[jira] [Commented] (RATIS-710) GC pauses in leader should not
penalize appendRequest response processing
[ https://issues.apache.org/jira/browse/RATIS-710?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16963043#comment-16963043 ]
Lokesh Jain commented on RATIS-710:
-----------------------------------
[~szetszwo] This might not require a fix after RATIS-457. On timeout leader only removes the append entry request from pendingRequests map.

> In ozone perf testing, it was observed that once leader goes through gc pause cycle and wakes up, it just times out all append requests , but the follower seems to be processing the append requests fine. It goes in a loop and ends up failing the watch requests on the leader.
