Rethinking GraphQL Execution

September 8, 2:25 – 2:55 PM

Grote Zaal - 2nd Floor

GraphQL in ProductionFederation and distributed systems

Session description

To ease life for the roughly 1,000 developers who contribute regularly to our GraphQL interface, Airbnb has a highly opinionated developer API that we believe eases life for both developers and the operators who maintain the service. In the past, this API was implemented on top of a traditional, specification-based GraphQL engine, which supported agility as we evolved our opinionated approach to resolvers. As that approach matured, we saw opportunities to build a more efficient engine to support them. This talk describes our new GraphQL engine. Key elements in our design include: - Refactoring query execution into distinct resolution and completion phases. - A query planner that optimizes and orchestrates the execution of those phases. - A new data structure that is the intermediary between the two phases, a data structure that allows for principled communication between the many resolvers involved in executing a query

Airbnb, Viaduct Tech Lead

Federation & distributed systems

Raymie Stata earned his PhD in Computer Science from MIT and has been building technology at the intersection of search, big data, and distributed systems ever since. He founded Stata Labs, an early pioneer in desktop search, which was acquired by Yahoo! where he rose to CTO and helped shape the Hadoop ecosystem. He later founded Altiscale, one of the first Big-Data-as-a-Service platforms, which was acquired by SAP. After serving as Airbnb’s first Technical Fellow and leading a broad re-engineering of their technology stack, Raymie is now focused on Viaduct — a project developed in close collaboration with Airbnb to bring GraphQL infrastructure to the next level.
