Subject [jira] Commented: (CASSANDRA-580) vector clock support
Date Wed, 14 Apr 2010 12:52:57 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12856871#action_12856871
] 

Jonathan Ellis commented on CASSANDRA-580:
------------------------------------------

If there is any "prep" refactoring in here it should be pulled out to a separate patch.  It's
impossible to say, looking at at 300k patch.

Adding system tests should make most of the TODO: TESTs go away, right?
