I'm looking at this data stream api and I'm having a hard time working out
how this scheme fits into the pub sub model that micronaut uses. Here is
what I've kind of come up with and wonder if this would work.
@PubSubClientpublic interface MultipleMessage {
@Topic("animals")
public void send(@key() String key, Animal o);
@Topic("my_topic")
public void send2(@key() Long key, Object o);
}
@PubSubListener
public class SimpleSub {
@Subscription("animals")
public class Listener(@key() String key, Animal o) {
}
}
