@sunchao here is the `RangePartitioning`. Tests show that data sources that report this partitioning avoid shuffle and sorting for supported right transformations. The `RangePartitioning` is derived from `KeyGroupedPartitioning`, because it as well partitions by the sort keys, while in addition the keys are sorted. Do you agree adding `rangePartitioning` to `DataSourceV2ScanRelation` and `DataSourceV2ScanExecBase` is the right thing, or should those `SortOrder` expressions be used as `keyGroupedPartitioning` instead and taken by `DataSourceV2Strategy` from there? -- This is an automated message from the Apache Git Service.
