Reactive principles
As we begin this chapter, we shift our focus to reactive programming. This concept is fundamental to data streaming and forms the foundation for the work we will cover in this chapter. Rooted in functional programming, reactive programming allows us to shape our logic as a series of operations on a stream of data. The core tenets of this programming approach are encapsulated in the Reactive Manifesto, which you can read on the website (https://www.reactivemanifesto.org).
