Is there a way to update object attributes without fetching all bytes?

[Eric100210]

Hello, I'm looking for a way to update the attributes of a S3 object without downloading and re-uploading its content.

Currently the only way I found is:

result = store.get(path)
store.put(path, result.bytes, attributes=new_attributes)

I don't believe there's an upstream API to do this. If you search for Attributes in the upstream docs, the only APIs to set Attributes are in PutOptions, PutMultipartOptions, and in BufWriter.

See apache/arrow-rs-object-store#94. I don't immediately see another upstream issue for modifying Attributes. You may want to create one.
