> Consumer may miss messages because of inconsistent subscription
> ---------------------------------------------------------------
>
> Key: ROCKETMQ-175
> URL: https://issues.apache.org/jira/browse/ROCKETMQ-175
> Project: Apache RocketMQ
> Issue Type: Bug
> Components: rocketmq-broker
> Affects Versions: 4.0.0-incubating
> Reporter: Eric Liu
> Assignee: Eric Liu
> Fix For: 4.1.0-incubating
>
>
> When consumers in one group have different subscriptions(with tag), broker
> will select the one has latest client version. Although when this consumer
> shutdown, broker would not update the subscription until someone in group
> restart, so other consumers will miss messages by the dead consumer's tag.
> Broker should refresh the group's subscriptions when someone was off-line.
