 #### Return Data
-The data is returned with the same response syntax as the [DynamoDB BatchWriteItem API](https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_BatchWriteItem.html). If `autoExecute` and `autoParse` are enabled, a `.next()` method will be available on the returned object. Calling this function will call the `batchWrite` method again using the same options and passing any `UnprocessedKeys` in as the `RequestItems`. This is a convenience method for retrying unprocessed keys.
