Dinesh Joshi updated CASSANDRA-15657: ------------------------------------- Reviewers: Dinesh Joshi, T Jake Luciani (was: Dinesh Joshi) > Improve zero-copy-streaming containment check by using file sections > -------------------------------------------------------------------- > > Key: CASSANDRA-15657 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15657 > Project: Cassandra > Issue Type: Improvement > Components: Legacy/Streaming and Messaging > Reporter: ZhaoYang > Assignee: ZhaoYang > Priority: Normal > Fix For: 4.0 > > > Currently zero copy streaming is only enabled for leveled-compaction strategy > and it checks if all keys in the sstables are included in the transferred > ranges. > This is very inefficient. The containment check can be improved by checking > if transferred sections (the transferred file positions) cover entire sstable. > I also enabled ZCS for all compaction strategies since the new containment > check is very fast.. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
