ARTEMIS-4517 - cancel message references in queue sequence order
> rollback causes loss of message order if concurrent producers commit out of
> order
> ----------------------------------------------------------------------------------
>
> Key: ARTEMIS-4517
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4517
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 2.31.0
> Reporter: Gary Tully
> Assignee: Gary Tully
> Priority: Major
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> As part of ARTEMIS-2458, cancel puts messages back onto the queue on sequence
> id order, but the sequence id is allocated to producers on message send (via
> the message store) and can be unordered w.r.t to a queue view when producer
> transactions overlap.
> The queue has the correct initial producer order, with out of order
> sequenceId.
> When messages are cancelled back to the queue they go back in sqeuenceId
> order in error, giving a consumer out of order messages on the second or
> subsequent delivery attempts.
>
> each queue needs to retain its own sequence and apply to its reference, such
> that messages can be cancelled back and retain the queue order.
