--------------------------------------
Reviewer: Benjamin Lerer
Reproduced In: 2.1.2, 2.0.11 (was: 2.0.11, 2.1.2)
> 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
> Labels: tombstone
> Attachments: cassandra-2.0.11-8603.txt, cassandra-2.1-8603.txt,
> cassandra-2.1-8603_v2.txt, system.log
>
>
> 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.
