-------------------------------------
Summary: camel-rxjava module should extend Bean Binding to support
methods returning Observable<T>
Key: CAMEL-9682
URL: https://issues.apache.org/jira/browse/CAMEL-9682
Project: Camel
Issue Type: Improvement
Reporter: james strachan
when making asynchronous InOut requests it'd be nice if methods could return
Observable<T> so that we could use the RxJava async programming model to
process async requests & responses.
e.g. kinda like how folks can use Retrofit for HTTP:
http://joluet.github.io/blog/2014/07/07/rxjava-retrofit/
{code}
public interface MyThing {
@GET("/session.json")
Observable<LoginResponse> login();
@GET("/user.json")
Observable<UserState> getUserState();
}
{code}
to then let you use the normal composition / join / flatMap stuff in RxJava to
compose multiple requests across different microservice invocations together
with timeouts etc e.g. to compose the latest from 2 calls:
{code}
Observable.combineLatest(api.fetchUserProfile(), api.getUserState(),
(user, userStatus) -> new Pair<>(user, userStatus));
{code}
Where we'd replace the @GET annotation with a bean binding annotation and a URI
parameter to switch to using ActiveMQ or Twitter or whatever
