The new `filterMv` function in #17659 provides a workaround for this. When GROUP BY explodes MV values into separate groups, you can use `filterMv` to control exactly which elements participate in grouping: ```sql -- Instead of GROUP BY array_col which explodes all elements: SELECT filterMv(array_col, 'v = 1') AS filtered, COUNT(foo) FROM myTable GROUP BY filterMv(array_col, 'v = 1') ``` This filters the MV array at the element level *before* grouping, so only matching elements appear as group keys. `filterMv` supports `=`, `!=`, `>`, `>=`, `<`, `<=`, `IN`, `NOT IN`, `BETWEEN`, `REGEXP_LIKE`, and compound predicates with `AND`/`OR`/`NOT`. -- This is an automated message from the Apache Git Service.
