This test was wrong, actually we can push down nondeterministic filter through project, as long as the project list is all deterministic.

Could you move this case above case filter @ Filter(condition, w: Window)?
Based on the comment you add above, it becomes easier to follow by the readers.

…ith non-deterministic expressions ## What changes were proposed in this pull request? Similar to `Project`, when `Aggregate` has non-deterministic expressions, we should not push predicate down through it, as it will change the number of input rows and thus change the evaluation result of non-deterministic expressions in `Aggregate`. ## How was this patch tested? new regression test Author: Wenchen Fan <[email protected]> Closes #17562 from cloud-fan/filter. (cherry picked from commit 7577e9c) Signed-off-by: Xiao Li <[email protected]>

Similar to
Project, whenAggregatehas non-deterministic expressions, we should not push predicate down through it, as it will change the number of input rows and thus change the evaluation result of non-deterministic expressions inAggregate.How was this patch tested?
