Abstract
Methods, systems, and computer-readable media are disclosed for time-based event processing using punctuation events. A particular method includes receiving a first event object comprising a first validity start time and a first validity end time, where the first validity end time is initially undefined. A punctuation object is received after the first event object. The punctuation event object has a punctuation timestamp indicating a time subsequent to the first validity start time. The punctuation event object indicates that event objects to be received at the computer system after the punctuation event object have validity start times later than the time indicated by the punctuation timestamp. The method includes setting the first validity end time to a value later than or equal to the time indicated by the punctuation timestamp.
