Build explicit opt-in adaptive global-window selection on the shared ordering stack. The default remains receiver sorting; cold, failed or incomplete evidence falls back and explicit true/false never train AUTO. Try `SET useMultistageEngine=true; SET windowSortOnSender='auto'; SELECT SUM(v) OVER (ORDER BY ts) FROM myTable;`; `false` disables it and `true` requests sender sorting. The current heuristic targets four senders and at least 400k rows. 1059 focused tests including sample-cleanup regressions and scoped style/license checks pass. Parent: https://github.com/apache/pinot/pull/19711. Keep draft until fresh controlled benchmarks and remote CI establish the tradeoffs. -- This is an automated message from the Apache Git Service.
