Hi everyone, I'd like to open a discussion on an extension to the REST Catalog spec to enable file-level access delegation during scan planning. Today, delegated access is table-scoped, which can force over-provisioning or table fragmentation when consumers should only see a subset of partitions or records. This proposal adds a path using pre-signed URLs to make partition-scoped sharing practical in the REST Catalog model.
Here is my proposal: https://s.apache.org/n16st I look forward to hearing your thoughts. Relevant discussion: - https://lists.apache.org/thread/ko9kp0gvzhx85n7cvoxqnpw4vwnhmdg6 Best, William
