Which operator type is used to insert data into pre-existing Teradata tables with low latency?

The Stream Operator is specifically designed for inserting data into pre-existing Teradata tables with low latency. It allows for continuous, efficient data loading while maintaining the ability to handle live data streams. This is particularly useful in scenarios where timely data insertion is critical, such as real-time analytics or operational reporting. The Stream Operator works by capturing data from sources, such as files or message queues, and seamlessly integrating it into Teradata databases with minimal delay.

In contrast, other operator types serve different purposes that may not align with the need for low-latency data insertion. For instance, the Update Operator modifies existing records rather than inserting new data, making it unsuitable for the given requirement. Meanwhile, the Export Operator is used for extracting data from Teradata tables rather than inserting it. The Load Operator, while effective for loading large volumes of data, typically does not provide the same level of low latency that the Stream Operator does, as it generally involves batch processing rather than continuous data insertion.
