Jaskey Lam created ROCKETMQ-105:
Summary: Implementation of consumerOffset and maxOffset are
Project: Apache RocketMQ
Issue Type: Wish
Components: rocketmq-broker, rocketmq-client, rocketmq-store
Affects Versions: 4.0.0-incubating
Reporter: Jaskey Lam
This issue does not affect all functionality, but it indeed is a problem for
user to understand the principle of RocketMQ.
User might consider consumer offset is the offset where I have consumed. for
example if CG1 have a consumer offset 100 of topicA-q1, I may propabaly
consider message with offset 100 has been cosumed. But actully, it is not. The
message with offset 100 is the next target when I pull from.
- Max Offset
User might consider this is the offset of the latest message in a queue. But it
is not, it is indicating that next offset when new message arrived.
If possible , any of the below two things should be taken into consideration
1. the implementaion should be changed to be closer to the presentative
judgment of human
2. rename the concept to clarify how it really implemented.
