Create Key: Pair value in mapper

[akarsh]

Input Structure

[
{
"Id": "ABC",
"IFA_Number__c": "1"
},
{
"Id": "BCD",
"IFA_Number__c": "2"
}
]

I have to save this data in a key value format ( Ifanumber is key and ID is value) so that later in mapper I have to fetc fetch the respective ID based on IFA number. what's best way to do this?

Hello @akarsh,

You can try with grouping all of the documents into a single array, then using reduce to combine them in one object.

Please note that if you have duplicate keys through the documents, they will overwrite.

Please refer to the attached pipeline and let me know if this helps you.

Aleksandar.

Thanks a lot, it worked.

@Aleksandar_A  there is a possibility that IcustomerIFANumber might not be present . is there a way to skip the mapping when its not present? 
$dataList.map(x => x.customerIFANumber != null ? x.customerIFANumber : null).filter((x,ind,arr) => arr.indexOf(x) == ind).toString()

Hello @akarsh,

Could you please share an example of your input and the expected output?

Sorry I posted the question in wrong thread.

input will be like this

{
"totalCount": 4,
"dataList": [
{
"IfaNumber": "1",
"alink": "",
"agroupId": ""
},
{
"IfaNumber": "2",
"alink": "",
"agroupId": ""
},
{
"IfaNumber": "3",
"alink": "",
"agroupId": ""
},
{
"alink": "",
"agroupId": ""
}
]
}


Output
["1","2",3"]

You can try with the following expression:

$dataList.map(x => x.get('IfaNumber',null)).filter((x,ind,arr) => x != null && arr.indexOf(x) == ind)

Let me know if this helps.
