Gasol Wu commented on CASSANDRA-293:
------------------------------------

the RowMutation.delete() that  have some condition like below, so i can't batch remove columns,
does there have any concern about it?

if (modifications_.containsKey(cfName))
{
       throw new IllegalArgumentException("ColumnFamily " + cfName + " is already being modified");
}

> For cleaning up old data on a rotating basis, a removal operation which operates on key
ranges would be very handy, currently we have to remove every single column individually.
