-------------------------------------

             Summary: very contentious writes result in performance degradation
                 Key: CASSANDRA-6943
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6943
             Project: Cassandra
          Issue Type: Bug
            Reporter: Russ Hatch
         Attachments: screenshot.png, screenshot2.png

Running performance scenarios I have seen this characteristic drop in performance happen several
times. A similar effect was reproduced in another test cluster. Operations eventually come
to a standstill.
