震动:Nifi中的split/concat数组值 [英] Jolt: split/ concat array values in Nifi

问题描述

我正在Nifi中使用JOLT进行转换

I'm struggling with transformation using JOLT in Nifi

我的输入

[
  {
    "value0": 0,
    "value1": 1,
    "value2": 2
  },
  {
    "value0": 3,
    "value1": 4,
    "value2": 5
  }
]

所需的输出:

[
 {"val" :0 },
 {"val" :1 },
 {"val" :2 },
 {"val" :3 },
 {"val" :4 },
 {"val" :5 },
 ]

我几乎设法使它开始工作.这是我(错误的)震动规格:

I almost managed to get it to work. Here is my (wrong) Jolt Spec:

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "value*": "[&1].val"
      }
    }
}

 ]

这是我的结果:

[ {
  "val" : [ 0, 1, 2 ]
}, {
  "val" : [ 3, 4, 5 ]
} ]

谢谢！

推荐答案

尝试一下，

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "value*": "[].val"
      }
    }
}]
