Subject [jira] Updated: (CASSANDRA-580) vector clock support
Date Thu, 06 May 2010 09:36:56 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-580?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sylvain Lebresne updated CASSANDRA-580:
---------------------------------------

    Attachment: 580-1-Add-ColumnType-as-enum.patch

Attached patch is the first part of the wip patch (ColumnType as enum) rebased 
against trunk. It ships the addition of the ColumnType in superColumns which is 
not strictly needed per se but make sense here I believe (note that this patch depends
on CASSANDRA-1054).

Since I did not wrote this, I merely rebased it, I'll +1 it (just this first part of course)
at 
the same time.
