A Tale of Two Monix Streams — Scala Days, 2018, Berlin

Presentation from Scala Days 2018 by @alexelcu.

This is the second time this presentation was given. The first time it was delivered at Scala World in 2017.


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.

Required knowledge: Attendees need to have a good grasp of the Scala language. Some knowledge about FP libraries such as Cats is nice to have, but not required.

Learning objectives are to present where the Monix library is going and to teach real-world techniques for functional programming design that have helped in building the next iteration of the library.
