We live in the age of high-load, where almost every Java Framework supports Reactive Programming paradigm and follows Reactive Manifesto principles. Not so far, Spring Framework provided mentioned feature as well. Unfortunately, most of us still have no experience in Reactive Programming, moreover, most of us have no idea what Reactive System is, and what is the difference between Reactive Programming and Reactive System, since both has word "Reactive". By attending the workshop, you will get a clear understanding of what is Reactive System and Reactive Programming, the difference between these notions, and will get practical experience using RxJava and Reactor 3.
