Subject [jira] Commented: (CASSANDRA-1481) PropertyFileEndPointSnitch synchronization is a bottleneck
Date Tue, 14 Sep 2010 21:36:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12909464#action_12909464

Brandon Williams commented on CASSANDRA-1481:
---------------------------------------------

+1, though for consistency, the brace on newline in displayConfiguration could be inlined.
 But PFEPS is already a mess in that regard, so no big deal.
