Jon Haddad commented on CASSANDRA-8460:
---------------------------------------
I'll be honest, whenever I need to do performance testing, the last thing I
reach for is stress, because I can't wrap my head around configuring it right.
It's probably easier to create a ~50 line program to do the inserts. I'll try
to throw something together tomorrow.
Ultimately if this is going to benefit TWCS, it *has* to be tested with it, so
we might as well do that up front.
It's the end of the day, and I'm not an expert in setting up lvmcache, so I'll
have to try it out tomorrow as well.

> 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.
