Denormalizing on one column

Procedure

Drop the following components: tFileInputDelimited, tDenormalize, tLogRow from the Palette to the design workspace.
Connect the components using Row main connections.
On the tFileInputDelimited Component view, set the filepath to the file to be denormalized.
Define the Header, Row Separator and Field Separator parameters.
The input file schema is made of two columns, Fathers and Children.
In the Basic settings of tDenormalize, define the column that contains multiple values to be grouped.
In this use case, the column to denormalize is Children.
Set the Delimiter to separate the grouped values. Beware as only one column can be denormalized.
Select the Merge same value check box, if you know that some values to be grouped are strictly identical.
Save your Job and press F6 to execute it.

All values from the column Children (set as column to denormalize) are grouped by their Fathers column. Values are separated by a comma.
