Got it working with this, still try to understand the last part (runForEach)
s.mapAsyncUnordered(3, new
Function<Pair<TopicPartition,Source<CommittableMessage<SpecificRecord,SpecificRecord>,NotUsed>>,
CompletionStage<Done>>() {
public CompletionStage<Done> apply(
Pair<TopicPartition,
Source<ConsumerMessage.CommittableMessage<SpecificRecord, SpecificRecord>,
NotUsed>> param)
throws Exception {
System.out.println("----------------part -----------------" +
param.first().partition());
Source<Message<SpecificRecord, SpecificRecord, Committable>, NotUsed> f
=
param.second().map(new
Function<ConsumerMessage.CommittableMessage<SpecificRecord,SpecificRecord>,
ProducerMessage.Message<SpecificRecord, SpecificRecord,
ConsumerMessage.Committable>>() {
public ProducerMessage.Message<SpecificRecord, SpecificRecord,
ConsumerMessage.Committable> apply(
CommittableMessage<SpecificRecord, SpecificRecord> msg)
throws Exception {
//System.out.println(Thread.currentThread().getName() +
"msg---------------------------------------------------" + msg);
System.out.println(Thread.currentThread().getName() +
"msg---------------------------------------------------" +
msg.record().value().getClass());
return new ProducerMessage.Message<SpecificRecord, SpecificRecord,
ConsumerMessage.Committable>(
new ProducerRecord<SpecificRecord, SpecificRecord>("akkatest",
msg.record().key(), msg.record().value()), msg.committableOffset());
}
});
return f.runWith(Producer.commitableSink(producerSettings),
materializer);
}
}).runForeach(new Procedure<Done>() {
@Override
public void apply(Done param) throws Exception {
}
}, materializer);
