Way too many teams choose Dynamodb too soon. Scalability, 0 management, coolness whatever. They don't realise until its too late that their application data needs are changing with feature requests and that with Ddb it implies doing 3D-chess each time to ensure the denormalised data is re-arranged the right way, rather than just using PostgreSQL with JSONB and adding an index, until/if it gets to FAANG scale, a bridge you can safely cross much later on.
