Streamlining how you shop: Walmart and GraphQL

on YouTube ↗06m

" summary

Walmart moves from BFF-style standalone GraphQL services to a federated graph with a gateway, replacing duplicated item models so the item service owns item data and becomes the single source of truth. Development starts with standalone services, adds Federation and a gateway, then rolls out Android, iOS and web. The platform reaches 100% of eCommerce stack migration in 14 months, running roughly 20 subgraphs and enabling targeted scaling, stronger typing, and a single client entry point.
