一个Data Pipeline中的多个表？

Question

【以下的问题经过翻译处理】 我正在使用Data Pipeline将来自RDS的数据复制到Redshift，对于每个表，都有一个单独的Pipeline进行复制。

是否可能将这些Pipelines合并为一个单独的Pipeline，用于多个表？如果可以，是否有一个示例JSON配置，可以实现这一点？

【以下的回答经过翻译处理】 是的，这是可能的。下面我包括了一个管道的演示JSON代码。

请注意，由于需要更多的MySql和Redshift属性，因此JSON不完整 - 我还包括了完整属性要求的链接。

MySql DataNode [要求]（https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-object-mysqldatanode.html）

Redshift DataNode [要求]（https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-object-redshiftdatanode.html）
