Voyage II: Federating the Monolith

We'll take an existing monolith graph and transform it into a supergraph incrementally. We'll work with entities and interfaces as value types.

You can still follow along if your organization is on a different plan, but you won’t be able to complete certain hands-on tasks. You can also test out this functionality by signing up for a free Enterprise trial.
