What are the pros and cons of DynamoDB with respect to other NoSQL databases?

Question

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

Answer 1

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 :)

Answer 2

Amazon DynamoDB seems like a pretty decent NoSQL solution. It is fast, and it is pretty easy to use. Other than having an AWS account, there really isn't any setup or maintenance required. The feature set and API is fairly small right now compared to MongoDB/CouchDB/Cassandra, but I would probably expect that to grow over time as feedback from the developer community is received. Right now, all of the official AWS SDKs include a DynamoDB client.
