Apollo Federation

Apollo Federation

Apollo Federation enables declarative composition of multiple subgraph APIs into a single federated supergraph. The Apollo Router orchestrates requests across subgraphs, combining GraphQL APIs and REST APIs (via Apollo Connectors) into a unified endpoint. Federation 2 defines the supergraph schema, federation directives, and composition rules. The Rover CLI manages schema publishing and checks.
