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 think one of the key differences between DynamoDB and other NoSQL offerings is the provisioned throughput - you pay for a specific throughput level on a table and provided you keep your data well-partitioned you can always expect that throughput to be met. So as your application load grows you can scale up and keep you performance more-or-less constant.
