Abstract: A system performs incremental updates to an event data store based on hydration and stateful validation of events to allow efficient generation of reports based on event data. The system stores data describing events received in a raw event data store. An event represents user interactions associated with a content item. Each event is classified as a thin event, or a thick event based on the type of user interaction associated with the event. The system monitors changes to the raw event data store, for example, using a listener process. The system stores event data in a hydrated event data store that includes records, each record storing information describing thin events associated with a thick event along with additional attributes describing each thin event.
