### Is your feature request related to a problem or challenge? This is my wishlist for improving high cardinality aggregates (ideally for the next blog post in a few months #11631 ) Together with the StringView work in https://github.com/apache/datafusion/issues/10918 that @XiangpengHao @a10y and others are working on, I think it would provide some very compelling overall speedups in ClickBench and TPCH queries ### Describe the solution you'd like Here is my wishlist: - [ ] https://github.com/apache/datafusion/issues/6937 (@korowa has a PR up for this one) - [ ] https://github.com/apache/datafusion/issues/7957 (I have a prototype and some ideas) - [ ] TBF: reuse the hashed values (working on filing this) ### Describe alternatives you've considered Do nothing and let DuckDB pass us by ;) ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
