Queries Per Second (QPS) Throttling is a feature offering DSPs the flexibility to control their bid stream and limit the amount of bid requests they receive from DT Exchange.

There are several reasons a DSP may want to use QPS throttling. Below are a few of the main use cases:

• Ensures QPS never exceeds the DSPs maximum server capacity limit
• Slowly ramps up traffic volume during new integration testing
• Avoids wasting server capacity in countries without high demand. Throttle QPS up or down on a need basis for specific countries
• Allocates supply volumes according to high-level inventory type (display vs. video)
