# QueueEmptyingThreshold

CFS generates an event when the import queue becomes full, becomes empty, or the queue size passes certain thresholds.

This parameter specifies the threshold at which a `QueueEmptying` event is triggered. When the number of documents in the queue falls below this proportion of the total queue size, the event is triggered.

The value of this parameter must be less than the value of QueueFillingThreshold.
