Json 取消嵌套数组并将数组名称添加为附加字段

Source JSON:个

{
  "dimensions": [
    {
      "apiName": "achievementId",
      "uiName": "Achievement ID"
    },
    {
      "apiName": "adFormat",
      "uiName": "Ad format",
      "category": "Publisher"
    }
  ],
  "metrics": [
    {
      "apiName": "active1DayUsers",
      "uiName": "1-day active users"
    },
    {
      "apiName": "active28DayUsers",
      "uiName": "28-day active users"
    }
  ],
  "name": "properties/317728157/metadata"
}

Expected:个

[
   {
      "apiName":"achievementId",
      "uiName":"Achievement ID",
      "metadata_object":"dimensions"
   },
   {
      "apiName":"adFormat",
      "uiName":"Ad format",
      "category":"Publisher",
      "metadata_object":"dimensions"
   },
   {
      "apiName":"active1DayUsers",
      "uiName":"1-day active users",
      "metadata_object":"metrics"
   },
   {
      "apiName":"active28DayUsers",
      "uiName":"28-day active users",
      "metadata_object":"metrics"
   }
]

我应该同时解套两个数组:dimensions和metrics.对于来自数组dimensions的每个对象，我应该添加字段metadata_object=dimensions.对于数组metrics-metadata_object=metrics中的每个对象.我可以用Jolt以一种不同的方式做到这一点:

[
  {
    "operation": "shift",
    "spec": {
      "dimensions": {
        "*": {
          "*": "[&1].&"
        }
      }
    }
  },
  {
    "operation": "default",
    "spec": {
      "*": {
        "metadata_object": "dimensions"
      }
    }
  }
]

但如何将两个数组一举结合起来呢？
