Amazon DynamoDB support for empty values for non-key String and Binary attributes in DynamoDB tables is now available in the AWS GovCloud (US) Regions. Empty value support gives you greater flexibility to use attributes for a broader set of use cases without having to transform such attributes before sending them to DynamoDB. List, Map, and Set data types also support empty String and Binary values.
