modin.pandas.DataFrame.set_backend

DataFrame.set_backend(backend: str, inplace: bool = False, *, switch_operation: Optional[str] = None) → Optional[Self][source]

Move the data in this DataFrame from its current backend to the given one.

Further operations on this DataFrame will use the new backend instead of the current one.

Parameters:

  • backend (str) – The name of the backend to set.

  • inplace (bool, default: False) – Whether to modify this DataFrame in place.

  • switch_operation (Optional[str], default: None) – The name of the operation that triggered the set_backend call. Internal argument used for displaying progress bar information.

Returns:

If inplace is False, returns a new instance of the DataFrame with the given backend. If inplace is True, returns None.

Return type:

DataFrame or None

Notes

This method will attempt to use the starting and new backend’s move_from or move_to methods if the backends implement them. Otherwise, it will

  1. convert the data in this DataFrame to a pandas DataFrame in this Python process

  2. load the data from pandas to the new backend.

Either step may be slow and/or memory-intensive, especially if this DataFrame’s data is large, or one or both of the backends do not store their data locally.
