I don't think that's the problem though. The problem that I'm thinking of is that when a cluster grows in size, due to the use of consistent hashing, there'll be a set of objects that need to move between nodes. Calculating and achieving that movement is what concerns me. The exact properties are explained early on in http://arxiv.org/abs/1503.04988
I'm not expecting to ever need to model a global property of "these are the set of nodes that are up and running". I always worry about the effect of weird and wacky network issues on such systems.
