> The idea is to use a qualifier to denote that all the columns of a specific
> family were deleted.
> Current implementation reads from HBase the entire family and then writes a
> tombstone to each one of its cells. The new implementation does not need to
> perform the read and only writes the qualifier to denote that the family was
> deleted. This is true only for Row level conflict detection since in Cell
> level we need to read the cells and add these to the write set.
