Wow super psyched I got triple downvoted when I dared to say something mean against one of the great deathstar companies. I've noticed if I ever dare to say anything mean against amazon or google I get instantly downvoted. It is more reliable than a bot.
Anyway, dynamodb is insanely expensive compared to postgresql and I'd recommend only using it when you need to expose a datastore directly to the user as it's attribute based access control is easy to use. Postgresql serverless is now a thing as well. Anyway, if you truely want a WAN datastore, exposed to web clients, with attribute based access control, run dynamo.
