ABSTRACT:
In one embodiment, a system for distributed event processing includes a first event processor and a second event processor. The first event processor receives event data associated with an event stream. The second event processor receives a query associated with the event stream. A request to the first event processor is generated by the second event processor based on the query for a first portion of event data associated with the event stream. The second event processor receives the first portion of event data from the first event processor. The second event processor then generates an event based on the first portion of event data.
