> According to the documentation ( https://arrow.apache.org/docs/python/generated/pyarrow.flight.FlightClient.html#pyarrow.flight.FlightClient.do_action ) I would expect to be able to invoke {{client.do_action}} and get back an iterator. While it seems that the function is in fact a generator itself.
> This makes a big difference because if it returns an iterator I expect to be able to do {{client.do_action(...)}} and just ignore the result if I don't care. But if it's a generator ignoring the results makes so that it actually doesn't get invoked at all and thus that the server won't do anything.
> It would make sense to make {{do_action}} return a generator instead of being a generator itself, that would keep backward compatibility and would avoid puzzled users that don't see their code being invoked when they do {{client.do_action(...)}}
