[jira] [Updated] (CASSANDRA-3974) Per-CF TTL

["Kirk True (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-3974?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kirk True updated CASSANDRA-3974:
---------------------------------

    Attachment: trunk-3974.txt

This is a proof-of-concept patch for allowing optional default TTLs on a column family. 

I'm not sure how to implement the "compaction optimizations" the main JIRA description mentions.

Please provide feedback on what needs to be added/changed.

Thanks.

> Per-CF TTL would allow compaction optimizations ("drop an entire sstable's worth of expired data") that we can't do with per-column.
