My best guess is Datomic's coupling to the JVM makes it great for clojure developers (or java, scala etc) but not even considered by python or javascript shops, which make up the vast majority.
If python and java has better interop, I think the story would be a little different maybe? My experience is that java is always a little stubborn as "child code" so libaries like pyspark often involve notoriously difficult set up.
