Kirk True commented on CASSANDRA-3974:
--------------------------------------
Sylvain - the main issue is that the code isn't structured in such a way that a
CFMetaData object is available.
Neither the code for QueryFilter.isRelevant nor its callers have access to a
CFMetaData. Can you think of a way to get the CFMetaData in there or a
different way to structure the code in general?

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