> once C* comes across a row tombstone, C* should check the TS on the tombstone 
> against all SSTables.  If the most recent TS in an SST is older than the row 
> tombstone, that entire SST (or the remainder of it) can be safely ignored.
> There are two drivers for this.
> * avoid checking column values that could not possibly be in the result set
> * avoid OOMing because all the tombstones are temporarily kept in memory.
