Jolt转换规范输入

Question

我有以下输入json：

{
  "tags": {
    "event": "observation",
    "source": "hunter"
  }
}

输出JSON应如下所示：

{
  "tags" : [ "event:observation", "source:hunter" ]
}

任何人都可以就如何为上述内容构建适当的 Bump 规范提供任何指导吗？

非常感谢您的帮助 ^_^

您可以使用此规范

[
  { // combine each key-value pair under within common arrays
    "operation": "shift",
    "spec": {
      "tags": {
        "*": {
          "$": "&2_&1",
          "@": "&2_&1"
        }
      }
    }
  },
  { // concatenate key-value pairs by colon characters 
    "operation": "modify-overwrite-beta",
    "spec": {
      "*": "=join(':',@(1,&))"
    }
  },
  {
    "operation": "shift",
    "spec": { // make array key common("tags") for all arrays 
              // through use of _ seperator and * wildcard 
      "*_*": "&(0,1)"
    }
  }
]
