TomokoKomiyama edited a comment on issue #26192: [SPARK-29535][SQL] ADD some aggregate functions for Column in RelationalGroupedDataset.scala URL: https://github.com/apache/spark/pull/26192#issuecomment-545224163 @HyukjinKwon We can use `agg`, but I think it would be easier for users to use these aggregation functions with Colmun type in the similar way with String one. `df.groupBy("_c0").max("_c1")` `df.groupBy("_c0").max($"_c1")` Other functions can pass String type parameters because of the legacy reason and these will be removed someday, right? I think it would be better that these aggregation functions(max, min...) can pass Column type parameters for that time.
