Reactive Meets Data Access
summary
Spring Data K adds Java 8 baseline, Optional return types, renamed methods (findById, saveAll) and composable repository interfaces while shipping reactive CRUD repositories backed by Project Reactor and reactive drivers for MongoDB and Lettuce Redis; demo app (https://github.com/christophstrobl/spring-data-reactive-demo) builds an interval-based inserter plus REST endpoints, shows capped-collection tailing emitted as Server-Sent Events, and works live though caveats include Cassandra reactive over async and removed Jedis support.
