class pyarrow.flight.FlightCallOptions(timeout=None, write_options=None, headers=None)

Bases: pyarrow.lib._Weakrefable

RPC-layer options for a Flight call.


Create call options.

  • timeout (float, None) – A timeout for the call, in seconds. None means that the timeout defaults to an implementation-specific value.

  • write_options (pyarrow.ipc.IpcWriteOptions, optional) – IPC write options. The default options can be controlled by environment variables (see pyarrow.ipc).

  • headers (List[Tuple[str, str]], optional) – A list of arbitrary headers as key, value tuples
