Subject [jira] [Created] (HBASE-6572) Tiered HFile storage
Date Mon, 13 Aug 2012 21:32:37 GMT
Andrew Purtell created HBASE-6572:
-------------------------------------

             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.
