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.
