If you're still interested here's an example of usage: https://github.com/rkrzewski/akka-cluster-etcd/blob/master/etcd-client/src/main/scala/pl/caltha/akka/etcd/EtcdClientImpl.scala#L98
In lines 78-97 an infinite source is constructed from a graph that has internal feedback loop. viaMat(FlowBreaker[EtcdResponse])(Keep.right) enriches the source with asynchronous termination capability. Materializing the stream with runWith(someSink) will produce a Cancellable value that you can use to terminate it at arbitrary time. Shutting down the Materializer is a coarse grained solution, but if you are running only a single stream at at time, it will work just fine.
