Andrew Purtell commented on HBASE-12848:
----------------------------------------
Maybe we can combine this with HBASE-6572? If that one is just renamed to
"Tiered storage" then this could be a subtask of that, and figuring out what
would be useful to do with the SSD storage policy for HFiles would be the next.

> One way to improve data ingestion rate is to make use of Flash storage.
> HDFS is doing the heavy lifting - see HDFS-7228.
> We assume an environment where:
> 1. Some servers have a mix of flash, e.g. 2 flash drives and 4 traditional
> drives.
> 2. Some servers have all traditional storage.
> 3. RegionServers are deployed on both profiles within one HBase cluster.
> This JIRA allows WAL to be managed on flash in a mixed-profile environment.
