Subject [jira] [Commented] (HBASE-10374) add jemalloc into the choice of memstore allocation
Date Fri, 17 Jan 2014 21:15:30 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13875265#comment-13875265

Nick Dimiduk commented on HBASE-10374:
--------------------------------------

Premature submit. As I was a saying.

I don't have conclusive reasons to pursue Netty ByteBufs vs nio ByteBuffers. The compositional
structure Netty provides is really nice, if we can use it, but I think it could be implemented
on top of stock ByteBuffers as well.

Netty used jemalloc to gain benefits from GC.
