Hi, @poorbarcode
Do you wanna make this configuration enabled by default in the future? if so, we can add the planning to the proposal. :)

That is a good suggestion, the next PIP will do these two things:

  • Provide a new config maxAckStatePersistentInBytes to instead managedLedgerMaxUnackedRangesToPersist, and deprecated managedLedgerMaxUnackedRangesToPersist. And set the default value of maxAckStatePersistentInBytes to 5m
  • Make this dispatcherPauseOnAckStatePersistentEnabled enabled by default

Hi @poorbarcode, do we have metrics to monitor this phenomenon for convenient monitoring and alerting?

Hi @poorbarcode, do we have metrics to monitor this phenomenon for convenient monitoring and alerting?

Only pulsar_subscription_unacked_messages is helpful for this case right now.

After the next PIP(see #21118), I will add a new metrics pulsar_subscription_metadata_size
