### Is your feature request related to a problem or challenge? @mustafasrepo and others have contributed to a sophisticated window function implementation in DataFusion like ```sql select x, lag(x, 1) OVER (partition by y, order by x) FROM foo ``` However, the user guide https://arrow.apache.org/datafusion/user-guide/sql/index.html does not appear to mention this ### Describe the solution you'd like 1. Note in the user guide that DataFusion supports window functions 2. Add a new page for WindowFunctions Note the docs (and instructions) are in https://github.com/apache/arrow-datafusion/tree/main/docs The list of window functions is the normal aggregate functions as well as https://docs.rs/datafusion-expr/24.0.0/datafusion_expr/window_function/enum.BuiltInWindowFunction.html https://docs.rs/datafusion-expr/24.0.0/datafusion_expr/window_function/enum.WindowFunction.html ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
