Overview of the Java Reactive Streams API

This video presents an overview of the Java Reactive Streams API. This API was introduced in Java 9 and provides the foundation for popular Java reactive programming frameworks, such as RXJava and Project Reactor, focusing on asynchronous, non-blocking data flows. Reactive Streams incorporate the Observer and Iterator patterns to enable a publisher-subscriber mechanism, facilitating efficient data exchange and flow control between data producers (publishers) and consumers (subscribers). Through the Flow API and its nested interfaces—Publisher, Subscriber, Subscription, and Processor—it offers a structured approach to handle data streams, allowing for dynamic flow control, error management, and lazy activation of streams. This API ensures interoperability among reactive programming frameworks by standardizing the core principles of reactive programming.
