Riguz Lee commented on RATIS-1622:
----------------------------------
{quote}Right, shouldSendAppendEntries() will keep returning true. How about we
enforce a min wait time as below?
{quote}
It still has the issue, because shouldSendAppendEntries() is true when a
follower is offline. My idea is that we can avoid sending to those dead
followers too frequently by checking the lastGrpcResponseTime of a follower.
I've opened [https://github.com/apache/ratis/pull/680] and please help to
review that.
BTW, I cannot pass some tests, and it takes 1 hour to run all the tests! I
cannot make it work in windows, but mvn verify works in WSL.
