------------------------------------------
Summary: Transform operation
Key: CASSANDRA-6870
URL: https://issues.apache.org/jira/browse/CASSANDRA-6870
Project: Cassandra
Issue Type: New Feature
Reporter: Edward Capriolo
Assignee: Edward Capriolo
Priority: Minor
Compare and swap uses paxos to only update a value only if some criteria is
met. If I understand correctly we should be able to use this feature to provide
a wider variety of server side operations.
For example inside a paxos transaction performing a slice and then using a
function to manipulate the slice. You could accomplish features like append and
increment this way.
I took a stab at doing this. I **think** I did it correctly. Comments welcome.
