             Summary: Tiered HFile storage
                 Key: HBASE-6572
                 URL: https://issues.apache.org/jira/browse/HBASE-6572
             Project: HBase
          Issue Type: New Feature
            Reporter: Andrew Purtell


Consider how we might enable tiered HFile storage. If HDFS has the capability, 
we could create certain files on solid state devices where they might be 
frequently accessed, especially for random reads; and others (and by default) 
on spinning media as before. We could support the move of frequently read 
HFiles from spinning media to solid state. We already have CF statistics for 
this, would only need to add requisite admin interface; could even consider an 
autotiering option.
