ConnectOnOpen | This property species whether to connect to the Amazon DynamoDB when the connection is opened. |
FlattenArrays | By default, nested arrays are returned as strings of JSON. The FlattenArrays property can be used to flatten the elements of nested arrays into columns of their own. Set FlattenArrays to the number of elements you want to return from nested arrays. |
