I think we need emission rules beyond a size-based trigger for unbounded streams. Possible strategies include: 1. Time-based: Emit if no new input arrives within a configurable time interval. 2. Count-based: Emit after N consecutive polls that return no input, indicating the stream is idle. 3. Watermark/checkpoint barrier-based: Emit when a watermark or checkpoint barrier indicates that all relevant events have been observed, following event-time semantics. -- This is an automated message from the Apache Git Service.
