JOLT转换-将新元素命名为数组元素的值

编程问答 2022-08-11

问题描述

我不确定是否可以通过颠簸转换来实现。但是我想用随机顺序将json更改为具体名称：

输入json：

{
  "scheduler" : {
    "schedulerInfo" : {
      "usedCapacity" : 50.0,"queueName" : "root","queues" : {
        "queue" : [ {
          "type" : "capacitySchedulerLeafQueueInfo","usedCapacity" : 10.0,"queueName" : "jupyter"
        },{
          "type" : "capacitySchedulerLeafQueueInfo","usedCapacity" : 25.0,"queueName" : "spark"
          },"usedCapacity" : 15.0,"queueName" : "dremio"
          }
        } ]
      }
    }
  }
}

期望的结果：

{
"rootUsedCapacity": 50.0,"jupyterUsedCapacity": 10.0,"sparkUsedCapacity": 25.0,"dremIoUsedCapacity":15.0
}

我知道如何使其静态化，但是我不知道如何将“ queueName”的值添加到新的属性＆value + UsedCapacity：＆ArrayValue

静态解决方案：

[
  {
    "operation": "shift","spec": {
      "scheduler": {
        "schedulerInfo": {
          "usedCapacity": "rootUsedCapacity","queues": {
            "queue": {
              "0": {
                "usedCapacity": "jupyterUsedCapacity"
              },"1": {
                "usedCapacity": "sparkUsedCapacity"
              },"2": {
                "usedCapacity": "dremIoUsedCapacity"
              }
            }
          }
        }
      }
    }
  }
]

解决方法

用UsedCapacity字符串连接队列名称，然后使用usedCapacity移动新创建的节点，

[
  {
    "operation": "modify-default-beta","spec": {
      "scheduler": {
        "schedulerInfo": {
          "queues": {
            "queue": {
              "*": {
                "queueNameNew": "=concat(@(1,queueName),'UsedCapacity')"
              }
            }
          }
        }
      }
    }
  },{
    "operation": "shift","spec": {
      "scheduler": {
        "schedulerInfo": {
          "usedCapacity": "rootUsedCapacity","queues": {
            "queue": {
              "*": {
                "usedCapacity": "@(1,queueNameNew)"
              }
            }
          }
        }
      }
    }
  }
]
