Multiple tables can be targeted by a single Teradata TPump job.

If the script author is uncertain whether or not to use ROBUST restart logic, it is always safe to use the ROBUST ON parameter.

To ensure data integrity, the SERIALIZE parameter defaults to ON in the absence of an explicit value if there are upserts in the Teradata TPump job.

The statement rate per minute you set using the RATE keyword is also affected by the periodicity value. By default, Teradata TPump uses a periodicity value of four when enforcing the statement rate limit. You can adjust the periodicity rate from 1 to 1500 using a runtime parameter.

For example, if you set the statement rate at 1600 and the periodicity at 10, then the maximum number of statements processed is 160 (1600/10) statements every 6 (60/10) seconds.

A LOGOFF command entered after a BEGIN and before the matching END LOAD logs you off the Teradata TPump utility.
