如何在appflow中自动映射字段？

Question

我正在尝试通过云形成自动创建应用程序流。我在源中有多个字段（130+）并且我无法手动映射它。从 UI 中，我可以直接选择多个列，但从 cloudformation 中我必须指定，因此寻找是否有任何选项可以自动从源中获取所有列。

要映射所有字段，您必须将taskType与Map_all和 SourceFields 一起使用，并且任务属性将为空。

    tasks=[
        {
            'sourceFields': [],
            'taskType':'Map_all',
            'taskProperties: '{}'
        },
    ]
