Subject [jira] [Commented] (HBASE-11702) Better introspection of long running compactions
Date Wed, 13 Aug 2014 17:26:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14095753#comment-14095753

Andrew Purtell commented on HBASE-11702:
----------------------------------------

bq. Number of bytes still important, right? (I'd say more important than Cell count) For compaction
we already get the length of each KV, can add to Flushes as well. Followup jira? If you're
tired of me asking I can add that

I'm not sure whether number of bytes or number of cells would be the more useful metric but
why not have both. No problem. Back with a new patch shortly.
