Pretty cool deep-dive on Datalog.

The interactive tutorials on http://www.learndatalogtoday.org (Datomic's dialect) quickly sold me on the idea.

Though coming from Datomic, I'm curious how much of my knowledge is Datomic-specific rather than how you'd generally approach a database queryable with Datalog. For example, do you need four indexes like Datomic (https://docs.datomic.com/on-prem/indexes.html) to make Datalog queries fast?

If you have a lot of facts then you need indexes, otherwise you're scanning a lot of irrelevant data, many times over.

Sure, was just curious where Datomic's EAV, AEV, AVE, VAE indexes fall between Datomic indexing impl detail and general Datalog indexing solution.

Datalog is fascinating, but the blog post makes me curious about more concrete impl-related follow-up questions.
