Subject [jira] [Commented] (CASSANDRA-11514) trunk compaction performance regression
Date Thu, 07 Apr 2016 15:41:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11514?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15230421#comment-15230421
] 

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

[trunk_3.5_3.0-compaction_LCS|http://cstar.datastax.com/tests/artifacts/7b642270-fccc-11e5-bf65-0256e416528f/graph]
shows that both trunk and 3.5 seem to have the same issue. 'op rate' text and 'Total operations'
graph seem to agree.
[trunk_3.5_3.0-compaction_DTCS|http://cstar.datastax.com/tests/artifacts/2aace7d6-fccc-11e5-bf65-0256e416528f/graph]
is less conclusive.

I'm going to run both for a longer period and write more data to see if I can get a little
more definitive answer.

> 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.
