Marcus Eriksson commented on CASSANDRA-5514:
--------------------------------------------
i like it, it would go very nice with CASSANDRA-5228 and an "age tiered"
compaction strategy
> Allow timestamp hints

> Key: CASSANDRA-5514
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5514
> Project: Cassandra
> Issue Type: New Feature
> Components: API, Core
> Reporter: Jonathan Ellis
> Fix For: 2.0
>
>
> Slice queries can't optimize based on timestamp except for rare cases
> (CASSANDRA-4116). However, many common queries involve an implicit time
> component, where the application author knows that he is only interested in
> data more recent than X, or older than Y.
> We could use the per-sstable max and min timestamps we track to avoid
> touching cold data if we could pass a hint to Cassandra about the time range
> we care about.
