Introduction to Reactive Programming in Java with Project Reactor

Introduction to Reactive Programming in Java with Project Reactor we will go through below: 1. Introduction to Reactive Programming What is reactive programming? Key principles of reactive systems: Responsive : Systems should respond in a timely manner. Resilient : Systems should be fault-tolerant. Elastic : Systems should scale as needed. Message-driven : Systems should use asynchronous messaging. Comparison between imperative programming and reactive programming. 2. Understanding Reactive Streams Publisher , Subscriber , Subscription , and Processor interfaces. The four key signals: onNext() , onComplete() , onError() , and onSubscribe() . Backpressure handling in reactive systems. 3. Introduction to Project Reactor What is Project Reactor? Key classes: Mono and Flux . Mono : Represents 0 or 1 item. Flux : Represents 0 to N items. Non-blocking nature and how it helps in building scalable systems. 4. Building a Reactive Application with Project Reactor Demonstrating how to use Mono
