benbellick opened a new issue, #26448: URL: https://github.com/apache/datafusion/issues/26448
Allow grouped aggregation to reuse single-key timestamp range partitioning when an audited, timezone-less `date_trunc` expression keeps every group within one input partition. For example, hourly truncation over hour-aligned partitions can avoid the hash shuffle, while daily buckets crossing those partitions must retain it. Establish a default-deny function capability and check concrete split boundaries before accepting the locality proof. Unsafe or unknown cases must retain repartitioning. This aggregate-locality proof must not establish join-layout compatibility. This is an initial slice of #25344 and #25345 under #23569. `date_bin` and compound range-key support remain follow-up work, with compound keys tracked in #24644. -- This is an automated message from the Apache Git Service.
