Easier Microservice Persistence With Micronaut Data

on YouTube ↗53m

" summary

Micronaut Data claims to precompute SQL at compile time using AoT query compilation so repository interfaces become concrete implementations with no reflection or runtime proxies. Demo shows a small Book app using the JDBC flavor with H2 for local testing then swapped to an Oracle Autonomous DB, implements CRUD, dynamic finder methods, pageable results and DTO projections compiled at build time. Also shows native-image builds that cut runtime memory and startup compared with a JVM JIT run.
