Object ACL is an object-level (not bucket level) permission control mechanism. There are currently three levels of access rights: private, public-read, and public-read-write.

"Private" indicates that an object is a private resource, that is, only the owner of the object has read and write permissions on the object, and other users can read but have no permission to modify or delete the object.

If the permissions of an object are not set, the permissions of the object are inherited from the bucket.

You can set the ACL associated with an object by examining the X-OSS-Object-ACL header in the HEAD request, when making the PutObjectACL API call.

Event Notifications can cross regions.

Message Service provides synchronous notifications to ensure the consistency between the message acknowledgment and event processing.

The event notification message is retained within the valid time. When you fail to receive an event message, the event notification message is retried based on the specified retry policy.

The consumer type of the event notification message can be HTTP Server, Queue, or Topic.
