Subject [jira] [Commented] (CASSANDRA-5595) Add counters to TRACE for how much CASSANDRA-5514 helped a query
Date Tue, 28 May 2013 15:32:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5595?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13668369#comment-13668369
] 

Jonathan Ellis commented on CASSANDRA-5595:
-------------------------------------------

We actually don't want to use varargs in Tracing since it forces array allocation even if
tracing is off.
