Spark has no GROUPS frame unit: the parser grammar only accepts `RANGE` and `ROWS`, and the catalyst jars for 4.1.3 and 4.2.0 define `RowFrame` and `RangeFrame` with no `GroupsFrame` class, so no Spark plan can reach the `WindowFrameUnits::Groups` guard in native/core/src/execution/planner.rs. There is nothing for Comet to fall back from or add here until Spark itself grows the feature. Suggest closing. -- This is an automated message from the Apache Git Service.
