> Support hardening/persisting the JMSRedeliveryFlag across restarts
> ------------------------------------------------------------------
>
> Key: AMQ-5068
> URL: https://issues.apache.org/jira/browse/AMQ-5068
> Project: ActiveMQ
> Issue Type: Bug
> Components: Message Store
> Affects Versions: 5.9.0
> Reporter: Gary Tully
> Assignee: Gary Tully
> Labels: JMSRedelivered, persistence, recovery, redelivery
> Fix For: 5.10.0
>
>
> WMQ supports a HARDENBO[1] flag on the redelivery flag impl. Which persists
> before dispatch. And has a corresponding performance impact.
> So we need to implement an additional journal command to persist delivery
> attempts and update the counter on restart/recovery to get parity.
> This will allow the redeliverFlag to be guaranteed to flag a potential
> duplicate dispatch in the event of a hard broker failure just after dispatch.
