Agreed. It's wild to me how many people think they need arbitrary queries on their transactional database and then go write a CRUD app with no transactional consistency between resources and everything is a projection from a user or org resource -- you can easily model that with Dynamo. You can offload arbitrary analytical queries or searches to a different database and stop conflating that need with your app's core data source.

Well my experience has always been the opposite. New query patterns are always appearing. The difference between an OLTP and an OLAP query is not as clear cut as one might imagine that justifies huge changes to an existing system.
