How Is Message Recovery Done in Erlang/Elixir

Question

In the Erlang/Elixir Actor Model, if an actor sends a message but, for any reason (e.g. network failure, VM crash), it fails to reach the target actor, is there a way to replay that message or does the actor system regard that message as having been sent? Are messages guaranteed to be sent?

Answer 1

Delivery is not guaranteed, but order of delivery is. See http://erlang.org/pipermail/erlang-questions/2017-September/093564.html
