-------------------------------------------

Oh, I think I understand.  You're thinking along the lines of CASSANDRA-2524 ?

> Right now cleanup is optimized to simply delete sstables that *only* contain data that
doesn't belong on the node, for all other sstables though, it will read them, check each row,
and write out new sstables.
> Cleanup could be optimized to look at an sstable and determine that all data within the
sstable does belong on a node, and therefore skip re-writing that sstable. This would make
cleanup essentially a noop in the case where all data on a node belongs on that node.
