A Sink is a Graph; as is a Flow, and a Source - they're all graphs, of a specific shape. Here, the method takes a Graph<SinkShape, so yeah you can pass in a Sink.
Seems you're not passing in the materializer? In Java you have to do that explicitly: someSource.runWith(sink, materializer) -- Konrad `ktoso` Malawski Akka <http://akka.io> @ Lightbend <http://lightbend.com> On 28 April 2017 at 08:36:43, Shannon Ma ([email protected]) wrote: Hi, I am new to akka stream kafka, and am trying to follow some the examples to get start. I try to use Source.runWith(Sink.ignore()) or Soruce.runWith(Producer.commitableSink(producerSettings) and get this compilation error The method runWith(Graph<SinkShape<ConsumerMessage.CommittableMessage<SpecificRecord,SpecificRecord>>,M>, Materializer) in the type Source<ConsumerMessage.CommittableMessage<SpecificRecord,SpecificRecord>,Consumer.Control> is not applicable for the arguments (Sink<ProducerMessage.Message<SpecificRecord,SpecificRecord,ConsumerMessage.Committable>,CompletionStage<Done>>, null) The method expects Graph<>, but examples put Sink, what am i missing?
