Subject [jira] [Commented] (HBASE-14921) Memory optimizations
Date Fri, 01 Apr 2016 17:19:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14921?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15222013#comment-15222013

ramkrishna.s.vasudevan commented on HBASE-14921:
------------------------------------------------

As per the internal discussion that we were having we were not sure if the 3 ints that we
need for indexing also needs to be fetch from MSLAB and that will also be offheap. Any way
we can experiment to see the pros and cons.
