Could not disagree more strongly that Datomic is well maintained. I'd view it as a significant liability in any organization using it without very good reason. My experience operationally supporting Datomic at even a moderate scale was a total nightmare and soured me on the Clojure ecosystem as a whole.
may i ask what you consider moderate scale in terms of daily/concurrent users? i’ve had no issue with small projects, but i’m curious to know where it starts falling over
