Spring WebFlux: Reactive Web Framework for Non-Blocking Applications

Spring WebFlux is a reactive web framework introduced in Spring 5 that provides support for building non-blocking web applications. It's built on top of Project Reactor, a reactive library for building scalable and resilient applications. Spring WebFlux offers a reactive programming model for constructing web applications that can handle a large number of concurrent requests with low latency and high throughput. It supports both annotated controllers and functional programming styles for building web APIs. Spring WebFlux also provides support for reactive data access using reactive database drivers and reactive repositories.
