Hi, If you're not using Beam SQL's HOP windowing functions, you're not affected.
*The problem* Calcite defines <https://calcite.apache.org/docs/reference.html#grouped-window-functions> HOP windowing function like this: - HOP(timestamp_field, frequency_interval, window_size) Beam SQL implemented incorrectly, swapping frequency_interval and window_size: - HOP(timestamp_field, window_size, frequency_interval) *The fix* *The commit containing the fix swapping the parameters match Calcite doc has been just pushed, see BEAM-3610 <https://issues.apache.org/jira/browse/BEAM-3610>.* Regards, Anton
