Retrieve only object metadata (no object data) from users' Cloud Storage objects while maximizing performance. How should you retrieve the metadata?

To retrieve only object metadata and maximize performance, use the fields request parameter. This parameter allows you to specify exactly which fields of the object's metadata you want to retrieve, significantly reducing the amount of data transferred and processed. For example, you could request name,size,contentType. The patch method is used to update parts of an existing object's metadata or data, not to retrieve it. The compose method combines multiple objects into a new single object. The copy method creates a duplicate of an existing object. These methods do not primarily serve the purpose of efficiently retrieving only metadata.
