Jeremy Hanna created CASSANDRA-9517:
---------------------------------------

             Summary: Switch to DTCS for hint storage
                 Key: CASSANDRA-9517
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9517
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Jeremy Hanna


The DateTieredCompactionStrategy is a good choice for HintedHandoff so that we reduce the compaction load we incur when users build up hints.  [~atobey@datastax.com] and others have tried the following patch in various setups and have seen significantly less load from hint compaction.

Setting the time window to 10 minutes has shown additional improvement.

[~krummas] do you have any feedback about this idea and/or settings?
