candlerb commented on issue #5542: [Issue 5541] cpp and python API: consumer and reader seek URL: https://github.com/apache/pulsar/pull/5542#issuecomment-549122409 Regarding the main documentation site: I can't see the ability to seek described anywhere at the moment. 1. Should the [clients](https://pulsar.apache.org/docs/en/next/concepts-clients/) page mention that consumers and readers can `seek()`? 2. It's not immediately obvious to me what happens when a consumer does a seek on a long-lived topic, especially if there are multiple consumers sharing the subscription. Are all messages prior to the seek point marked as "acknowledged", and all messages from the seek point onwards marked as "unacknowledged"? This relates to [message retention and expiry](https://pulsar.apache.org/docs/en/next/concepts-messaging/#message-retention-and-expiry).
