> 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.
