> Currently we respond with CANCELLED only when hitting EOS. It seems a bit more robust to always respond with CANCELLED whenever query execution has terminated. That way, if the cancel RPC from the coordinator to a backend fails, the backend will still cancel if it can send status back to the coordinator later on.
