Writing better APIs with MicroProfile GraphQL
summary
Shows MicroProfile GraphQL implemented with SmallRye implementation and a runnable Maven example (mvn clean install -P install), demonstrating selective field fetching that avoids expensive calls via deferred field resolution, plus full CRUD via mutations, schema generation and introspection-driven UIs. Includes concrete Java annotations (JSON‑B and GraphQL variants), logs proving conditional resolver invocation, simulated partial failures returning partial results with error locations, and an in‑memory demo dataset of 100 generated people to exercise list and filtering behavior.
