### Is your feature request related to a problem or challenge? Grouped aggregation currently inserts a hash `RepartitionExec` when grouping by `date_bin` or `date_trunc` over a range-partitioned input, even when the existing partitioning keeps each group local to one input partition. #25344 establishes how functions expose that they support range-partitioning analysis, but the partition-satisfaction and aggregation-planning logic must use that information before the unnecessary repartition can be removed. ### Describe the solution you'd like Use the range-transformation information exposed by #25344 to determine when the existing range partitioning keeps each group local to one input partition. When that guarantee holds, allow grouped aggregation to use the existing range partitioning instead of inserting a hash `RepartitionExec`. Grouped aggregation will be the first consumer, but the underlying range information should remain usable by other operators in future work. ### Additional context Part of #23569. Depends on #25344. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
