Sylvain Lebresne commented on CASSANDRA-8603:
---------------------------------------------
Have you actually tested and validated that this was actually used? Because
unless I'm missing something no range tombstone generated by CQL should have
the same start and stop (it wouldn't entirely illegal to have a RT with the
same start and stop, but this RT would select a single cell and bug excluded,
we use cell tombstones for that case, not range tombstones).
> Cut tombstone memory footprint in half for cql deletes

> As CQL does not yet support range deletes every delete from CQL results in a
> "Semi-RangeTombstone" which actually has the same start and end values - but
> until today they are copies. Effectively doubling the required heap memory to
> store the RangeTombstone.
