This is a restatement of your question, not an explanation for why a 1000 node cluster was the best way to solve your problem.
To be more direct: I think using 1000 erlang nodes is a bad idea for almost any system, and particularly when structured in a loop. I don’t think there are satisfying answers to the questions you are asking, because the questions you are asking involve a cluster architecture that is fundamentally bad.
If you can talk to us about the larger picture problems you are trying to face then perhaps we could provide some input. Otherwise I think this thread is at an impasse.
