If your application needs a lot of locking, it is probably not ideal for a distributed, log structured database with immutable data files. That said, Cassandra 2.0 will support CAS via Paxos. Presumably at a much, much lower throughput than the base system. https://issues.apache.org/jira/browse/CASSANDRA-5062 =Rob
