Subject [jira] [Commented] (HBASE-14098) Allow dropping caches behind compactions
Date Thu, 30 Jul 2015 17:27:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14098?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14647988#comment-14647988

Lars Hofhansl commented on HBASE-14098:
---------------------------------------

Was just going to +1... Missed the private readers bit.
I added the private.readers features and order to decouple compactions readers from "operational"
readers (user scans, gets, etc).
Defensively I defaulted this to false, but I think we can safely enable that always... But
if we wanted to stay defensively we could default to the value of "drop caches behind compactions".

Actually, in either case +1 from me.
