We are happy to announce that DynamoDB now supports two new data types: Binary and Binary Sets.
Using binary data types allows customers to reduce the size of items stored in DynamoDB. This helps customers lower costs in two ways:
To use binary data types, make sure you have the latest SDK libraries, which you can download at http://aws.amazon.com/code.
The EMR integration with DynamoDB does not yet support binary data types, but we will add this support shortly.
Getting started with Amazon DynamoDB is easy with our free tier of service. To learn more, visit the Amazon DynamoDB Page.
