This topic describes how Simple Message Queue (SMQ, formerly MNS) processes a queue that has not been used for a long period of time.
If your Alibaba Cloud account has sufficient balance and you have permissions to use SMQ, SMQ does not delete invisible queues or topics. However, if the permissions to use SMQ are revoked from your Alibaba Cloud account due to reasons such as overdue payments, SMQ deletes all queues and topics within your Alibaba Cloud account.
