-----------------------------------------
Summary: Support CAS
Key: CASSANDRA-5062
URL: https://issues.apache.org/jira/browse/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.
