The wiki is a terrible place for proposals. Use the ML for those, and use JIRA when you start to actually generate code. https://issues.apache.org/jira/browse/CASSANDRA-580 is where Kelvin is working on vector clock support, which will handle eventually consistent increments. There is also a zookeeper module in contrib/ that you can implement atomic increment on top of. > p.s.

SimpleDB is key/row; dynamo is key/value. SimpleDB is Erlang; dynamo is Java. SimpleDB has a limit of 10GB/domain; there would be no need for such a low limit if it were based on Dynamo. -Jonathan
