Cascalog

Cascalog is a powerful Clojure (and Java) data processing and querying library built atop Hadoop (via Cascading), providing a high-level, Datalog-inspired abstraction for both big data processing and local computation. Cascalog is hosted at Clojars, and some of its dependencies are hosted at Conjars. Both Clo/Con-jars are maven repos that's easy to use with maven or leiningen. The Cascalog website contains more information and links to Various articles and tutorials. The best way to get started with Cascalog is experiment with the toy datasets that ship with the project.

Features

Expressive, Datalog-like query language that runs on Hadoop or locally
Simplified abstraction over Cascading to avoid low-level Hadoop complexity
Seamless handling of distributed Big Data workflows
Pure Java API (JCascalog) available for Java integration and experimentation
Useful for prototyping data flows that scale from local tests to production clusters
Draws inspiration from existing tools like Pig, Hive, and Cascading while providing richer abstraction
