Finagle

Build request:

RequestBuilder requestBuilder = new RequestBuilder()   // custom class
                .withMethod(method)
                .withHeader(xxx, "xxx")
                .withPath(endpoint)
                .withParams(request.getPathParams())
                .withQueryParams(request.getQueryParams());

Service<Request, Response> restService = restServiceProvider.getService(serviceLabel);


Finagle Call:

        final Future<O> responseFuture = filter.apply(request, restService);
        final O result
        try {
            result = Await.result(responseFuture, Duration.fromMilliseconds(config.getTotalRequestTimeout()));
        } catch (Exception e) { ... }
         return result;
