Which component of Teradata handles Session Control functions?

The component of Teradata that handles Session Control functions is the Processing Elements (PEs). PEs are responsible for managing user sessions and executing user queries. They facilitate communication between the user applications and the Teradata system by managing connections, distributing workload, and ensuring that data requests are processed accurately.

PEs play a crucial role in session management by maintaining session states, tracking session identifiers, and overseeing the execution of queries associated with those sessions. They also manage the allocation of resources necessary to process requests efficiently.

In contrast, other components like AMPs (Access Module Processors) focus primarily on retrieving and processing data from the database, while the BYNET is a networking layer that handles data communication among different components, including transferring data to and from the user applications. LAN Connections represent the network infrastructure but do not directly handle session management or control. Thus, the PEs are central to the function of session control in a Teradata environment.
