Lars Hofhansl commented on HBASE-12934:
---------------------------------------
I think it's fine to move on with this one, as along as we do what we all
appear to agree now (keep a CF on SSD). Just flushes is useless (IMHO, as
usually) and hence I believe the initial idea of this jira was misguided.
We can keep this one closed and open a new one for that, or we can change this
jira to do that.
bq. We have an IN_MEMORY option for CF's. This should be similarly configured.
Exactly. That makes it simple and easy to understand.
And later we can add what Andy wants, namely that we can identify hot files or
regions and migrate those to SSD automatically.

> Store flushing should be able to make use of hdfs storage policy.
> One option is to allow setting storage policy for the directory path of the
