> Key: QPID-5907
> URL: https://issues.apache.org/jira/browse/QPID-5907
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Rob Godfrey
> Assignee: Rob Godfrey
> Fix For: 0.29
>
>
> Currently the broker does not become active until all persistent queues have
> been fully recovered. In the case where queues have a large number of
> entries this may take considerable time.
> By adding a mechanism by which the queue recovery can be done in the
> background while the broker becomes operational, the return to operation time
> of the broker can be improved.
> Newly published messages should not "overtake" messages already in the queue
> (save for already permitted exceptions, such as priority queues).
> Note that int he case of priority queues, if consumers attach to the queue
> before the queue is fully recovered older but lower priority messages may be
> delivered before newer, higher priority, messages
