Weston Pace commented on ARROW-12681:
-------------------------------------
I agree it is odd and it makes it more difficult to duck type generic
collections of readers. It would be nice if users could avoid things like:
{code: python}
for reader in readers:
if reader instance of ...
else:
{code}
> [Python] Expose IpcReadOptions to ipc facility
> ----------------------------------------------

> Key: ARROW-12681
> URL: https://issues.apache.org/jira/browse/ARROW-12681
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Francois Saint-Jacques
> Priority: Minor
>
> I would like to be able to read only a subset of columns from a given IPC
> file. To do this, we need to expose the EXPERIMENTAL (is it still?)
> IpcReaderOptions.include_fields option. The reason is that the file is on a
> remote storage and can't mmap thus I want to minimize network transfer.
> I do not know the best way to "pythonize" IpcReaderOptions and would need
> help on this.
