Transducers

Overview

Questions

• Aren’t there better abstractions to deal with parallelism, like map and reduce?
• What other libraries exist to aid in parallel computing, and what makes them special?

Objectives

• Exposure to some higher level programming concepts.
• Learn how to work with the pipe |> operator.
• Write performant code that scales.

List of libraries:

• Transducers.jl
• Folds.jl
• FLoops.jl

---

Key Points

• Transducers are composable functions.
• Using the |> operator can make your code consise, with fewer parenthesis, and more readable.
• Overusing the |> operator can make your code an absolute mess.
• Using Tranducers you can build scalable data pipe lines.
• Many Julia libraries for parallel computing and data processing are built on top of Tranducers.
