Flatten Record Transformation
The Flatten Record transformation plugin is available in the Hub (Hierarchy Plugins).
Plugin version: 1.0.0
The Flatten Record transformation flattens nested data structures.
You can use this transformation to convert a nested data structure into a single flattened record where each key in the record is a _
 name path to the node in the nested structure.
Note: The plugin supports the flattening of records only. In order to flatten an array of records, first use Wrangler Flatten directive to flatten the array and then use the Flatten Record transformation.
