Datomic, from Ruby, from Rails
summary
Datomic gets used from Ruby via the Diametric gem which exposes Datomic as an ActiveModel compliant layer, supports Rails scaffolding, and maps transactions and datalog queries into Ruby methods. JRuby uses the peer service for direct Java API access while MRI uses REST. The demo scaffolds, persists, and performs as-of rollback queries against thousands of facts so the setup works, but API coverage and idiomatic mapping remain incomplete and need PRs.
