Subject [jira] [Commented] (HBASE-12202) Support DirectByteBuffer usage in HFileBlock
Date Wed, 08 Oct 2014 17:31:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14163826#comment-14163826

ramkrishna.s.vasudevan commented on HBASE-12202:

We discussed about this.  
Already we raised a JIRA to make BRs to be used in HFileBlock. But not sure if that is needed
now.  If so we need to pursue that also. Should we try for BR?
Also the thought is that we may not convert entire read path starting from DFS client passed
byte [] to be converted to ByteBuffer at the first stage. Only when the block moves to L2
cache from there start serving the reads from Offheap byte buffer. What do you think? Do you
feel we can address from the DFSClient API itself?
