Would like to note that the DataFusion performance really starts to lag when the dataset size grows. Take a look at this query: `select id2, id4, power(corr(v1, v2), 2) as r2 from x group by id2, id4`. When the dataset is 10 million rows, then Polars takes 3 seconds and DataFusion takes 3.6 seconds, so pretty similar. When the dataset is 100 million rows, then Polars takes 126 seconds and DataFusion takes 2,100 seconds. -- This is an automated message from the Apache Git Service.
