hi Jaret, while you are looking at datomic pro scripts - i want to donate the user interview setup scripts we wrote and have been using for a year or two. We also use them in our prod demo environments - CICD pipeline

This repo https://github.com/hyperfiddle/datomic-browser contains three scripts

datomic_fixtures_mbrainz_full.sh
datomic_fixtures.sh (todo rename to _mbrainz_small)
run_datomic.sh

The value of these scripts is they get a prospective user from zero to working mbrainz instance in about 60 seconds, reliably and while under pressure, preventing a number of common mistakes, typos, issues and hurdles

Missionary concept map

Missionary primitives fit into three categories:

Effect descriptions = pure functional programming which is about trees not graphs

continuous flow, m/?< (switch)
m/watch, m/latest, m/cp
m/observe
m/reductions, m/relieve
