AttributeValue

Represents the data for an attribute. Each attribute value is described as a name-value pair. The name is the data type, and the value is the data itself. DynamoDB supports scalar types (String, Number, Binary, Boolean, Null), document types (List, Map), and set types (String Set, Number Set, Binary Set).
