Reactor 3, the reactive foundation for Java 8 (and Spring 5)
summary
Reactor 3 provides a concrete, non‑blocking runtime for Java 8 that implements the Reactive Streams rules and becomes the reactive foundation for Spring 5, Reactor Netty and Reactor Kafka. It exposes Flux (0..n) and Mono (0..1) types, a rich operator vocabulary (map, filter, flatMap, buffer, retry), scheduler control via publishOn/subscribeOn, and backpressure semantics so publishers honor downstream demand. Testing and debugging use StepVerifier with virtual time and checkpointing. The implementation is production‑ready and integrates into Spring and async IO stacks.
