It's been a while now but we saved about 10-100x moving from aurora to dynamo for a pure/simplish OLTP use case. Lost a lot of flexibility but the aurora costs were going to send us under. We also had a few issues where aurora was giving us *incorrect query results* and aws support were not helpful. Most of the issues were denied, even with simple reproductions, and then got fixed years later (~2-3) after we had given up. We still use it today but stay away from cutting edge features, unusual query patterns, and high volume use cases. Having said all that, SQL still seems like the correct choice for getting an MVP out quickly.
