Aurora did not work well for us (it was using local ephemeral disk to do sorts so our query results were truncated / limited to largest local storage) so the best option for us was to run MySQL or PostGres on a i3 instance with local SSDs.
Ok but I'm not sure this is relevant. We're talking about using Aurora in place of DynamoDB, not how it compares to other SQL DBs. With DynamoDB the kind of internal sort you're talking about isn't even possible, right?
