Curious: when would you choose DynamoDB over RDS / Aurora?

  Rick Houlihan has another talk from re:Invent 2018 where he goes into great detail about this -- see the following Twitter thread for a jumping off point. https://twitter.com/alexbdebrie/status/1081237474930769920 https://twitter.com/alexbdebrie/status/1081237474930769920

    I just finished watching that video 10 minutes ago and my mind is blown. I've been using DynamoDB wrong for most of 7 years.

    That's an awesome diagram, and I look forward to the video. I think this nicely illustrates why most projects shouldn't use a high-scalability NoSQL database: they benefit much more from flexible data models and efficient query. All that being said, there are other factors when choosing a database aside from those three. For some of our microservices, my team doesn't need scalability or flexible queries, just efficiency. However, we've found that it is cheaper/easier for use to use DynamoDB than RDS.

  If you write a lot you should probably use Aurora because less $$$.
