Some embodiments provide a system that includes a set of event publishers configured to publish events occurring on the event publishers. The system also includes a uniform event framework configured to receive, from an event publisher in the set of event publishers, an event notification indicating an event occurred on the event publisher and generate an event structure based on the event notification. The system further includes an event bus configured to receive the event notification from the uniform event framework and send the event structure to a set of event subscribers for consumption of the event structure. Each event publisher in the set of event publishers is further configured to receive different callbacks from different event subscribers in the set of event subscribers for different sets of data associated with the event.
