I'd like to echo a question that was asked earlier this year: If we do a global sort of a dataframe (with two columns: col_1, col_2) by (col_1, col_2/desc) and then dropDuplicates on col_1, will it retain the first row of each sorted group? i.e. Will it return the row with the greatest value of col_2 for each col_1 group?
Thanks, Allen
