Pavel Trukhanov commented on CASSANDRA-8460:
--------------------------------------------
Why can't we simply allow a CS instance to spread across two disks - SSD
and corresponding archival HDD, so it will see all the data for any
particular vnode at once and won't falsely ressurect something?
> Make it possible to move non-compacting sstables to slow/big storage in DTCS

> Key: CASSANDRA-8460
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8460
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Marcus Eriksson
> Priority: Major
> Labels: doc-impacting, dtcs
> Fix For: 4.x
>
>
> It would be nice if we could configure DTCS to have a set of extra data
> directories where we move the sstables once they are older than
> max_sstable_age_days.
> This would enable users to have a quick, small SSD for hot, new data, and big
> spinning disks for data that is rarely read and never compacted.
