Parameter | Description |
Message TTL | Expiration time for unconsumed messages. If not acknowledged within the timeout period, the message will be skipped. It ranges from 60 seconds to 15 days. |
Message Retention Policy | Persistent retention: Messages are persistently stored regardless of whether they have been consumed, based on the maximum retention period and storage space. Once the limit is reached, messages will be deleted based on the generation time in ascending order. Maximum retention period: Messages are deleted after this period, calculated from when the message is produced to the topic. The retention policy applies only to acknowledged messages and does not affect unacknowledged messages. Unacknowledged messages are eligible for cleanup only after the Time to Live (TTL) expires. It ranges from 60 seconds to 15 days. Maximum storage space: When the total size of all messages in the namespace reaches this limit, older messages are deleted in chronological order (from oldest to latest) based on their generation time. The minimum value is 10 GB. The configured capacity is allocated from the cluster's storage resources. Consume-and-delete: Messages are asynchronously cleaned up within a certain period after being successfully acknowledged, saving storage space. If a topic has no subscriptions, this asynchronous cleanup applies immediately to newly generated messages. |
Auto-Create Subscriptions | After enabling this feature, clients can auto-create subscriptions. |
