Anoop Sam John commented on HBASE-20105:
----------------------------------------
As per reply from [~rakeshr] in HDFS issue, this is possible. Not direct
setting while creating file and setting the policy on the file path explicitly.
We can play with this and see the gain. Are you going to experiment on this?
> Allow flushes to target SSD storage

> Key: HBASE-20105
> URL: https://issues.apache.org/jira/browse/HBASE-20105
> Project: HBase
> Issue Type: New Feature
> Components: Performance, regionserver
> Affects Versions: hbase-2.0.0-alpha-4
> Reporter: Jean-Marc Spaggiari
> Priority: Major
>
> On heavy writes usecases, flushes are compactes together pretty quickly.
> Allowing flushes to go on SSD allows faster flush and faster first
> compactions. Subsequent compactions going on regular storage.
>
> I will be interesting to have an option to target SSD for flushes.
