I'd like to work on this. Since the TopK dynamic filter is only a pruning hint, my plan is to make it conservative when the threshold of a floating-point sort key is ±0.0: use a non-strict bound for that column (e.g. `x <= 0.0` instead of `x < 0.0 OR (x = 0.0 AND ...)`), so `-0.0`/`0.0` rows are never filtered out and the heap's total ordering decides. I'll add a sqllogictest reproducing the multi-batch case from this issue. -- This is an automated message from the Apache Git Service.
