   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   in order to support order by and partition by within window functions in DataFusion, we'll need to find out partition points on already sorted columns (lexicographically)
   
   
   
   **Describe the solution you'd like**
   Add a partition kernel that takes a stream of already sorted records and returns Ranges that map to distinct values of the SortKey
   
   ** Context **
   @Jimexist  is working on this feature and I wanted to capture it in a ticket
