• create a topic:
  

  aws --endpoint-url http://localhost:8000 sns create-topic --name=mytopic  --attributes='{"push-endpoint": "amqp://localhost", "amqp-ack-level": "broker",  "persistent": "true", "amqp-exchange": "topic_logs"}'
  

• create a bucket
  

  aws --endpoint-url http://localhost:8000 s3 mb s3://bobo
  

• create 2 notifications on that bucket:
  

  aws --region=default --endpoint-url http://localhost:8000 s3api put-bucket-notification-configuration --bucket bobo --notification-configuration='{"TopicConfigurations": [{"Id": "bobo_notif1", "TopicArn": "arn:aws:sns:default::mytopic", "Events": []}]}'
  aws --region=default --endpoint-url http://localhost:8000 s3api put-bucket-notification-configuration --bucket bobo --notification-configuration='{"TopicConfigurations": [{"Id": "bobo_notif2", "TopicArn": "arn:aws:sns:default::mytopic", "Events": []}]}'
  

• check which system object were created:
  

  bin/rados -p default.rgw.log ls | grep pubsub
  

• make sure that the notifications are created:
  

  aws --region=default --endpoint-url http://localhost:8000 s3api get-bucket-notification-configuration --bucket bobo
  

• delete the notifications from the bucket:
  

  aws --region=default --endpoint-url http://localhost:8000 s3api delete-bucket-notification-configuration --bucket bobo
  

• verify that the notifications are deleted:
  

  aws --region=default --endpoint-url http://localhost:8000 s3api get-bucket-notification-configuration --bucket bobo
  

• check for system objects again. we expect to see only "pubsub.", however we see:
  

  pubsub.
  pubsub..bucket.bobo/0b7b316e-a5e6-4bfd-aa6d-258ddf8fe2c3.4137.1
  

• removing the bucket did not delete the object either

when there are many buckets with notifications the fact that these objects are not deleted can create an issue
