Subj:   Re: Table Locking
 
From:   Newell, Ray

Teradata automatically chooses the locking level based on the number of AMPs. If you are doing all AMP operations, you will get table level locks. TPump uses row-hash locks because it requires the PI in the where clause resulting in single AMP operations.
