[jira] [Created] (CASSANDRA-8603) Cut tombstone memory footprint in half for cql deletes

Dominic Letz created CASSANDRA-8603:
---------------------------------------

             Summary: Cut tombstone memory footprint in half for cql deletes
                 Key: CASSANDRA-8603
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8603
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Dominic Letz


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.
