FastExport is a utility that uses multiple Teradata sessions to quickly export large amounts of data from a Teradata database. You can create a PowerCenter session that uses FastExport to read Teradata sources quickly. To use FastExport, create a mapping with a Teradata source database. In the session, use FastExport reader instead of Relational reader. Use a FastExport connection to the Teradata tables that you want to export in a session.
