Subject [jira] [Commented] (HBASE-16417) In-Memory MemStore Policy for Flattening and Compactions
Date Thu, 18 Aug 2016 09:00:36 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426121#comment-15426121

Anastasia Braginsky commented on HBASE-16417:
---------------------------------------------

Answering [~anoop.hbase] and [~ram_krish] from HBASE-14921

In HBASE-14921, we run YCSB small just to ensure the correctness. In this JIRA we’ll resolve
the performance issues.

So in YCSB we did: 10 cols, 20 threads, only writes.  1G data, but very small heap - 1G, so
in the sense of garbage collection we should be the same. The GC is Concurrent Mark &
Sweep and we do not see GC pauses. We run with duplications and without. I will give a run
now with more data.
