> Key: ARROW-16457
> URL: https://issues.apache.org/jira/browse/ARROW-16457
> Project: Apache Arrow
> Issue Type: Improvement

> Reporter: Antoine Pitrou
> Priority: Major
> Fix For: 9.0.0

>
> ARROW-10675 added support for AWS S3 Web identity credentials on the C++
> side. We should bind that functionality on the Python side.
> To avoid proliferation of authentication arguments to the {{S3FileSystem}}
> constructor, some of which mutually exclusive (but not all), we should
> probably add instead a more flexible {{auth}} argument that could represent
> to different authentication kinds.
> There is a bit of API design necessary. IMHO it's probably best if the
> {{auth}} argument is a dedicated {{S3Auth}} object with several constructors,
> but perhaps we can instead admit some kind of dict?
