Which operator is responsible for high-volume maintenance transactions in Teradata?

The Update Operator is specifically designed for high-volume maintenance transactions in Teradata. This operator efficiently modifies existing records in the database, handling bulk updates in a manner that optimizes performance. It is capable of updating multiple rows at once, making it ideal for large-scale data modifications where efficiency and speed are critical.

In contrast, the Load Operator focuses on loading data into a Teradata database, primarily used for inserting new records rather than updating existing ones. The Export Operator is utilized to extract data from Teradata, which does not involve any maintenance or updates to the data. The Stream Operator is geared toward managing real-time data streams, therefore not directly applicable to bulk maintenance tasks that involve high-volume updates. This distinction clarifies why the Update Operator is the correct choice for handling high-volume maintenance transactions.
