I am not sure if you or someone else is planning to pick it as it seems to be related to the raft protocol KIP.. Let me know plz. > Explore performance impact of leader fsync deferral > --------------------------------------------------- > > Key: KAFKA-10526 > URL: https://issues.apache.org/jira/browse/KAFKA-10526 > Project: Kafka > Issue Type: Sub-task > Reporter: Jason Gustafson > Priority: Major > > In order to commit a write, a majority of nodes must call fsync in order to > ensure the data has been written to disk. An interesting optimization option > to consider is letting the leader defer fsync until the high watermark is > ready to be advanced. This potentially allows us to reduce the number of > flushes on the leader. -- This message was sent by Atlassian Jira (v8.3.4#803005)
