As you may recall from a previous blog post , Netflix has standardized on Spring Boot for backend development. Therefore, to make this federated architecture a success, we needed to have a great developer experience for GraphQL in Spring Boot. We created our framework on top of Spring Boot and it leverages the graphql-java library.
