Subject [jira] [Commented] (CASSANDRA-11514) trunk compaction performance regression
Date Thu, 07 Apr 2016 19:49:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11514?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15230918#comment-15230918
] 

Michael Shuler commented on CASSANDRA-11514:
--------------------------------------------

Larger run on DTCS [trunk_3.5_3.0-compaction_DTCS|http://cstar.datastax.com/tests/artifacts/c9dd18fc-fcd7-11e5-8f8b-0256e416528f/graph]
seems to support that trunk and 3.5 both have this commit. The differences seem pretty small,
so it could be difficult to determine a difference between 2 commits.

> It appears that a commit between Mar 29-30 has resulted in a drop in compaction performance.
I attempted to get a log list of commits to post here, but
> {noformat}
> git log trunk@{2016-03-29}..trunk@{2016-03-31}
> {noformat}
> appears to be incomplete, since reading through {{git log}} I see netty and och were
upgraded during this time period.
