I would like to announce that I am actively developing an updated version of ScrappyDB that will also support Amazon DynamoDB as a backend. Functionality should be identical, and it should be transparent which backend you are using.
The primary differences are pricing and scalability:
- For a low volume site SimpleDB should be cheaper.
- For a high volume site DynamoDB should provide near infinite scalability with consistent performance.
Expected release date: "real soon now"
