This document contains information about a presentation on full stack reactive Java using Spring Framework 5, Spring Boot 2, and Project Reactor. The presentation introduces reactive programming concepts like non-blocking and event-driven applications, and the key Reactive Streams interfaces of Publisher, Subscriber, Subscription, and Processor. It also provides an overview of Project Reactor and references code examples and additional resources on reactive programming.

“In a nutshell 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.”
