Subject [jira] [Commented] (CASSANDRA-13090) Coalescing strategy sleeps too much
Date Mon, 20 Feb 2017 20:19:44 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15875023#comment-15875023

Ariel Weisberg commented on CASSANDRA-13090:
--------------------------------------------

It's a mistake. I'll need to update changes.txt. Originally I was going to disable it, but
after discussion it seems like we didn't want to change out of the box performance in older
releases.

> With the current code maybeSleep is called even if we managed to take maxItems out of
the backlog. In this case we should really avoid sleeping because it means that backlog is
building up.
> I'll send a patch shortly.
