com/apache/incubator-ratis/blob/master/ratis-client/src/main/java/org/apache/ratis/client/impl/OrderedAsync.java#L235]
to server to check the leader state, which cost about 5 millseconds.
*How to improve ?*
I think it can be improved by send normal request directly to server, if the
server was not leader, response client with the NotLeaderException and client
retry the request. [~msingh] What do you think ? If you agree with it, I will
submit an PR.
