### Is your feature request related to a problem or challenge? The phase 1 PR for sort pushdown with inexact mode implementation: https://github.com/apache/datafusion/pull/19064 This ticket we will implement the phase 2: ```rust //! ## Current capabilities (Phase 1) //! //! - Reverse scan optimization: when required sort is the reverse of the data source's //! natural ordering, enable reverse scanning (reading row groups in reverse order) //! - Supports prefix matching: if data has ordering [A DESC, B ASC] and query needs //! [A ASC], reversing gives [A ASC, B DESC] which satisfies the requirement //! //! ## Future enhancements (Phase 2) //! //! - File reordering based on statistics //! - Return `Exact` when files are known to be perfectly sorted //! - Complete Sort elimination when ordering is guaranteed ``` ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
