### Notes This implementation takes inspiration from the previous [`[#22996](https://github.com/apache/datafusion/pull/22996)`](https://github.com/apache/datafusion/pull/22996) implementation and its review discussion, particularly around handling the cases that were called out there. This PR currently covers: * `ORDER BY` within `map_agg` * `GROUP BY` usage * First-occurrence-wins semantics for duplicate keys * Tests covering the above behavior For ordered aggregation, duplicate keys are de-duplicated after applying the aggregate's `ORDER BY`, so the first occurrence in the resulting order is retained. -- This is an automated message from the Apache Git Service.
