SDK Features

  • The Encoder and Decoder types have been enhanced to allow support for specifying the SDK's behavior when marshaling structures, maps, and slices to DynamoDB.
  • When EnableEmptyCollections is set to True the SDK will preserve the empty of these types in DynamoDB rather then encoding a NULL AttributeValue.

  • Non-Windows platforms will continue to employ a non-buffering behavior.
