I am having problems getting Source.conflateWithSeed to work with ActorSink.actorRefWithAck in akka-typed
val conflateBufferSize = 100 val conflateFlow = Flow[Option[Message]] .filter(_.nonEmpty) .map(_.get) .buffer(100, OverflowStrategy.backpressure) .conflateWithSeed(seed = msg => Seq(msg))(aggregate = (accum, msg) => { val a = accum :+ msg println("Agg size= "+a.size) a }) .log("Conflated", _.size + " messages, buffer size="+conflateBufferSize) case class StreamMsg(sender: ActorRef[Protocol], msg: Seq[Message]) extends Protocol val replyTo:ActorRef[Protocol] = ... val actorSink = ActorSink.actorRefWithAck( ref = replyTo, onInitMessage = StreamInit, messageAdapter = StreamMsg, ackMessage = Ack, onCompleteMessage = StreamComplete, onFailureMessage = StreamFail ) Then i pipe conflated source messages to the actor messageSource .via(conflateFlow) .toMat(actorSink)(Keep.right) .run() No matter how much I slow down my actor sink ref object, I keep getting only a single message in StreamMsg(_, msg = Seq(Message(_)) and never the accumulated sequence in conflate I can't get it to pass conflated buffer to the actor sink in the StreamMsg Am I wiring component incorrectly? Any advice is greatly appreciated.
