Introduction

The Teradata Database provides several utilities to load, delete, or update large volumes of data. Utilities are the most efficient way to load data into a database. Utilities are designed to utilize the parallel architecture of Teradata while inserting, deleting, or updating data. This also means that if they are not designed properly, these utilities can have performance impacts on the system.

The following are the utilities in Teradata:

• Fastload: Bulk load utility
• Mload: Bulk load utility
• Fastexport: Bulk export utility
• BTEQ: Use of transient journal
• TPUMP: Use of transient journal

Let's see how these utilities compare with each other:

Utility Name	Type	Advantages	Disadvantages
Fastload	Single table bulk load	Fastest Table with NoPI supported Supports error limits and checkpoint/ restart Both support multi-value compression and PPI	Inserts only Empty target table required  Fallback, permanent journal are applied after the FastLoad is complete  Secondary indexes, triggers, join indexes, and referential...
