Ok, I see on the Akka Gitter (https://gitter.im/akka/akka) a message by @drewhk which seems to confirm that we have to use materialized value to be notified of a stream completion, but it's to us to return something as a materialized value which can notify us.

You need support from the Sinks themselves to give you a signal (usually in the form of a materialized value) that they are done" My stream is an AMQP stream which never complete (it enriches messages), but it can fails so ATM I return a Future as a materialized value from my sink and on future failure, I terminate the actor system (because I want my service to fails to let other supervisor services handle this failure). He also wrote that "this is the topic of one of the upcoming blog posts", so I will see what is considered a good solution :) Le vendredi 9 septembre 2016 17:50:24 UTC+2, Victor a écrit : > > Hi, > > How can I terminate the ActorSystem running my stream when the stream > fails? > > If I have the following stream: > > A -> B -> C > > and B fails with a stoppingStrategy, what happens exactly?
