MarvinCai commented on PR #17320:
URL: https://github.com/apache/pulsar/pull/17320#issuecomment-1230421582

   According to the `BacklogQuotaManager`'s logic here: https://github.com/apache/pulsar/blob/master/pulsar-broker/src/main/java/org/apache/pulsar/broker/service/BacklogQuotaManager.java#L104-L107
   I think the behavior should be broker disconnect producer when it detect backlog quota exceeded, and producer will get `ProducerBlockedQuotaExceededError` which is retryable, so it'll keep reconnecting till backlog is cleared: https://github.com/apache/pulsar/blob/master/pulsar-client/src/main/java/org/apache/pulsar/client/impl/ProducerImpl.java#L1759-L1762
   So no data will be send to broker in such base and producer is hold the data till backlog is cleared.
   Will let Jiwei confirm.
