Abstract

Applicatives and monads are all nice and useful, but sometimes seeing a novel way of employing them might deepen our understanding of the subject. This is what this talk aims for by showing a practical and somewhat unusual application of the Applicative abstraction.

We will look at the task of optimizing network calls — in this particular case, OpenTSDB queries — and show how using an Applicative interface enables us to design an API that's oblivious to the optimization processes, while still keeping the code purely functional.
