Cascalog is a data processing library for Clojure that mixes functional and logic programming. It makes data processing code very concise, easier to grasp and reason about.
Being just a Clojure library, all of Clojures’ features are just a keystroke away – no need to learn another custom language (like Pig or Hive). This also allows for powerful abstraction and composition capabilities.
Although Hadoop being its major use case, Cascalog can be used for local data crunching as well. The talk will mainly focus on how Cascalog leverages logic programming, but real-life experience with Hadoop clusters will be mixed in as well.
