> If your consumer acknowledge messages, you can just estimate the maximum size of disk space by write_quorum_size * the size of the retention policy. Thank you for your answer. https://pulsar.apache.org/docs/en/cookbooks-retention-expiry/ > The retention policy settings do not affect unacknowledged messages on topics with subscriptions Does the above document mean that while the messages in the consumer's backlog are not deleted by the retention policy settings, but all messages including acknowledged and unacknowledged are included to calculate the size limit of the retention policy? If so, it make sense. I can easily manage maximum disk space only by retention policy and write_quorum_size. I thought that the retention policy and backlog quota would control the size limit of acknowledged messages and unacknowledged messages independently. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
