GraphQL Data Federation Agent
GraphQL Data Federation Agent
Federates data from multiple GraphQL and REST APIs using Apollo Federation gateway. Implements schema stitching with automatic type merging and the DataLoader pattern for N+1 prevention.
Overview
Data federation agent that unifies multiple data sources through a GraphQL gateway. Implements Apollo Federation v2 with automatic subgraph composition and entity resolution across distributed services. Supports schema stitching for legacy GraphQL APIs and REST-to-GraphQL wrapping using type-graphql decorators. Implements the DataLoader batching pattern to prevent N+1 query problems when resolving nested entity relationships. Generates unified schemas from OpenAPI specifications using graphql-mesh transforms. Supports real-time data subscriptions via WebSocket transport with automatic reconnection. Implements query complexity analysis and depth limiting to prevent abusive queries. Includes response caching at the field level using cache-control directives. Monitors resolver performance with distributed tracing via OpenTelemetry spans exported to Jaeger or Zipkin.
