Mid-January, I held a talk at Kotlin.amsterdam based on my post Migrating from Imperative to Reactive (a Spring Boot application). Because it was a Kotlin meetup, I demoed Kotlin code, and I added a step by migrating the codebase to coroutines. During Q&A, somebody asked whether coroutines implemented backpressure. I admit I was not sure of the answer, so I did a bit of research. This post provides information on backpressure in general and how RxJava (v3), Project Reactor and Kotlin’

I don’t know if events became part of software engineering since Graphical-User Interface interactions, but for sure they are a very convenient way of modeling them. With more and more interconnected systems, asynchronous event management has become an important issue to tackle. With Functional-Programming also on the raise, this gave birth to libraries such as RxJava. However, modeling a problem as the handling of a stream of events shouldn’t be restricted to system events handling.
