Federation and production GraphQL
Scale GraphQL across teams and services.
📖 Key ideas
- Federation combines many subgraphs into one supergraph.
- Each team owns its part of the schema.
- A gateway/router plans queries across services.
- Schema registries check changes before deploy.
- Monitor resolver timings and errors.
💡 Real-life example: Federation is a food court: many kitchens, one shared menu board for customers.
