Apollo Federation 2 has been announced by the Apollo team, marking a major milestone in the evolution of their subgraph composition architecture. The new version builds on the success of the original with an improved shared ownership model, enhanced type merging, and cleaner syntax for a smoother developer experience. It's backwards compatible, requiring no major changes to your subgraphs. Federation 2 is designed in collaboration with the GraphQL community and adds first-class support for shared interfaces, enums, and other value types. The new version also includes deeper static analysis, better error messages, and new composition hints that help you catch errors sooner and understand how your schema impacts performance. With Federation 2, developers can deliver smaller increments with better shared types, federate subgraphs written in over 12 languages and frameworks, and power some of the largest graphs in the world, including Netflix, Walmart, RetailMeNot, and PayPal.
