I'm told that Datalog is equivalent to SQL with recursive subqueries, which means that any Datalog query could be compiled to SQL. (Whether it's feasible to compile to efficient SQL, I don't know.)

I'm not aware of such a thing. Really this is based on my readings and few experiments, I'm not 100% sure that datalog can not be made faster and socialite (see below) seem to claim I'm wrong. Datalog is the native query language of datomic. I can put the finger on it, but I think there is a project for querying cassandra with datalog+clojure. This is the most recent work I'm aware of: - python querying of hadoop with a datalog-like language http://socialite-lang.github.io/ http://socialite-lang.github.io/ - overview: http://fr.slideshare.net/Hadoop_Summit/t-325p211seo http://fr.slideshare.net/Hadoop_Summit/t-325p211seo Also best way to learn datalog: http://www.learndatalogtoday.org/ http://www.learndatalogtoday.org/
