test-and-set
------------
Key: CASSANDRA-48
URL: https://issues.apache.org/jira/browse/CASSANDRA-48
Project: Cassandra
Issue Type: Improvement
Reporter: Jonathan Ellis
Atomic test-and-set insert operation would be nice: "set value to X but only if
the current value is still Y." This allows a sort of optimistic consistency:
perform a GET, then perform test-and-set with the value of that GET as Y.
I do not think that this requires strong consistency to be useful.
