" summary

Live demo shows a Beer Advisor backend with queries, mutations and real-time subscriptions via WebSockets that update two browser windows when a rating is posted. Implementation details: core is graphql-java with DataFetcher functions, higher-level options include graphql-java-tools, Spring GraphQL (beta Jul 2021) and Netflix DGS (Feb 2021), and MicroProfile GraphQL offers code‑first annotations. Schema is SDL by default, subscriptions require a Reactive Streams Publisher, and example code plus a GraphiQL IDE are published in the GitHub repo.
