Subject [jira] [Commented] (HBASE-16417) In-Memory MemStore Policy for Flattening and Compactions
Date Fri, 11 Nov 2016 05:13:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15656167#comment-15656167

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

In the figure that represent Write only work load , you see more GC when there is MSLAB (with
no compaction)? 
How many region in your PE tool and YCSB?  You have only 16G memory and 0.42 of it is 6.72
G for blocking memstore. So number of regions may be important here to check other wise you
can easily overload a region with lot of blocking updates. Just saying.
