Subject [jira] [Commented] (HBASE-7883) Update memstore size when removing the entries in append operation
Date Wed, 20 Feb 2013 14:31:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13582206#comment-13582206

nkeywal commented on HBASE-7883:
--------------------------------

Nit: there is no need to initialize delta to zero. Personally, I think it deserves a test
as well, it's a critical part and it should fit into TestMemStore. So let say I would be +0.9
here.
@JM: it means less flushes & compactions (if you meet the conditions for this patch, obviously).
