    • withIgnoreNullKeys

      public GroupByOptions.Builder withIgnoreNullKeys(boolean ignoreNullKeys)
      If true, the cudf groupby will ignore grouping keys that are null. The default value is false, so a null in the grouping column will produce a group.

    • withKeysSorted

      public GroupByOptions.Builder withKeysSorted(boolean keysSorted)
      Indicates whether rows in `keys` are already sorted. The default value is false. If the `keys` are already sorted, better performance may be achieved by passing `keysSorted == true` and indicating the ascending/descending order of each column and null order by calling `withKeysDescending` and `withKeysNullSmallest`, respectively.

    • withKeysDescending

      public GroupByOptions.Builder withKeysDescending(boolean... keysDescending)
      If `keysSorted == true`, indicates whether each column is ascending/descending. If empty or null, assumes all columns are ascending. Ignored if `keysSorted == false`.

    • withKeysNullSmallest

      public GroupByOptions.Builder withKeysNullSmallest(boolean... keysNullSmallest)
      If `keysSorted == true`, indicates the ordering of null values in each column. If empty or null, assumes all columns use 'null smallest'. Ignored if `keysSorted == false`.
