The exporting ability of the Export operator is designed to outperform the SQL Selector operator (similar to BTEQ Export) in transferring large amounts of data from Teradata tables.

This is so because, among other factors, the Export operator is multisessioned and able to run in multiple parallel instances. It performs block exports in contrast to the SQL Selector operator, which performs single-session and one-row-at-a-time exports.

Export functions in Teradata PT do not make Teradata Database perform faster. Rather, Teradata PT allows for the greater use of multiple parsing engines and AMPs.
