Hi, There are two offsets for a queue/partition:
* broker min offset: the minimum message offset in the current broker, which points to the earliest message. * broker max offset: the maximum message offset in the current broker, which points to the newest message. As for consumer, should concern the consumer offset(min offset<= consumer offset <= max offset). The consumer offset will be updated automatically according to the consumer consumed progress if you are using the PushConsumer, and the consumer offset can be changed easily through MQAdmin tool. If you noticed that the consumer offset always is lower than broker max offset, you should keep a watchful eye on your consume logic, check whether it's blocked by some remoting calls. It's worth noting that the consumer offset is not accurate and real-time if you are using TAG/SQL to filter the message. Let me know if you have any other questions.
