[jira] [Created] (RATIS-727) Garbage collection due to same request retries on a follower

Lokesh Jain created RATIS-727:
---------------------------------

             Summary: Garbage collection due to same request retries on a follower
                 Key: RATIS-727
                 URL: https://issues.apache.org/jira/browse/RATIS-727
             Project: Ratis
          Issue Type: Bug
          Components: client
            Reporter: Lokesh Jain


In a heap dump it could be seen that a client request retries on the same follower multiple times and every time the request is rejected with a NotLeaderException. In case of Ozone it is a WriteChunk request which leads to garbage collection of 16MB for every request. In the heap dump a client request retries multiple times leading to garbage collection of ~100MB.
