Isn't the following case typical for dealing with Http().superPool(...) flows?
The superPool flow lets me nicely attach context to the HttResponse.
Now I do not want to materialize the getDataBytes Source right away but pass
it to flatMapConcat.
Like in the following pseudo java code:
1) Flow<Pair<HttpRequest, Object>, Pair<Try<HttpResponse>, Object>, BoxedUnit>
flow = httpClient.<Object>request();
2) Flow<Object, ByteString, BoxedUnit> byteStringFlow =
responseFlow.flatMapConcat(pair -> {
3) // How to also pass pair.second() back?
4) return pair.first().get().entity().getDataBytes();
5) });
In the above code I would like to also pass the context in pair.second()
downstream. I guess this is not possible with the simple flows api?
Does akka streams support a getDataBytes() with context flow?
