When are messages on the azurue service bus phyically deleted?

Question

While messages are only received once from the service bus, is there a phyiscal deletion of the read messages in the quee?
For example a "garbage collect" after x minutes or the space is reused when new messages are coming in.

I wouldn't expect that messages that are marked as read are immediately physically deleted , but is there a mechanism to be shure, that read messages are erased from the cloud? (some believe the cloud is bad, bare metal is good).

@Anonymous In the azure service bus as soon as you have marked the message as Completed the message will be marked as deleted from our end.
The messages may take a few milliseconds/seconds to be completely removed. If you have concerned that the message is not deleted completely from your entities then you can rest assured that it won’t happen.
