@hiskennyness there’s also http://www.onyxplatform.org/ which might be useful for some use cases. I just finished moving some code I had that was using the report queue directly to a separate onyx process. Nice blog post here (http://www.stuttaford.me/2016/01/15/how-cognician-uses-onyx/) about using Datomic and Onyx

Followed Heroku buildpack https://elements.heroku.com/buildpacks/opengrail/heroku-buildpack-datomic to deploy a free Datomic transactor on Heroku, but getting this error:

Sigh, looks like "eth1" does not exist might have something to do with needing Heroku Spaces, which is only available on enterprise Heroku 🤕 lost half a day on this. Back to plain AWS
