Hi @Standing-Man, thank you for your contribution! However, I’d prefer to use cli::common::ObjectStoreConfig instead, so that we can keep all object storage configurations consistent.

You mean there already support Azblob, OSS, and GCS storage? If so, close this PR.

No, the data export and import CLI tools don't support these backends. You can refer to the metadata import CLI to see how cli::common::ObjectStoreConfig supports multiple backends.
