Previously queues were only monitoring channels with subscribers or to which ack-requiring messages had been delivered. Now queues also monitor channels from which they have received transactional publishes. Queues record the last tx id they have seen from a channel. This then makes it easy and efficient to find the associated tx record in the queue's process dictionary when a channel process dies - the alternative would be to scan the tx records for matching channel pids - and perform the required rollback activities for the tx. |
