> So essentially we are going to have operators that require a `KeyPartitioned` distirbution with two options to achieve this. Repartition via `Hash` or repartition via `Range`. [...] Should we only repartition to range if it is to a superset of the current range partitioning (example: data partitioned on `day` -> repartition to `hour`)? Filters involving ranges (at least BETWEEN, <=, <, >, >=, involving literals at first, but possibly we can do something smart for columns and more complex expressions too) could benefit from range partitioning too, as it would allow partition pruning of entire partitions without evaluation. -- This is an automated message from the Apache Git Service.
