[jira] [Resolved] (CASSANDRA-7550) Reduce tombstones

     [ https://issues.apache.org/jira/browse/CASSANDRA-7550?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aleksey Yeschenko resolved CASSANDRA-7550.
------------------------------------------

    Resolution: Invalid

Unfortunately, it's not that easy. You can only do it if you are sure that there is nothing covered by the tombstone in any of the sstables on this, or any other node in the cluster.

> If a record is still in Memtable, the Delete to that record shall be done in memory (Make Compaction in memory), instead of placing a tombstone. This way it can save disk I/O and space a lot for records with short lifecycle.
