---------------------------------------
Summary: add CF level 'count based ttl' option
Key: CASSANDRA-4391
URL: https://issues.apache.org/jira/browse/CASSANDRA-4391
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.2
Reporter: Dave Brosius
Priority: Minor
Fix For: 1.2
It would be useful to have a column family level based ttl for columns based on
column count. This would be both lazy and sloppy, in that the only guarantee
you received was that the latest n columns would not be deleted.
When a compaction occurs, only up to n of the latest columns would be added to
the new sstable for any particular key.
So it is possible that old columns are removed out of order, but again, you can
be sure that the latest n columns are preserved.
