[erlang-questions] is there anything wrong with global?

[Sean Cribbs]

Global registration is inherently a consensus problem, and thus will have
problems with liveness, as you've discovered. I can't speak to the
implementation of the 'global' module, but I would suspect it is not
partition-tolerant. Is there a way you can reconfigure your application to
have locally-registered processes (one-per-node), or not require a single
distribution point?

There is also some work done by my colleague Chris Meiklejohn for
eventually-consistent (and partition-tolerant) process groups, if you don't
require a single authoritative process:
