[jira] Commented: (CASSANDRA-2070) replace ExpiringMap with google collections MapMaker

    [ https://issues.apache.org/jira/browse/CASSANDRA-2070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12995848#comment-12995848 ] 

Jonathan Ellis commented on CASSANDRA-2070:
-------------------------------------------

I didn't realize that the guava API doesn't give us access to the Entry age.  Double-wrapping with another Entry is not worth it (this is a performance-critical section).  I opened http://code.google.com/p/guava-libraries/issues/detail?id=550 as an enhancement request; closing this as WontFix until/unless that gets addressed.
