Hi, The latest documentation <https://docs.ceph.com/en/latest/radosgw/s3-notification-compatibility/#supported-destination> says that: "pulling and acking of events stored in Ceph (as an internal destination)." is a valid source for s3 notifications. If i got it right, pull-based subscription was possible only with radosgw PubSub sync module, which was removed in reef release <https://docs.ceph.com/en/latest/releases/reef/#:~:text=The%20pubsub%20functionality%20for%20storing,notifications%2C%20and%20acking%20the%20notifications> . Suggested changes: Currently, we support: HTTP/S, Kafka and AMQP. And also support pulling and acking of events stored in Ceph (as an internal destination).
