Generated keys

Generated keys

The Normalizer transformation generates key values for normalized data.
Generated keys fields appear on the
Normalized Fields
tab when you configure the field to have more than one occurrence.
The
mapping
task generates the following fields for normalized data.
Generated Key
A key value that the task generates each time it processes an incoming row. When a task runs, it starts the generated key with one and increments by one for each processed row.
The Normalizer transformation uses one generated key field for all data to be normalized.
The naming convention for the Normalizer generated key is GK_<redefined_field_name>.
The generated key is not applicable in advanced mode.
Generated Column ID
A column ID value that represents the instance of the multiple-occurring data. For example, if an Expenses field that includes four occurs, the task uses values 1 through 4 to represent each type of occurring data.
The Normalizer transformation uses a generated column ID for each field configured to occur more than one time.
The naming convention for the Normalizer generated key is GCID_<redefined_field_name>.
An
advanced cluster
processes the generated column ID field as a bigint. The Data Integration Server processes the ID as an integer.
