The process of combining multiple GraphQL schemas (graphs) into a single GraphQL schema (graph).
The process of creating a single gateway from multiple underlying GraphQL services (Subschema), that orchestrates and delegates requests to the corresponding GraphQL services using The Guild’s graphql-tools/stitching libraries. Stitching supports all methods of type merging (Subschema Directive-based Type Merging or Programmatic/Config Gateway-based Type Merging) and thus also supports Apollo Federation.
An implementation of Subschema Directive-based Type Merging that is defined by the Apollo Federation Specification. GraphQL schemas (Apollo Federation Subgraphs) are composed of a single GraphQL schema (Apollo Federated Graph) on a Gateway level (Apollo Federation Gateway).

An implementation of Type Merging. The result of combining multiple Apollo federation Subgraphs is an Apollo Federated Graph. The Apollo Federated Graph is usually exposed via an Apollo Federation Gateway or Apollo Federation compatible gateway (e.g. graphql-mesh).
A service that exposes a GraphQL schema that is consumed by a gateway in order to create a federated graph. The services schema uses directive annotations on types and fields as a hint for a gateway on how it should combine the services schema with the schema of the other Apollo federation subgraphs. A Apollo Federation Subgraph is a GraphQL schema with Apollo Federation schema directives. Also See Subschema.
