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.
Data can be loaded from the following:
- Disk or tape files on a mainframe-attached client system
- Input files on a network-attached workstation
- Special input module (INMOD) routines written to select, validate, and preprocess input data
- Any other device providing properly formatted source data
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.
Full tape support is not available for any function in Teradata FastLoad for network-attached client systems. To import data from a tape, write a custom access module that interfaces with the tape device. For information about how to write a custom access module, refer to the Teradata Tools and Utilities Access Module Programmer Guide (B035-2424).
