Overview of Reactive Programming Principles
Показать описание
This video gives an overview of reactive programming, which is an asynchronous paradigm designed to process and propagate streams of data in real-time applications. It's especially potent in user interfaces and latency-sensitive I/O operations, employing the concept of observables and observers or publishers and subscribers to emit and consume events. In modern web systems, reactive programming facilitates asynchronous communication between front-end API gateways and backend microservices. Reactive programming is built on four core principles: Responsiveness, ensuring quick and consistent event handling; Resilience, allowing fault tolerance; Elasticity, enabling autoscaling based on workload; and a Message-Driven architecture, which underpins the implementation through asynchronous message passing.
