Teradata FastLoad is a command-driven utility which can be used to quickly load large amounts of data in an empty table on a Teradata Database.
Teradata FastLoad uses multiple sessions to load data. However, it loads data into only one table on a Teradata Database per job. To load data into more than one table in the Teradata Database, multiple Teradata FastLoad jobs must be submitted—one for each table.
