We use MongoDB database add-on on Heroku for our SaaS product. Now that Amazon launched DynamoDB, a cloud database service, I was wondering how that changes the NoSQL offerings
I have to be honest; I was very excited when I heard about the new DynamoDB and did attend the webinar yesterday. However it's so difficult to make a decision right now as everything they said was still very vague; I have no idea the functions that are going to be allowed / used through their service.
The one thing I do know is that scaling is automatically handled; which is pretty awesome, yet there are still so many unknowns that it's tough to really make a great analysis until all the facts are in and we can start using it.
Thus far I still see mongo as working much better for me (personally) in the project undertaking that I've been working on.
Like most DB decisions, it's really going to come down to a project by project decision of what's best for your need.
I anxiously await more information on the product, as for now though it is in beta and I wouldn't jump ship to adopt the latest and greatest only to be a tester :)
