Json 如何在数组抖动中按值分组

我目前正试图在Jolt中执行一项操作，我认为如果我可以先按值对数据进行分组，这将是最简单的操作.我正在try 按值columnIndex对此列表进行分组

输入:

{
  "temp_sfp": [
    {
      "value": 600,
      "valueOperator": "=",
      "uom": "mcg",
      "name": "Vitamin D (as D3 Cholecalciferol)",
      "percentDvOperator": "=",
      "percentDv": "75.0",
      "columnIndex": 1
    },
    {
      "value": 2,
      "valueOperator": "=",
      "uom": null,
      "name": "Bacillus Coagulans",
      "percentDvOperator": "=",
      "percentDv": null,
      "columnIndex": 1
    },
    {
      "value": 300,
      "valueOperator": "=",
      "uom": "mcg",
      "name": "Vitamin D (as D3 Cholecalciferol)",
      "percentDvOperator": "=",
      "percentDv": "50.0",
      "columnIndex": 0
    },
    {
      "value": 1,
      "valueOperator": "=",
      "uom": "mg",
      "name": "Bacillus Coagulans",
      "percentDvOperator": "=",
      "percentDv": null,
      "columnIndex": 0
    }
  ]
}

帖子主题:Re:Колибри

{
  "sfp_group": [
    {
      "1": [
        {
          "value": 600,
          "valueOperator": "=",
          "uom": "mcg",
          "name": "Vitamin D (as D3 Cholecalciferol)",
          "percentDvOperator": "=",
          "percentDv": "75.0",
          "columnIndex": 1
        },
        {
          "value": 2,
          "valueOperator": "=",
          "uom": null,
          "name": "Bacillus Coagulans",
          "percentDvOperator": "=",
          "percentDv": null,
          "columnIndex": 1
        }
      ]
    },
    {
      "2": [
        {
          "value": 300,
          "valueOperator": "=",
          "uom": "mcg",
          "name": "Vitamin D (as D3 Cholecalciferol)",
          "percentDvOperator": "=",
          "percentDv": "50.0",
          "columnIndex": 0
        },
        {
          "value": 1,
          "valueOperator": "=",
          "uom": "mg",
          "name": "Bacillus Coagulans",
          "percentDvOperator": "=",
          "percentDv": null,
          "columnIndex": 0
        }
      ]
    }
  ]
}

在以前的帖子中，我try 了类似的方法来try 对列索引进行分组

{
  "operation": "shift",
  "spec": {
    "@1": "",
    "temp_sfp": {
      "*": {
        "columnIndex": {
          "*": {
            "*": {
              "@4": "&2"
            }
          }
        }
      }
    }
  }
}

但我还是想不明白
