I'm currently evaluating different GraphQl servers in order to find one that supports subscriptions on a federated schema.
Apollo and HotChocolate don't support that. HotChocolate is going to (its on the roadmap) but I can't wait; and Apollo wants me to run a seperate subscription service which I'd like to avoid.
Anybody know of a service that allows me to use subscriptions this way, now? To be clear: I only need the federation server that supports subscriptions. The single schemas behind may still be served thru hot chocolate.
After some digging, I found this. Looks very promising. They claim to support subscriptions on federation.
