Federated Gateway implementation using Golang instead of Apollo Node.js?

Docs: https://gqlgen.com/recipes/federation/

The Federated Gateway is just using Apollo on a Node.js server. One of the main reasons I would choose Go is for performance, but looks like using Node.js as Federated Gateway, Node.js becomes the bottleneck.

Is there a Golang implementation for Federated Gateway?

I use a variant of the example from here: https://github.com/wundergraph/graphql-go-tools

It even supports subscriptions.

@argoyle In this file: https://github.com/wundergraph/graphql-go-tools/blob/master/examples/federation/gateway/main.go

it have:

// It's just a simple example of graphql federation gateway server, it's NOT a production ready code.

What would be necessary to have a production ready code? Or what would be necessary to change to achieve it?

[argoyle]

I guess that depends on your requirements for production ready. I've made minor changes here and there to suit my own code style etc but no major changes.

For what it's worth, Apollo now has apollo-router which is a federation router built in Rust. It does not support subscriptions at this time, though.
