Railgun: managing large streaming windows under MAD requirements

Summary: Railgun: elastic distributed streaming with true long-horizon sliding windows under MAD, avoiding fixed-window shortcuts. Outperforms Flink on latency; scales near-linearly to 1M events/s with ms latency and memory independent of window size. (summarized by gpt-5-nano on Feb 09 2026)
