---------------------------------------

             Summary: Raft leader should flush accumulated writes after a min 
size is reached
                 Key: KAFKA-10652
                 URL: https://issues.apache.org/jira/browse/KAFKA-10652
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Jason Gustafson


In KAFKA-10601, we implemented linger semantics similar to the producer to let 
the leader accumulate a batch of writes before fsyncing them to disk. Currently 
the fsync is only based on the linger time, but it would be helpful to make it 
size-based as well. In other words, if we accumulate a configurable N bytes, 
then we should not wait for linger expiration and should just fsync immediately.
