> Memtable.resolve() uses the count of columns in the CF to bump the op count however RowMutation.delete()
does not add any columns to the CF when an entire row is deleted. If a super column or column
is deleted it adds 1 towards the op count. Deleting many named columns will add many to the
op count.
