Re: moving older tables from SSD to HDD?
Have you looked nodetool? http://www.datastax.com/documentation/cassandra/2.0/cassandra/tools/toolsNodetool_r.html 2014-08-04 16:43 GMT-03:00 Kevin Burton bur...@spinn3r.com: Is it possible to take older tables, which are immutable, and move them from SSD to HDD? We lower the SLA on older data so keeping it on HDD is totally fine. MySQL can *sort* of do this… and I think that Cassandra could if it was handled properly.

Re: moving older tables from SSD to HDD?
Hi Kevin, This is something we do plan to support, but don't right now. You can see the discussion around this and related issues here https://issues.apache.org/jira/browse/CASSANDRA-5863 (although it may seem unrelated at first glance).
