Dataweave 2.0 reduce function to reduce the array of json Mule

发布于 2020-12-16 01:45:04

My Input Json Looks like below :-

[{
        "eId": "123",
        "eType": "NZ",
        "value": [{
                "tId": "444"
            }, {
                "tId": "555"
            }
        ]
    }, {
        "eId": "456",
        "eType": "AU",
        "value": [{
                "tId": "666"
            }
        ]
    }
]

Expected Output Json to be like :

 [{
        "eId": "123",
        "eType": "NZ",
        "tId": "444"
    }, {
        "eId": "123",
        "eType": "NZ",
        "tId": "555"
    }, {
        "eId": "456",
        "eType": "AU",
        "tId": "666"
    }
]

I tried Transform using the reduce function like below. I am not getting expected response

%dw 2.0
output application/json
---
payload reduce ((val, acc = []) -> 
acc + {
    "id" : val.eId, "type": val.eType, "Tid": val.value map $.tId
})

Could someone please correct me where I am doing it wrong

I'll make an educated guess, because the example expected output is incomplete, that the expected output should look like:

[
  {
    "eId": "123",
    "type": "Co",
    "tId": "444"
  },
  {
    "eId": "123",
    "type": "Co",
    "tId": "555"
  }
]

Script:

%dw 2.0
output application/json
fun mapItem(i) = i.value map { eId: i.eId, "type": i.eType, tId: $.tId }
---
payload flatMap mapItem($)

Feel free to edit the question to add more details if needed.

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
