indices_cache_file_names (`[Dict[str, str]]`, *optional*, defaults to `None`):
                Provide the name of a path for the cache file. It is used to store the
                indices mapping instead of the automatically generated cache file name.
                You have to provide one `cache_file_name` per dataset in the dataset dictionary.
            writer_batch_size (`int`, defaults to `1000`):
                Number of rows per write operation for the cache file writer.
                Higher value gives smaller cache files, lower value consume less temporary memory.
