AWS数据管道-RedshiftCopyActvity-Redshift到S3-设置为管道定界

Question

我已经建立了一个数据管道，每四个小时将一个表转储到S3文件中。一切都按预期进行。唯一的问题是，该文件用于加载另一个redshift表，该表正在寻找要填充的管道定界S3文件。我无权访问此表的Serde参数，因此需要强制将输出S3文件用Pipe（“ |”）分隔。

以下是用于创建管道的JSON：

{

    {
      "subnetId": "subnet",
      "resourceRole": "DefaultResourceRole",
      "role": "DefaultRole",

      },

      "tableName": "blah"

    {

      },
      "directoryPath": "s3://blah.com/blah/#{format(@scheduledStartTime,'YYYY')}/#{month(@scheduledStartTime)}",
      "name": "DefaultS3DataNode",
      "id": "S3DataNodeId",
      "type": "S3DataNode"
    },
    {
      "subject": "Load SUCCESS: #{node.@scheduledStartTime}",
      "name": "Load Success SNS",
      "id": "SuccessNotify",
      "message": "Successfully ran RedshiftCopyActivity #{node.name}.",
      "type": "SnsAlarm",
      "topicArn": "-"
    },  
    {
      "subject": "Load FAILURE: #{node.@scheduledStartTime}",
      "name": "Failed SNS",
      "id": "FailureNotify",
      "message": "FAILED: RedshiftCopyActivity #{node.name}.",
      "type": "SnsAlarm",
      "topicArn": "blah"
    }  
  ],
  "parameters": []
}

我需要为定界符创建一个“数据格式”部分，还是为s3节点创建类似“定界符”的标记？

谢谢。
