If no function is provided, defaults to an always True function: `lambda x: True`.
            with_indices (`bool`, defaults to `False`):
                Provide example indices to `function`. Note that in this case the signature of `function` should be `def function(example, idx): ...`.
            input_columns (`str` or `List[str]`, *optional*):
                The columns to be passed into `function` as
                positional arguments. If `None`, a dict mapping to all formatted columns is passed as one argument.
            batched (`bool`, defaults to `False`):
                Provide batch of examples to `function`.
            batch_size (`int`, *optional*, default `1000`):
                Number of examples per batch provided to `function` if `batched=True`.
            fn_kwargs (`Dict`, *optional*, default `None`):
                Keyword arguments to be passed to `function`.
