I have some thoughts about why `SinglePartitioned` is faster than `Partial + FinalPartitioned` in high cardinality case. It may be as same as the `skip partial optimization` merged recently? They all skipped the partial making no benefit in the `high cardinality + large amount distinct values` case? -- This is an automated message from the Apache Git Service.
