### Backend VL (Velox) ### Bug description Velox only supports count() / count(T) for window functions. Spark's `count(c1, c2, ...)` variant must be rewritten into `count(if(or(isnull(c1),isnull(c2), ...), null, 1))` so the `WindowExec` can still be offloaded, which has already be handled in `AggregateExec` ### Gluten version main branch ### Spark version None ### Spark configurations _No response_ ### System information _No response_ ### Relevant logs ```bash ``` -- This is an automated message from the Apache Git Service.
