to_arrow_ipc

to_arrow_ipc()

to_arrow_ipc(input_path: str, output_path: str, batch_size: typing.SupportsInt | None = None, num_threads: typing.SupportsInt | None = None, guess_integer: bool = True, trim_ws: bool = True, escape_backslash: bool = False, decimal_mark: str = ‘.’, skip: typing.SupportsInt = 0) -> None

Convert a CSV file to Arrow IPC format.

NOTE: This function is not yet implemented. It will raise an error explaining that Arrow IPC output requires FlatBuffers integration. Use to_parquet() for columnar output instead.
