FULL PRIMARY INDEX - forum topic by Enzopre

HI at all
I´m new on Teradata and I'm studying the TPUMP utility from official documentation "Teradata Parallel Data Pump".
At some point in the chapter 1 section "What it Does" the document tells:
"The Teradata TPump task provides the acquisition of data from client files for application to
target tables through INSERT, UPDATE, or DELETE statements that specify the full primary
index."
What I want ask is, if possible, what's full primary index? What i know about database is primary index or UNIQUE primary index but I never heard full primary index!
Thanks in advance.
