I am interested in Amazon’s new NoSQL database DynamoDB. We develop Android applications and a core requirement is scalable session management. This seems to be a primary use of DynamoDB.
Dynamo was born out of our need for a highly reliable, ultra-scalable key/value database. This non-relational, or NoSQL, database was targeted at use cases that were core to the Amazon ecommerce operation, such as the shopping cart and session service.
If I learn more I will add to this post but please feel free to comment.
