### Is your feature request related to a problem or challenge? The `corr` function is used in the h20 benchmark and is quite slow. https://github.com/apache/datafusion/blob/main/datafusion/functions-aggregate/src/correlation.rs It would be great to make it faster so our performance in the H2o benchmark improves ### Describe the solution you'd like See details on https://github.com/apache/datafusion/issues/13548 1. Add a benchmark for `corr` function 2. Improve performance of `corr` function (likely by implementing `GroupsAccumulator`) ### Describe alternatives you've considered _No response_ ### Additional context Used here in @MrPower's benchmark: https://github.com/MrPowers/mrpowers-benchmarks/blob/0b586a0657d7f6cfd55d89508e15b95e79bd4010/benchmarks/datafusion_h2o_groupby_queries.py#L37 -- This is an automated message from the Apache Git Service.
