The De-normalizer transform allows you de-normalize data by looking up key-value pairs. It also allows you to immediately convert data types.
|Transform name||Name of the transform. This name has to be unique in a single pipeline.|
The field that defined the key of the output row.
Specify the fields that make up the grouping here.
Select the fields to de-normalize by specifying the String value for the key field (see above). Options are provided to convert data types. Strings are most common as key-value pairs so you must often convert to Integer, Number or Date. If you get key-value pair collisions (key is not unique for the group specified) specify the aggregation method to use.
You can use the Metadata Injection supported fields with ETL Metadata Injection transform to pass metadata to your pipeline at runtime. The following Value fields of the Row Denormaliser transform support metadata injection:
Target Filename, Value Fieldname, Key Value, Type, Format, Length, Precision, Currency, Decimal, Group, and Aggregation
