Subject [jira] [Commented] (HBASE-16417) In-Memory MemStore Policy for Flattening and Compactions
Date Thu, 24 Nov 2016 10:12:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15692865#comment-15692865

ramkrishna.s.vasudevan commented on HBASE-16417:
------------------------------------------------

In my opinion #2 has an impact due to xmx also. If you have 30G then you could actually have
a better GC pattern with more threads and more flushes and GCs. With 16G your heap is overloaded
when you have flushes/compactions happening frequently as a major garbage generator are from
those two operations.
