API Composition Pattern Architecture
An API composition architecture diagram with a composer service that fans out parallel requests to multiple microservices, collects responses with timeout handling, and merges results into a single unified response with partial fallback support. This template models the API composition pattern used when a single client query requires data from multiple services, avoiding the need for direct service-to-service calls. Useful for teams building aggregation layers in microservices architectures.
