Hmm... this looks quite empty, are you planning to add support for GcsOptions? Or are people expected to instantiate these filesystems using an URI?

I'll add do it eventually but it's usable without this by #12763 (or #12932).

Or are people expected to instantiate these filesystems using an URI?

Yes. We can load data by Arrow::Table.load("gcs://bucket/a.arrow") with this. https://github.com/apache/arrow/blob/master/ruby/red-arrow-dataset/lib/arrow-dataset/arrow-table-loadable.rb#L38 instantiates GArrowGCSFileSystem and it's used to load data.

[pitrou]

Ok, so should there be a dedicated test?

[kou]

We can't implement now because gcs://bucket/a.arrow doesn't work without #12763.

[pitrou]

Ah, fair enough :-)
