Abstract

Monix started as a project exposing an idiomatic, opinionated and back-pressured ReactiveX implementation for Scala, but has grown beyond those boundaries to fully incorporate the lessons of functional programming.

I’m presenting a contrast between the Observable data type, which works with an underlying push-based and very efficient protocol and the new Iterant data type, a generic, purely functional, pull-based streaming alternative coming in Monix 3.0.

Besides outlining the direction of where Monix is going, the presentation is a lesson in functional programming design for FP enthusiasts.
