### Is your feature request related to a problem or challenge? When working with lexicographical orderings that share a common prefix column A, we currently don't leverage the fact that satisfying the prefix ordering implies satisfaction of all derived orderings. This leads to redundant sort operations in the physical plan. ### Describe the solution you'd like Introduce Constraints or similar concepts in the physical planner to recognize and optimize cases where multiple lexicographical orderings share common prefixes. For instance, if we have a global ordering on column A (with unique elements), we should recognize that orderings like [prefix..., A, B, C] and [prefix..., A, D] are automatically satisfied when [prefix..., A] is satisfied. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
