Subject [jira] [Commented] (CASSANDRA-3269) accumulated 100GB of commit logs
Date Thu, 29 Sep 2011 18:13:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3269?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13117493#comment-13117493

Yang Yang commented on CASSANDRA-3269:
--------------------------------------

I don't think so, I have set the memtable_total_space to be very high
due to my larger memory available, and rely on the
commit_log_total_size to trigger flushing  (also I changed the
getLiveSize() ... as I said in the other JIRA I commented , since my
traffic contains a large portion of counter adds). so essentially the
only trigger for flushing should come from commit_log_total_size
threshold,  but I don't see these flushing requests coming out, it's
not that the flushing started and can't finish.


I'm still running it, let me set it to a smaller threshold and
hopefully get to the point soon.
