The important thing to keep in mind is that the `sub` key should have a unique identifier across the entire application, and it should be a string.

## Check it

Run the server and go to the docs: <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

You'll see the user interface like:

  // +optional
  optional k8s.io.apimachinery.pkg.apis.meta.v1.Time lastScaleTime = 2;

  // currentReplicas is current number of replicas of pods managed by this autoscaler,
  // as last seen by the autoscaler.
  optional int32 currentReplicas = 3;

  // desiredReplicas is the desired number of replicas of pods managed by this autoscaler,
  // as last calculated by the autoscaler.

Replication status can be seen in the metadata on the source and destination objects. On the source side, the `X-Amz-Replication-Status` changes from `PENDING` to `COMPLETED` or `FAILED` after replication attempt either succeeded or failed respectively. On the destination side,...
