gene-bordegaray opened a new issue, #22397:
URL: https://github.com/apache/datafusion/issues/22397
### Is your feature request related to a problem or challenge?
`RepartitionExec` rejects `Partitioning::Range`, so we cannot repartition
rows into this layout.
### Describe the solution you'd like
Add support for range repartitioning in `RepartitionExec`.
The implementation should:
- Route rows to output partitions via range partitioning
- Support single-key and compound-key range partitioning
- Keep hash repartitioning as a fallback when range repartitioning is not
requested / be applied.
### Describe alternatives you've considered
Continue to use hash repartitioning as the only repartitioning. It is a good
fallback, but it doesn't preserve / create range partitioning when a plan would
benefit from a range-partitioned layout.
### Additional context
Context: #21992
Current code locations:
- `datafusion/physical-plan/src/repartition/mod.rs`
- range execution is not implemented in `BatchPartitioner`
- changing partition counts with range partitioning is not implemented
- execution path rejects range partitioning
