Features

  • time (Stream Processor)

    The PriorityStreamProcessor keeps track of the priority of events in a stream. When an event with a new unique key arrives, PriorityStreamProcessor checks the priority and if the priority is 0 the event is sent out without being stored internally. If the event has a priority greater than 0, it is stored in the stream processor and the current priority is injected into that event. When an event with an existing priority key arrives, it is stored as the recent event and the priority is increased by the priority of the received event, and the priorityKey and the currentPriority is injected into the event. After every given timeout, priority of every event is reduced by 1 and the updated priority is sent out with the last known attributes of those events. It continues until their priorities reduce to 0.
