@kumarUjjawal Thank you. I’m currently working on splitting out the partial and final aggregation paths. There are a few related paths as well, and I’m still figuring out the best way to organize the refactor. - https://github.com/apache/datafusion/pull/22729 One orthogonal path you could try is the case where the input is already ordered by the grouping keys. Today, `GroupsHashAggregation` still performs regular hash aggregation there, with eager output for memory efficiency. That path may be worth specializing further for performance. -- This is an automated message from the Apache Git Service.
