             Summary: time based compaction strategy
                 Key: CASSANDRA-5685
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5685
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Edward Capriolo


We have a column family with all sites ttl. The idea is that the odd data files would roll off after they are passed retention. What ends happening is they get compacted with new file and don't roll off. Leveled might help but still not perfect. 

Suggesting a compaction strategy that will not compact sstables together if the oldest and youngesr column are too far apart. This wilk 3nsure old data does not compact with new xata and help run closer to capacity.
