Thirst-Quenching Streams for the Reactive Mind.
summary
Reactive Streams is a specification of four interfaces (maps to Java 9 Flow) that provides backpressure via Subscription rather than a ready runtime; implementations compared include Spring Reactor (Flux/Mono), RxJava2 (Flowable adds backpressure), Vert.x (polyglot event bus + verticle deployment), Akka, RSocket and MicroProfile. A polyglot Gateway verticle is built (Java/Kotlin/JS workers, SockJS bridge), deployed with Docker/Knative to OpenShift, and the demo runs while metrics show per-verticle counts and backpressure-controlled flow.
