In the context of Teradata, what do AMPs primarily do?

In Teradata, Access Module Processors (AMPs) are essential components designed specifically for handling the retrieval of data and executing database functions. Each AMPs is responsible for a portion of the data stored within the Teradata database, making them crucial for parallel processing and ensuring high performance in data retrieval tasks.

When a query is executed, Teradata’s architecture distributes the work across multiple AMPs, allowing for simultaneous processing of data retrieval and other functions. This parallel approach minimizes response time and increases efficiency, as multiple AMPs can work on the same query at the same time by accessing the data they are responsible for.

As a result, AMPs not only retrieve data but also perform various database functions, including executing SQL statements, managing indexes, and handling data modifications. This role is vital to the overall performance and scalability of the Teradata system, especially when dealing with large amounts of data.

The other options, while related to database systems, do not accurately capture the primary responsibility of AMPs. For example, while network communications are crucial for the overall functioning of the database, they are typically managed by other components in the Teradata architecture. Similarly, user session management and data backup tasks are performed by different layers and processes within the Teradata ecosystem,
