GitHub user jak78 added a comment to the discussion: Message unacknowlegment but i can not consume it
Hello @ThinhLe30, and welcome to the community! The behavior you're experiencing is due to the default setting of the initial subscription position as `Latest`. This setting means that the subscription will only deliver messages that are received after the subscription is created. To modify this behavior, you can opt for the `Earliest` option in [SubscriptionInitialPosition](https://pkg.go.dev/github.com/apache/pulsar-client-go/pulsar#SubscriptionInitialPosition) within the `ConsumerOptions` when creating the consumer. By selecting Earliest, the subscription will instead deliver the oldest messages that have not yet been consumed, starting from the earliest available. Feel free to try the following: ```go consumer, err := client.Subscribe(pulsar.ConsumerOptions{ Topic: "my-topic", SubscriptionName: "my-sub", Type: pulsar.Shared, SubscriptionInitialPosition: pulsar.Earliest, }) ``` GitHub link: https://github.com/apache/pulsar/discussions/22059#discussioncomment-8495693 ---- This is an automatically sent email for [email protected].
