### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Motivation broker.conf ``` brokerServiceCompactionMonitorIntervalInSeconds=60 brokerServiceCompactionThresholdInBytes=0 subscriptionExpirationTimeMinutes=4320 subscriptionExpiryCheckIntervalInMinutes=5 allowAutoSubscriptionCreation=false ``` We are seeing logs below in our environment: ``` 2023-01-04T12:19:56.098Z [bookkeeper-ml-scheduler-OrderedScheduler-0-0] INFO org.apache.pulsar.broker.service.persistent.PersistentTopic - [persistent://data/relation/__change_events-partition-2][__compaction] The subscription was deleted due to expiration 2023-01-05T17:04:51.665Z [pulsar-io-4-5] WARN org.apache.pulsar.broker.service.ServerCnx - [/172.30.92.38:43186][persistent://z/job/__change_events-partition-0][__compaction] Failed to create consumer: consumerId=16444, Subscription does not exist 2023-01-05T17:04:51.665Z [pulsar-io-4-4] WARN org.apache.pulsar.client.impl.ConsumerImpl - [persistent://z/job/__change_events-partition-0][__compaction] Failed to subscribe to topic on 172.30.92.38/172.30.92.38:6650 ``` ### Problems 1. `__compaction` subscription was deleted by sub expiration mechanism 2. `__compaction` subscription cannot re-create cause we disabled `allowAutoSubscriptionCreation` ### Solution 1. Skip `__compaction` subscription in subscription cleanup process 2. Allow `__compaction` sub auto creation even if `allowAutoSubscriptionCreation=false` ### Alternatives _No response_ ### Anything else? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
