Sorting data when writing a JSON File
When writing a JSON file, data can be sorted with the use of sort keys.
This offers the possibility to order easily the data that is written in the JSON file with, if needed, multiple sort keys.
Metadata Configuration
The first step is to open the JSON Metadata to add the fields that will next be used in the Mappings to sort data.
For this simply add as many 'sortKey' Property Fields as required under the node that you want to sort.
The sort keys are applied in the order they are defined in the Metadata.
