Hello! I've asked a friend why they left Datomic Cloud for Postgres and this is his answer : A) useless documentation B) DIY tooling such as database backup (at that time) C) Contrary to on-prem, many things can only be done with Ions and they have their own requirements on workflow, infrastructure, etc, you must deal with lambdas And other reasons : - quite expensive compared to Pg - two i3 prod instances were ~ 5x slower than one M2 pg, despite optimizations - we actually needed a bi-temporal DB; we managed to replicate its versioning using pg snapshotting - support was slow and mostly we just heard "it isn't possible yet" What is your experience and thoughts?


yeah, datomic cloud seems interesting, but not that interesting... lack of excision is really strange, for example


I don't think I would really consider cloud, on-prem seems like the way to go

Yeah, for Europians excision is a big deal. I guess it misses because they have multiple layers of caching and would need to clear them all (though gdpr itself perhaps isn't that strict?)

Do you run on-prem in AWS?


no, just "normal" servers, and just free
