> Thanks @mustafasrepo but just for curiosity, how the test becomes deterministic if only test result has changed? 🤔 no extra sorting or code change In this PR, I have changed source table such that timestamp values are unique. Since each group consists of distinct rows, `MIN(timestamp)`, or `MAX(timestamp)` would produce unique results after aggregation (e.g different for each row). Hence when ordering `ORDER BY MIN(timestamp)` is applied there is no tie break (where there may be more than 1 true result). -- This is an automated message from the Apache Git Service.
