In Teradata's parallel environment, response time is as fast as
-
the fastest AMP invloved
-
slowest AMP involved
-
sum of all amps involved
-
average performance of all AMPs
To answer this question, the user needs to know about Teradata's Parallel Environment.
In Teradata's Parallel Environment, the response time is determined by the slowest AMP involved in the process. This is because the Teradata system is designed to ensure that all AMPs are involved in processing a query or transaction, and the system waits for the slowest AMP to complete its task before returning the results to the user.
Therefore, the correct answer is:
The Answer is: B. slowest AMP involved
In Teradata's massively parallel (MPP) architecture, work is distributed across AMPs (Access Module Processors), and a query only completes once every participating AMP finishes its portion — so overall response time is bounded by the slowest AMP involved, not the fastest, the sum, or the average. This is the well-known "skew" problem in Teradata: if data or processing is unevenly distributed, one overloaded AMP becomes the bottleneck for the whole query regardless of how fast the others finish.
