Abstract
A method for event processing includes accepting for processing, as accepted events and according to a target rate limit, at least a subset of received events; associating respective ingested timestamps with the accepted events; associating respective processing completion timestamps with processed events of the accepted events; determining an average measured lag time using at least a subset of the respective processing completion timestamps and corresponding respective ingested timestamps; obtaining a throttled rate limit using a proportional-integral-derivative (PID) controller; and accepting subsequent events according to the throttled rate limit. The PID controller can be configured to use, as an input, an error value that is a difference between a target lag time and the average measured lag time. An integral part of the PID controller can be set to zero responsive to an accumulated average lag time being less than the target lag time.
