Datomic learning curve is relatively steep, like many higher level and more abstract things in Clojure ecosystem in general, and you should know how to cook it for sure. After figuring out all why's and how's it works like a charm. However, I indeed find Datomic Cloud version unnecessarily complex for most applications. Probably it is still a good corporate sales product for Cognitect.. Datomic On-premise version is much more friendly for small-medium-somewhat-larger use cases. Cloud version is also an AWS thing, so locks you in there, which is also not good.
