Reactive Spring APIs

In this example-driven presentation, we'll focus on how to build reactive APIs in Spring. We'll start with Spring WebFlux, a reactive reimagining of the popular Spring MVC framework for HTTP-based APIs. Then we'll have a look at RSocket, an intriguing new communication protocol that is reactive by design.

Traditionally, applications have been built using a blocking, synchronous model. Although comfortable and intuitive for most programmers, this model doesn't scale well. And although there are several new approaches to reactive programming, they don't necessarily fit into the familiar programming model that Spring developers are accustomed to working with.

Spring 5 introduced a set of new reactive features, enabling non-blocking, asynchronous code that scales well using minimal threads. Moreover, it builds on the same concepts and programming models that Spring developers have used for years.
