-----------------------------------
Labels: pull-request-available (was: )
> [Python] FlightClient.do_action is a generator instead of returning one.
> ------------------------------------------------------------------------
>
> Key: ARROW-14255
> URL: https://issues.apache.org/jira/browse/ARROW-14255
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 5.0.0
> Reporter: Alessandro Molina
> Assignee: Alessandro Molina
> Priority: Major
> Labels: pull-request-available
> Fix For: 6.0.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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(...)}}
