Bringing Reactive Programming to Java and Microservices

on YouTube ↗24m

" summary

Reactive programming here means building non‑blocking asynchronous Java services using the Reactive Streams spec (Java 9) and implementations like Reactor, RxJava and Vert.x; Spring WebFlux adopts Reactor core and exposes Mono/Flux publishers with operators, plus Netty as a non‑blocking server. The talk shows the Java evolution (threads → CompletableFuture → reactive streams), explains back pressure and subscription flow (subscribe → request → onNext/onComplete/onError), claims end‑to‑end reactive dependencies let a fixed small thread pool serve far more concurrent requests, and warns of a real learning curve and limited value for plain CRUD apps.
