Subject [jira] [Commented] (CASSANDRA-7550) Reduce tombstones
Date Tue, 15 Jul 2014 11:55:04 GMT


Aleksey Yeschenko commented on CASSANDRA-7550:

You can't (generally) know for a fact that a partition with the same key/a cell with the same
name doesn't exist elsewhere on disk or on another node.

> 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.
