Experience-Oriented Graphs with Batching
summary
Expedia Group maps UI components to an experience-oriented schema so each component exposes its own GraphQL operation, which creates many client queries; Apollo Client batches those into one HTTP request but the Apollo Gateway originally expands and concurrently executes each operation, causing separate subgraph calls and losing downstream dataloader batching. A custom RemoteGraphQLDataSource changes gateway->subgraph calls into true batches — demo shows subgraph calls dropping from four separate requests to two batched requests.
