            Note Column names must match field names specified in the ETL file requirements. Attributes must exist in the Personalization system and must be prepended with attribute:. To learn more, see Available ETL Data Feeds.
            The following example shows configuring an ETL data feed for user or subscriber data (see User ETL Data Feed). The first column is required, maps to an identity attribute, and is configured as the primary key. The remaining columns are mapped to other user attributes.
            Note
            Note When defining data extension fields, don’t specify a value of Date for any attribute data types.
