>             Project: Cassandra
>          Issue Type: Wish
>            Reporter: stuart
>            Priority: Minor

> I realise that currently conditional updates use lightweight transactions to 
> provide an atomic check and set operation 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 updates to turn paxos on or off? Thanks.
