Reactive web services

Ahh, reactive, probably the buzzword of 2017, newer and shinier than good ol' microservices, all asynchronous, non-blocking and I've even heard some event-driven buzz around it. During this live-coding session we won't focus on the shiny nor on saving the world with dataflows using composable operators. Instead we'll focus on how the execution of this reactive approach differs from 'classic imperative approaches' and check how it impacts resource consumption and tps. We'll also see backpressure in action, cover the topic of reactive converters (e.g. JSON encoders and decoders) and check a couple of libraries, both new and old ones, that help build reactive web services.
