I don&#x27;t think that&#x27;s the problem though. The problem that I&#x27;m thinking of is that when a cluster grows in size, due to the use of consistent hashing, there&#x27;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 <a href="http:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1503.04988" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1503.04988</a><p>I&#x27;m not expecting to ever need to model a global property of &quot;these are the set of nodes that are up and running&quot;. I always worry about the effect of weird and wacky network issues on such systems.
