Spring WebFlux
Spring WebFlux is a reactive web framework built on Project Reactor, part of the Spring ecosystem, designed for non-blocking, asynchronous programming. It enables developers to build scalable, high-performance applications that handle concurrent requests efficiently using reactive streams. It supports both annotation-based and functional programming models for creating web applications.
Developers should learn Spring WebFlux when building applications requiring high concurrency, low latency, or real-time data processing, such as microservices, streaming APIs, or IoT systems. It is ideal for scenarios where traditional blocking I/O becomes a bottleneck, as it leverages reactive programming to improve resource utilization and scalability. Use it in Spring-based projects to handle thousands of concurrent connections with minimal thread overhead.
