**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** As https://github.com/apache/arrow-datafusion/issues/361 all feature has been done in datafusion. We can bring window function in ballista ✌️ I have implement a simple version in my repo. But we need do some change in datafusion. - [ ] https://github.com/apache/arrow-datafusion/issues/4479 - [ ] https://github.com/apache/arrow-datafusion/issues/4480 **Describe the solution you'd like** After we use the related version datafusion, will implement some window function `Physical plan` encode and decode features. I have checked with datafusion, If the window function `PARTITION BY` and `ORDER BY`, the physical planner of datafusion has helped to add `repation` and `sort`. So we no need to deal `window_func` in `plan_query_stages_internal`. **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. **Additional context** Add any other context or screenshots about the feature request here. -- This is an automated message from the Apache Git Service.
