CAS? just pass a assoc/commun Function to apply). - Again with types, pluggable type specific compression. - Wishy washy wish: Simpler "elasticity" I would like to go from 6-->8-->7 nodes without each of those being an annoying fight with tokens. - Gossip as library. Gossip/failure detection is something C* seems to have gotten particularly right (or at least it's something that has not needed to change much). It would be cool to use Cassandra's gossip protocol as distributed systems building tool a la ZooKeeper.
