Introducing Cascalog: a Clojure-based query language for Hadoop

Amazing how many great looking projects are coming out of the Clojure community. I used to think that Scala was the heir apparent to Java but it seems like Clojure now has more momentum. Clojure has a kinder learning curve than Scala so perhaps that is the reason.

I'm tickled that their build system, a slicker replacement for Ant, is called Leiningen.<p><a href="http://zef.me/2470/building-clojure-projects-with-leiningen" rel="nofollow">http://zef.me/2470/building-clojure-projects-with-leiningen</a><p>It's a reference to the classic short story "Leiningen versus the Ants", which is a good read:<p><a href="http://www.classicshorts.com/stories/lvta.html" rel="nofollow">http://www.classicshorts.com/stories/lvta.html</a><p>And the build system looks <i>nice.</i> It has the pleasant feeling I get from scons, with the advantage of being Clojure-specific, so common Clojure tasks are easy.

Very neat. It would be even cooler if it had Pig's ILLUSTRATE. I suspect whichever REPL successfully completes an implementation of this: <a href="http://infolab.stanford.edu/~olston/publications/sigmod09.pdf" rel="nofollow">http://infolab.stanford.edu/~olston/publications/sigmod09.pd...</a> will emerge as the leader.
