Apparently it is not easy to create general purpose datalog engines that scale.

"In this paper, we started with the observation that Datalog engines do not translate across domains. We experimentally evaluated the advantages and disadvantages of existing techniques, and compared them with our own baseline, a general-purpose, parallel, in-memory Datalog solver (RecStep) built upon a rdbms.

"We presented the necessary optimizations and guidelines to achieve efficiency, and demonstrated that RecStep is scalable, applicable to a range of application domains, and is competitive with highly op- timized and specialized Datalog solvers."
