daft.DataFrame.sort#

DataFrame.sort(by: Union[daft.expressions.Expression, str, list[Union[daft.expressions.Expression, str]]], desc: bool | list[bool] = False) → daft.dataframe.dataframe.DataFrame[source]#

Sorts DataFrame globally

Example

>>> sorted_df = df.sort(col('x') + col('y'))
>>> sorted_df = df.sort([col('x'), col('y')], desc=[False, True])
>>> sorted_df = df.sort(['z', col('x'), col('y')], desc=[True, False, True])

Note

  • Since this a global sort, this requires an expensive repartition which can be quite slow.

  • Supports multicolumn sorts and can have unique descending flag per column.

Parameters

  • column (Union[ColumnInputType, List[ColumnInputType]]) – column to sort by. Can be str or expression as well as a list of either.

  • desc (Union[bool, List[bool]), optional) – Sort by descending order. Defaults to False.

Returns

Sorted DataFrame.

Return type
