ReactiveStreams and Java 9 Flow API support

[hantsy]

Please add ReactiveStreams(rxjava2, reactor, MP ReactiveStreams etc)and Java 9 Flow API support.

it could be designed like the .rx() method of JAXRS client, provide variants to openRxSession(<accept a impl type>).

[gavinking]

@hantsy we definitely want to supporting other options than just CompletionStage but I'm going to delegate thinking about precisely which ones we support to people like @cescoffier and @FroMage and @emmanuelbernard.

My only suggestion is that I guess we could have multiple RxSession interfaces in different packages, and you could choose which one to unwrap().

(A tangential issue is that we also need to support reactive database drivers other than the ones Vert.x provides.)

[emmanuelbernard]

That is something we need to discuss. if we go for Mutiny CC @cescoffier instead of CompletionStage, then Mutiny has bridges tot he other types and is an implementation of ReactiveStreams (for Publisher at least).

[gavinking]

Note that this is now a very easy thing for a user to contribute.

[cescoffier]

I agree with @emmanuelbernard :-)

[gavinking]

@cescoffier I already implemented a Mutiny-based API. It's documented in the readme and in the example program.

[cescoffier]

Cool! I will have a look!

Mutiny ... is an implementation of ReactiveStreams

Alright, so from what I can see here:

https://smallrye.io/smallrye-mutiny/

The Mutiny API does already let people easily use Hibernate Reactive with other reactive streams implementations.

Java 9 Flow API support

I don't know anything at all about this, but it also seems to be ReactiveStreams, so perhaps that's covered too. Anyway, we're targeting Java 8 for good reasons so we can't do anything specific with this API right now.

Look, I'm going to close this issue, since it's simply a bit too open ended.

Once someone has some real concrete use-case-driven experience, they can open new issues to request specific new APIs.

Right now I can't see what code I could possibly write that would let me mark this issue as "done". (Or rather, I probably already wrote the code when I added Mutiny.)
