Large cluster size
How big can a membase cluster get before the size of the node intercommunication starts causing problems? At some point it must be better to scale up the size of the nodes instead of adding additional nodes. For example, a 10-node cluster has 45 connections between servers which sounds reasonable to manage, but what happens if you've got 50 nodes (1225 interconnects), or 100 nodes (4950 interconnects), or even larger? Even a ballpark on what a reasonable largest cluster size should be would be appreciated.
