I'm using akka-kafka with committablePartitionedSource, meaning I have a source of (partition, innersource) tuples.
I'm currently using the flatMapMerge recipe from https://doc.akka.io/docs/akka-stream-kafka/current/consumer.html#source-per-partition val done = Consumer.committablePartitionedSource(consumerSettings, Subscriptions.topics("topic1")) .flatMapMerge(maxPartitions, _._2) .via(business) .batch(max = 20, first => CommittableOffsetBatch.empty.updated(first.committableOffset)) { (batch, elem) => batch.updated(elem.committableOffset) } .mapAsync(3)(_.commitScaladsl()) .runWith(Sink.ignore) If I have a default supervision strategy which resumes, set at the materializer level, but want to stop the stream (which in my case restarts a host actor with backoff) at the source level, do I need to do a withAttributes(attributesForStoppingDecider) at both the outer source and inner source leves? i.e. val done = Consumer.committablePartitionedSource(consumerSettings, Subscriptions.topics("topic1")) .withAttributes(attributesForStoppingDecider).flatMapMerge(maxPartitions, _._2.withAttributes(attributesForStoppingDecider)) .via(business) or can I do it after the flatMapMerge? Question motivated by this open ticket which I'm not sure I fully understand yet. https://github.com/akka/akka/issues/23066 -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
