Namespacing Is the Next Frontier of GraphQL Federation - Martijn Walraven, Apollo

Tuesday September 9, 2025 11:00 - 11:40 BST

Studio

Although the topic of namespacing has been brought up repeatedly in the GraphQL community over the last decade, there is an understandable worry that it would lead to anti-patterns in schema design. If namespacing is used as an excuse to avoid coordination between teams, this can result in a fragmented GraphQL schema that reflects current team boundaries as opposed to domain or client concerns.

GraphQL Federation offers an alternative architecture: when coordination is enforced and consistency guaranteed, a large number of teams can contribute to a single, coherent GraphQL schema without the danger of stepping on each other's toes.

Even with that architecture in place however, I believe there are still legitimate use cases for namespacing. In this talk, I will go over some of those use cases, and formulate a set of design principles that could guide the introduction of namespacing in GraphQL.

The State of GraphQL Federation - Michael Staib, ChilliCream & Martijn Walraven, Apollo

Tuesday September 9, 2025 11:50 - 12:30 BST

Studio

The GraphQL community has come together to standardize how people can build distributed systems with GraphQL as an orchestrator. In this talk I will explain the general idea that we have for GraphQL as an Orchestrator in this space and how the new specification is tackling this. We will look at the progress we have made since last GraphQL Conf in the GraphQL composite schema working group and also get some sneak peaks at our early RFCs and prototypes. I will outline how this new specification is taking the best ideas of existing solutions in the market to make the next big leap towards mainstream adoption. This will allow anyone to build tooling by implementing the spec or parts of the spec that seamlessly integrate with other vendors.

Lower Latency With Streaming GraphQL - Rob Richard, 1stDibs

Tuesday September 9, 2025 14:00 - 14:40 BST

Studio

Learn how to lower latency in your applications by streaming your GraphQL responses using the @defer and @stream directives. Learn the trade-offs of when to use these new directives and how they differ from GraphQL Subscriptions.

@defer and @stream have been in development for some time now and have gone through many iterations. Learn about the motivation behind these changes and how they will lead to scalable GraphQL servers and efficient clients.

Speakers

Rob Richard

Senior Director, Front-End Engineering, 1stDibs

Rob is a front-end engineer at 1stDibs, an online marketplace for extraordinary design. He is also a member of the GraphQL Technical Steering committee, where he has been championing the @defer & @stream spec proposal.

The State of GraphQL Open Telemetry - Pascal Senn, ChilliCream

Tuesday September 9, 2025 14:50 - 15:30 BST

Studio

Curious about how observability is evolving in the GraphQL ecosystem? This session explores the current state of OpenTelemetry and its integration with GraphQL. We'll cover the fundamentals of OpenTelemetry, introduce the OpenTelemetry working group (https://github.com/graphql/otel-wg), and dive into tracing, logging, and metrics - all essential pillars of observability. You'll also learn how OpenTelemetry is being applied in distributed GraphQL architectures to improve performance monitoring and troubleshooting across services. Whether you're new to observability or looking to level up your GraphQL stack, this talk will bring you up to speed on where the community is heading.

Speakers

Pascal Senn

COO, ChilliCream

I'm co-founder of ChilliCream, where we're passionate about advancing the GraphQL ecosystem. We develop and maintain open-source software, actively help and participate in the community, and create tools that help developers to get the most out of their GraphQL APIs.
