Envoy control plane to data plane xDS v3: SotW omission versus Delta removed_resources semantics
Integration boundary The integration boundary between an xDS v3 control plane and Envoy data plane must reconcile two resource-removal mechanisms: state-of-the-world (SotW) streams signal deletion by omitting a resource from the full snapshot, while Delta streams carry explicit removed_resources entries. A control plane that serves some resource types via So
