In this 2021-11-22 workshop, @John_Newman introduced Injest:

John’s description:

> Note: This workshop covers material that is best understood by reviewing a prior workshop: “The Structure and Interpretation of Clojure Transducers”  
> Summary: Injest provides thread macros (e.g. x\>\>, =\>\>) that lower the bar to higher performance by letting you compose transducers in the same way as you would with -\>\>. In this workshop we will introduce you to injest’s three main features: path threads, auto transducification and auto parallelization. Then, we’ll go over some real-world examples of transforming (wrangling) data sequences. We’ll spend the remaining time of the workshop in an open session, answering questions and trying things out at the REPL. I might even wear a cowboy hat, in further jest 🤠

Many thanks, John, for the fantastic workshop, and everybody for the great discussion.

The recommended background is the transducers workshop by Ben Sless:
