Special privileges are additional permissions that allow a user to manage or access certain aspects of the Registry. The special privileges are:
Can manage buckets - Allow a user to manage all buckets in the registry, as well as provide the user access to all buckets from a connected system (e.g., NiFi).
Can manage users - Allow a user to manage all registry users and groups.
Can manage policies - Allow a user to grant all registry users read, write, and delete permission to a bucket.
Can proxy user requests - Allow a connected system (e.g., NiFi) to process requests of authorized users of that system. For example, if dev and prod NiFi clusters are connected to the same NiFi Registry instance, privileges can be set to allow the dev NiFi cluster to only update versioned flows while limiting the prod NiFi to only download flows.
