> DataSourceV2 allows data sources to report existing partitioning of read data (org.apache.spark.sql.connector.read.partitioning). Currently, there is only KeyGroupedPartitioning and UnknownPartitioning. Data sources should be able to report global ordered data so that downstream operations can exploit this.
> The following is required for this to work:
> - Define RangePartitioning as a new implementation of Partitioning
> - Add Catalyst rules that handle this partitioning
> - Add a test source that reports ordering to proof that subsequent operations that require order do not invoke sorting the data.
