Subject [jira] [Commented] (CASSANDRA-7486) Migrate to G1GC by default
Date Tue, 22 Sep 2015 15:28:07 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14902802#comment-14902802

Ryan McGuire commented on CASSANDRA-7486:
-----------------------------------------

The code was deployed, but the git fetch didn't work. We'll fix that. I manually fetched from
my repo, so it'll work with that stress revision for now.

> May want to default 2.1 to G1.
> 2.1 is a different animal from 2.0 after moving most of memtables off heap.  Suspect
this will help G1 even more than CMS.  (NB this is off by default but needs to be part of
the test.)
