schema of the input component (tRowGenerator
in this case).
For the output structure, select Select an existing
hierarchical mapper structure, and then click Next.
Select the JSON_structure structure that you
created earlier, and then click Next and then
Finish.
In the Map editor that opens, drag row from
Input (Map) to person in
Output (JSON) to map each of the input
elements to its corresponding output element.
Double-click SimpleLoop in Loop tab and, in the properties box that opens, check
Stream Input and then click OK.
Press Ctrl+S to save your changes to the
map.
