Subject [jira] [Commented] (CASSANDRA-5159) Expose droppable tombstone ratio stats over JMX
Date Sun, 22 Dec 2013 15:56:51 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13855198#comment-13855198

Marcus Eriksson commented on CASSANDRA-5159:
--------------------------------------------

did you wait gc_grace time after doing the deletes? tombstones are not droppable until after
that time.

> Could be nice to be able to jmx-monitor the tombstone histogram collected during compactions
to see how many gc-able tombstones there are left due to the row existing in other sstables
