[GitHub] [pulsar] fxbing opened a new issue #4933: Backlog size calculation errors can result in unlimited messages being produced

fxbing opened a new issue #4933: Backlog size calculation errors can result in unlimited messages being produced 
URL: https://github.com/apache/pulsar/issues/4933
 
 
   **Describe the bug**
   Backlogs are sets of unacknowledged messages for a topic that have been stored by bookies even if not consumed. But in fact, if the topic has not been consumed, you can produce unlimited messages.
   https://github.com/apache/pulsar/blob/be7b24f9f8aa67b2235e523485249aef8d2a611a/managed-ledger/src/main/java/org/apache/bookkeeper/mledger/impl/ManagedLedgerImpl.java#L921-L926
   
   
   **To Reproduce**
   Set a limited BaclogQuotaSize to produce unlimited messages without consuming.
   
   **Expected behavior**
   Limited production message
