Hi Jerry, I don't recall there being a strong reason for not including this in the first implementation. I expect it wasn't included because it is generally expected that default credentials [1] would serve the very common cases, and that most other cases would involve service accounts. If a use-case isn't covered I think adding it would be desirable.
Thanks, Micah [1] https://github.com/apache/arrow/blob/6b66c842eefec520d391203d205cd91d1ca0dd65/cpp/src/arrow/filesystem/gcsfs.h#L107 On Thu, Mar 13, 2025 at 11:42 AM Jerry Adair <jerry.ad...@sas.com.invalid> wrote: > Hi, > > Currently, I use the Arrow filesystem library to establish an object that > I then use to connect to a GCS server.
