Reactive for the Impatient - A Gentle Intro to Reactive Programming and Systems
summary
Quick practical intro that explains why reactivity aims for responsiveness, elasticity and resilience and shows concrete Java tooling: RxJava, Reactor, Akka, Vert.x. Covers the Reactive Manifesto and the Reactive Streams 1.0 spec, explains backpressure and circuit breakers, and proposes a working use case — a nonblocking ramen-order app where orders, seating and cook-ready notifications flow as streams. Notes a gap: most databases still lack true nonblocking I/O.
