Use Aliyun OSS as storage backend

[Veiasai]

Description

Though I think OSS is compatible with AWS S3. However, I tried that in python deltalake and encountered some auth issues.

I wonder how could I turn on verbose logging?

(by the way, aws-cli works well after I configure endpoint/region/credentials. I did same change in deltalake storage_options)

hmm it doesn't show the raw http request.

You can use deltalake python package with aliyun oss by setting following environment variables, (replace region with your bucket region. e.g. cn-beijing):

export AWS_ACCESS_KEY_ID=<YOU FILL IT>
export AWS_SECRET_ACCESS_KEY=<YOU FILL IT>
export AWS_ENDPOINT_URL=https://<YOU_BUCKET>.oss-<region>.aliyuncs.com
export AWS_VIRTUAL_HOSTED_STYLE_REQUEST=true
export AWS_COPY_IF_NOT_EXISTS=header-with-status:x-oss-forbid-overwrite:true:409
export AWS_REGION=<region> # like cn-beijing

If you want to use HTTP and gain some extra performance

export AWS_ALLOW_HTTP=1
export AWS_ENDPOINT_URL=http://<YOU_BUCKET>.oss-<region>.aliyuncs.com

You can also use <YOU_BUCKET>.oss-<region>-internal.aliyuncs.com when in the same region.
