"A dynamic overload detector offers more flexibility and improves hardware efficiency, especially in a complex service such as ours. With QALM, we implemented an overload detector inspired by the CoDel algorithm. A lightweight request buffer (implemented by goroutine and channels) is added for each enabled endpoint to monitor the latency between when requests are received from the caller and processing begins in the handler. Each queue monitors the minimum latency within a sliding time window, triggering an overload condition if latency goes over a configured threshold." - https://eng.uber.com/qalm/
