Abstract :This article discusses the implementation of a Unified Supergraph for Distributed Data Graphs using the Apollo GraphQL Federation architecture, addressing the challenges of efficiently managing complex data sources within contemporary technological landscapes. With the Apollo Federation, multiple GraphQL APIs are seamlessly integrated into a unified Supergraph, providing developers with a scalable, modular, and interconnected approach. This article provides a detailed description of the components of the Apollo Federation, which includes Apollo GraphOS, Supergraph, Subgraph, RoverCLI, Apollo Router, and Managed Federation. Apollo GraphOS, provides a SaaS solution for schema registries, ensuring the integrity of underlying schemas, while Supergraph orchestrates and combines multiple subgraphs into one coherent GraphQL API. The Apollo Router serves as the public-facing interface for the Supergraph, while RoverCLI facilitates precise management and deployment of subgraphs. The Managed Federation simplifies the process of integrating and managing subgraphs, streamlining the process and ensuring consistency. A real-time demonstration of Apollo Federation with Netflix DGS is presented at the end of the article, which illustrates the framework's application in creating a unified Supergraph for Spring Boot applications. Organizations managing distributed data graphs can benefit from the advantages of Managed Federation, including router and composition stability, schema flexibility, and a real-time example using Netflix DGS.
