Also notable that Rego (the language in Open Policy Agent) [1] is a Datalog (or heavily inspired by) It's used in various policy evaluators (unsurprisingly) around access management, but also for gatekeeper [2] which allows security teams to define constraints around kubernetes resources, similarly conftest [3] can do the same for terraform For a lot of simple cases it's a fair bit more complicated (and unfamiliar) than tailored query languages, but really shines for matching over a complex graph of interlinking resources and then evaluating Boolean logic against the matches.
