Document Model Support in DynamoDB: Flexibility, Availability, Performance, and Scale.Together at last

All Things Distributed

We are introducing native support for document model like JSON into DynamoDB, the ability to add / remove global secondary indexes, adding more flexible scaling options, and increasing the item size limit to 400KB. Now that we have added support for document object model while delivering consistent fast performance, I think DynamoDB is the logical first choice for any application. These databases trade off complex querying capabilities and consistency for scale and availability.
