runzhiwang updated RATIS-836:
-----------------------------
Description: 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. I think
it can be improved by send normal request directly to server, if the server was
not leader, response client with the NotLeaderException. (was: 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 mill-seconds. I think
it can be improved by send normal request directly to server, if the server was
not leader, response client with the NotLeaderException. )
