GraphQL downstream only?

[xma000]

Is it Nadel's intention to only combine GraphQL downstream services?

Can I somehow extend it with custom implementation? I have two use cases in mind.

• Calling a REST downstream service to fulfill a GraphQL query.
• Runtime switching between two GraphQL downstream services for ease of migration.

I think I find the answer. Nadel is only a library for combining schemas. It doesn't dictate how the queries are resolved. Application use Nadel by providing its own ServiceExcecutionFactory and ServiceExecutions.

Please confirm and elaborate as necessary.
