This API is used to delete multiple objects from a bucket. You can delete up to 1,000 objects using a single request. COS supports two modes for the response: Verbose and Quiet.
To make this request, you need to have permission to write to the bucket.
If versioning is enabled, you can specify the version ID of each object in this API request to permanently delete the specified version or delete marker of the object. If the version ID is not specified, COS will create a delete marker as the latest version of the object.
When the delete operation creates or deletes a delete marker for an object, the response returns both elements <DeleteMarker>true</DeleteMarker> and <DeleteMarkerVersionId>.
When the delete operation permanently deletes a specified version (including that of a delete marker) from an object, the response returns the element <VersionId>.
