Andrei Ivanov commented on CXF-6833:
------------------------------------
Cool :)
The ugly surprise I had earlier with the Retrofit client was to discover that
the annotations they use are not the jax-rs ones, but their own with the same
name, so my attempt to reuse the service interfaces failed.
Would be nice to get a JAX-RS client usable on Android with reactive support.
What about {{CompletableFuture}}?
> support RxJava Observable<T> in return values as a more composeable
> alternative to Future<T>

> when invoking multiple REST services concurrently in a microservice kinda
> world it can be really helpful to use RxJava's Observable<T> so that you can
> easily compose concurrent asynchronous requests together.
> e.g. see this blog:
> http://joluet.github.io/blog/2014/07/07/rxjava-retrofit/
> Its basically about using RxJava's Observable<T> as the result type; which is
> a little like a Future<T> but can handle streams of values and is composable.
> It would be great to do this both on the client and server side; as a server
> may invoke multiple asynchronous back ends and return a composition of
> results etc.
> e.g.
> {code}
> @GET("/session.json")
> Observable<LoginResponse> login();
> @GET("/user.json")
> Observable<UserState> getUserState();
> {code}
> you can then use the Observable<T> composition methods to join / flatMap 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}
> and you're done! There's support for timeouts and other kinds of composition
> mechanisms too.
