How are late events handled in RisingWave in relation to windowing?
RisingWave's materialized views are undateable. There's no 'late events' and every event will update the materialized view immediately. However, RisingWave does support watermark and emit-on-window-close semantics like Flink, which can produce append-only output stream.
