FASTLOAD
Fast Load is a utility that can be used to quickly load large amounts of data to an empty table on Teradata. It uses multiple sessions to load data to the Teradata target table. FastLoad divides its job into two phases, both designed for speed. They are typically known as Phase 1 and Phase 2. Sometimes they are referred to Acquisition Phase and Application Phase.

PHASE 1: Acquisition
The primary function of Phase 1 is to transfer data from the host computer to the Access Module Processors (AMPs) as quickly as possible. When the Parsing Engine (PE) receives the INSERT command, it uses one session to parse the SQL just once. The PE is the Teradata software processor responsible for parsing syntax and generating a plan to execute the request. It then opens a Teradata session from the FastLoad client directly to the AMPs. Then by default, one session is created for each AMP.
