Transport: GraphQL over HTTP and beyond

episode 21 — GraphQL and Rust with Tom Houlé.

In this episode of Netstack.fm, Glen and Tom Houlé discuss GraphQL's transition from a high-hype mobile data solution at Facebook to a mature enterprise technology. They explore technical challenges like the N+1 problem and persisted queries, as well as the rise of GraphQL Federation for unifying microservices in Rust-based gateways. Tom also highlights GraphQL’s future potential as a self-documenting interface for LLMs and its healthy, community-driven development.
