Abstract

An event management service (EMS) operating in a distributed computing environment includes a queueing mechanism for controlling passage of events through an event channel when multiple event consumers cannot consume events being generated by one or more event suppliers as the events are being generated. The queueing mechanism includes a number of queues: an input queue that receives queue elements for each event that reaches the service, an active queue that receives queue elements for each event that any event consumer has registered to receive, and a consumer queue for each event consumer registered to receive any event. A multi-threaded process control routine processes the queue elements to control passage of the events to the event consumers.
