Factual engineer Alex Robbins gave a presentation at Clojure/West this past week titled “Cascalog: Logic Programming over Hadoop.” His talk started with an introduction to Cascalog, moved on to a brief tour of its features, and then finished with writing a sample application. For those of you unfamilair with Cascalog, it’s a clojure library built on top of Hadoop that makes it easier to write distributed batch processing jobs. His slides and code examples are both available on github.
