Subject [jira] [Commented] (CASSANDRA-5519) Reduce index summary memory use for cold sstables
Date Thu, 21 Nov 2013 23:37:37 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13829475#comment-13829475
] 

Jonathan Ellis commented on CASSANDRA-5519:
-------------------------------------------

Hmm.  I see two uses of isReplaced:

# releaseReference, which can be reverted back to trunk form since isReplaced == !isCompacted
# close, which is only called by snapshot repair (and releaseReference) which will never do
any index summary replacements
