JPA Data Access with Micronaut Data

When I have writing some articles comparing Spring and Micronaut frameworks recently, I have taken a note of many comments about lack of built-in ORM and data repositories support in Micronaut. Spring provides this feature for a long time through Spring Data project. The good news is that the Micronaut team is close to complete work on first version of their project with ORM support. The project called Micronaut Predator (short for Precomputed Data Repositories) is still under active development, and currently we may access just the snapshot version. However, the authors are introducing it is as more efficient with reduced memory consumption than competitive solutions like Spring Data or Grails GORM. In short, this could be achieved thanks to Ahead of Time (AoT) compilation to pre-compute queries for repository interfaces that are then executed by a thin, lightweight runtime layer, and avoiding usage of reflection or runtime proxies.
