freakyzoidberg opened a new pull request, #19853:
URL: https://github.com/apache/datafusion/pull/19853
## Summary
- Fixes incorrect results from ROLLUP/CUBE/GROUPING SETS queries when
using multiple partitions
- The subset satisfaction optimization was incorrectly allowing hash
partitioning on fewer columns to satisfy requirements that include
`__grouping_id`
- This caused partial aggregates from different partitions to be finalized
independently, producing duplicate grand totals
Closes #19849
