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.
