Easier Microservice Persistence with Micronaut Data
summary
Micronaut Data claims AoT compilation that precomputes SQL at build time and avoids reflection, demonstrated by building a Book entity, a CrudRepository (JDBC flavor) and a controller backed by an H2 in‑memory DB with four bootstrap records; CRUD and custom queries by method name work without handwritten SQL, DTO projections and @Query native SQL (LIMIT 2) also work, pagination is built in, and a native image shows much faster startup and lower memory (Micronaut Data, H2 in-memory DB, native image startup 79ms).
