What is Spring WebFlux?

Spring WebFlux is a reactive web framework that is part of the Spring Framework. It is built on a non-blocking, event-driven architecture and is designed to handle a large number of concurrent connections with fewer hardware resources compared to traditional, thread-based approaches. WebFlux is commonly used for building asynchronous and non-blocking web applications, microservices, and APIs where high concurrency and responsiveness are required. It supports reactive streams and provides functional programming paradigms for building web applications.
