Subject [jira] Updated: (CASSANDRA-531) truncate support
Date Fri, 06 Nov 2009 17:04:32 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-531?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis updated CASSANDRA-531:
-------------------------------------

    Description: 
Sometimes you want to delete an entire columnfamily.  If there is a lot of data, it's much
faster to just insert something to the commitlog saying "truncated," and drop the memtable
and data files.

Probably should require this to block for all replicas to ack to avoid unpleasant surprises.
 Or make it local-only and have ops manage making sure it gets to all replicas.
