Ivan Andika updated RATIS-2497:
-------------------------------
Description:
Currently the dummy request is a WATCH(0) which will trigger client leader
failover. In a follower read client scenario, this might cause client to always
failover to the leader which reduces the follower read effectiveness.
We can try to implement a new noop request (some kind of ping request) which
simply returns a successful response.
