Diving into Reactive: a live-coding adventure

Diving into Reactive: a live-coding adventure

Reactive programming offers developers a way to build message-driven, elastic, resilient, and responsive services...yet many developers don't know where to begin in order to leverage these capabilities. Spring and Project Reactor provide a great way to become immediately productive, going reactive from end to end.

In this live-coding adventure, you'll see you how to:

* integrate easily with existing Spring-stack technologies
* easily transition from blocking to reactive applications & systems
* define your API in an imperative style *and* functionally, reaping all benefits both ways
* leverage powerful new mechanisms to reduce blocking, improve testing, and increase scalability

    reactive programming is about non-blocking, event-driven applications that scale with a small number of threads with backpressure as a key ingredient that aims to ensure producers do not overwhelm consumers.”
