### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

# Allow the root user to perform any action.
allow {
 input.owner == true
}

# All other users may do anything other than call PutObject

				wg.Wait()
				// Flatten for upstream, but save full state.
				var root dataUsageEntry
				if r := cache.root(); r != nil {
					root = cache.flatten(*r)
				}
				select {
				case <-ctx.Done():
					return
				case bucketResults <- dataUsageEntryInfo{
					Name:   cache.Info.Name,
					Parent: dataUsageRoot,
					Entry:  root,
				}:
				}

				// Save cache
