Subject [jira] [Commented] (HBASE-4956) Control direct memory buffer consumption by HBaseClient
Date Thu, 03 May 2012 21:52:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13267849#comment-13267849

Lars Hofhansl commented on HBASE-4956:
--------------------------------------

Yeah, we should quantify this. 8k seems like a very reasonable chunk size, though (probably
anything between 1k and 64k would be OK :) ).

@Bob: Any chance you can whip up a quick performance test for this?

, standard hbase client inadvertently consumes large amount of direct memory.
> We should consider using netty for NIO-related tasks.
