    Description

      As SupportsReportPartitioning allows implementations of Scan provide Spark with information about the exiting partitioning of data read by a DataSourceV2, a similar mix in interface SupportsReportOrdering should provide order information.

      This prevents Spark from sorting data if they already exhibit a certain order provided by the source.
