Subject [jira] [Created] (CASSANDRA-5062) Support CAS
Date Thu, 13 Dec 2012 15:26:12 GMT
Jonathan Ellis created CASSANDRA-5062:

             Summary: Support CAS
                 Key: CASSANDRA-5062
             Project: Cassandra
          Issue Type: New Feature
          Components: API, Core
            Reporter: Jonathan Ellis
             Fix For: 2.0

"Strong" consistency is not enough to prevent race conditions.  The classic example is user
account creation: we want to ensure usernames are unique, so we only want to signal account
creation success if nobody else has created the account yet.  But naive read-then-write allows
clients to race and both think they have a green light to create.
