------------------------------------------

Is there still interest in moving this concept forward?  I am interested in exploring this option.

> 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.
