Ariadne and Managed Federation

[lorddaedra]

Typical use case: SPA application (TS, Vue.js, Apollo Client, VueApollo) + GraphQL API + internal microservices.

But with two architecture requirements for now.

1. Close integration with Apollo services. For example, Managed Federation feature (https://www.apollographql.com/docs/federation/managed-federation/overview/). It requires Apollo Server AFAIK.
2. Develop business logic using Python, do not refactor them to TS/JS.

Available ways:

1. Implement this feature for Ariadne (looks as expensive way, may require access to some Apollo private apis...)
2. Use Apollo Server as proxy between Apollo Client and Ariadne. It may require some js/ts coding, implementation of GraphQLThirdPartyDataSource.
3. Same thing, but with REST API: use Apollo Server with RESTDataSource + Starlette. Save time, RESTDataSource is implemented already.

What is your opinion? How to attach Apollo Server to python functions with business logic? Can Ariadne help me there?
