What are good/established database backing strategies for logic programming in clojure

I'm having a hard time finding profound information on strategies to set up a (deductive) database for facts to be queried using a logic programming approach like core.logic. Most examples to be found deal with facts created in memory.

A really nice library out there is Cascalog. It sits on top of hadoop and abstracts away the map-reduce with a nice and intuitive query language inspired by datalog.

But Cascalog is hadoop only and I wonder if there are similar clojure solutions which go well with other types of databases, be it nosql or relational (deductive databases).

This blog post show how write relations that query from a data source:

Using the ideas there, I was able to write relations to query from MongoDB and Redis.
