The newly released GraphOS Platform APIs enable blue-green and canary deployments, allowing organizations to streamline their integration with immutable workflows. These enhanced APIs provide a versatile solution for deployment strategies, supporting both blue-green and canary releases. The new features include PublishSubgraphsMutation, PollLaunchStatusQuery, and FetchSupergraphSDLQuery, which allow teams to publish subgraphs as a single unit, poll for launch status, and fetch supergraph schema of the launch. With these updates, platform teams can enhance their GraphQL platform stance and deploy with greater flexibility, while also ensuring compatibility with existing workflows that rely on immutable schemas.
