Subject [jira] [Commented] (HBASE-16417) In-Memory MemStore Policy for Flattening and Compactions
Date Tue, 28 Feb 2017 16:51:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15888424#comment-15888424

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

What is the size of each KV? Are you doing YCSB or PE?
bq.Could it be due to double logging of the same information?
I don't think so. But not sure. I think depends on your cell size though value is 100B only.
bq.Here the sizes of the files vary, NONE/BASIC write roughly 850 files, EAGER roughly 480.
Something to check. Async mode as per our experiments were bit slower and had some bugs that
[~Apache9] fixed. But I don't think we had any data loss there. Can check once.
