Eh, you "never, ever" have to worry about DynamoDB scaling in a perfect world where marketing is literally true. If you read Amazon's documentation, there's quite a lot that you need to pay attention to if you want DynamoDB to actually perform and scale well for your application. You don't get scalability for free. Tradeoffs and effort are always required. In Amazon's case you can usually throw money at the problem, but even that has its limits.
