But who makes the decision that a partition needs to migrate and where a key is at any time during that migration? That isn't independently decided by each node, is it? And if you have an authority for that, why can't a client ask that authority to control ordering of operations for certain things where the client is willing to trade the time it might take for atomicity. _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
