Distributed publish using gproc w/o gen_leader
Re: [erlang-questions] gproc and gen_event
Of course, for a distributed pub/sub, you don't really need to turn on
the distributed parts of gproc. Running a local gproc instance on each
node, you can publish like so:
publish(Event, Data) ->
rpc:eval_everywhere(
gproc, send,
[{p, l, {?MODULE, Event}}, {?MODULE, Event, Data}]).
