[jira] [Created] (CASSANDRA-11171) conditional update without paxos

stuart created CASSANDRA-11171:
----------------------------------

             Summary: conditional update without paxos
                 Key: CASSANDRA-11171
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11171
             Project: Cassandra
          Issue Type: Wish
            Reporter: stuart
            Priority: Minor


I realise that currently conditional updates use lightweight translation to provide an atomic check and set operation for conditional updates but that this comes at a non trivial performance cost. I have a solution where synchronised access is ensured by an external mechanism therefore I don't think paxos would be required. It would be nice to be able to run an update command or script that could conditionally update without the performance hit. Currently I'd have to retrieve each row first at the application level before deciding whether or not to perform the update. Would it be possible to add a switch for the conditional update to turn paxos on or off? Thanks.
