A request could be affected by multiple throttles:
  • A system throttle and a workload throttle
  • Multiple system throttles

In either case, a request cannot run until all applicable throttles are below their limit.

Carefully consider the impact of multiple throttles. A request may be in the delay queue longer than expected if it gets released from one throttle and is then delayed by another.

Tip: Teradata recommends that administrators keep throttles simple and avoid overlapping throttles. Overlapping throttles make it hard to analyze request behavior and tune throttle definitions.
