js8544 opened a new issue, #37059: URL: https://github.com/apache/arrow/issues/37059
### Describe the enhancement requested Rolling functions compute statistics over a fixed length sliding window. They include: - rolling_sum - rolling_sum_checked - rolling_prod - rolling_prod_checked - rolling_min - rolling_max - rolling_mean I also plan to add rolling_median. It requires a sophisticated data structure (either [skiplist](https://en.wikipedia.org/wiki/Skip_list) or [order statistic tree](https://en.wikipedia.org/wiki/Order_statistic_tree)) so I'll do it in another issue. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
