Thank you, this is an important update. But the breaking changes from ScalaPB are a bit scary to push into a point release, as it upgrades ScalaPB and Akka HTTP.
The only excuse would be that Alpakka 3.0.0 is effectively broken as of #2680.

In #2613 (comment) @seglo mentioned that

Alpakka major releases don't have to be as rare as they are right now. If there's a good reason (and maybe this is one of them) then we could release an Alpakka 4.0.0 in a more reasonable interval, maybe after 3 months?

This update seems like it could be a good reason, along with the ability to make several other breaking changes (including to this module) that would complete the migration of all Google modules to google-common introduced in #2613. For example, google-pub-sub-grpc also currently has a vestigial dependency to the massive google-auth-library-oauth2-http although it is not used by the internal API (all auth runs through google-common now).

Yes, it's not ideal, even if it'd only affect users of akka-grpc-pub-sub-grpc that are already on 3.0.0 and use transitive dependencies that are on an older version of Akka gRPC. Without this change there is no version of akka-grpc-pub-sub-grpc that can coexist with Akka gRPC 2.0.0, which is not great either.

Thanks for your input @armanbilge.

We decided to postpone this update and will try to schedule another major release later in 2021.

Let's bring this PR back to live now!

I just merged the upgrade to Akka HTTP 10.2.9 with #2820

[ennru]

Rebased on current master.

[ennru]

What is breaking this build is the BigQueryMockServer which relies on the Akka gRPC generated power APIs for the server-side. Those APIs changed since Akka gRPC 1.0 and need to be updated for the new style.

Furthermore, it looks like Test / akkaGrpcGeneratedSources := Seq(AkkaGrpc.Server) doesn't kick in to generate the server code only for testing.

I don't have much time to spend on this, so please help out.

[ennru]

LGTM.

Thanks! 😁
