Jean-Marc Spaggiari commented on HBASE-20105:
---------------------------------------------
Yes, sorry. A bit overwhelmed. Just received the SSDs. I will have to install
them to test it, and I will have to have a deeper look of Anoop's comment. Most
probably over the week-end.
> Allow flushes to target SSD storage

> 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.
