This document discusses reactive frameworks including RxJava, Reactor Core, and Akka Streams. It outlines the interfaces for Publisher/Subscriber and different types of streams like Observable, Flowable, and Source. Spring WebFlux is also mentioned. Key types are compared between RxJava (Observable, Single, Completable), Reactor Core (Flow, Mono), and Akka Streams (Source, Sink, Flow).

16. The Interfaces
• subscribe() • onSubscribe(Subscription s)
• onNext(T t)
• onError(Throwable t)
• onComplete()
• request(long n)
• cancel()
• Extends Publisher and Subscriber

17. RxJava
• Observable (0 – N)
• Flowable (0 – N, but implements Publisher)
• Single (0 – 1)
• Completable (empty sequence)
Reactor Core
• Flow (0 – N)
• Mono(0 - 1)
• Mono<Void> (empty sequence)
Akka Streams
• Source
• Sink
• Flow
