Subject [jira] [Commented] (AMQ-3597) Enable RedeliveryPolicy to determine next delay independent of the consumer
Date Fri, 18 Nov 2011 18:52:51 GMT


Timothy Bish commented on AMQ-3597:

I think there's a bit of misunderstanding regards redelivery vs redispatch of a message. 
From the client side when a transaction is rolled back the messages are redelivered from the
consumers own internal storage and the broker is only notified after one retry is attempted
and fails that redelivery has occurred.  The client continues to retry delivery each time
the transaction is rolled back until some configured limit is reached (if one is desired)
and then poisons the message which causes it to be sent to the DLQ.  

If the consumer were to be closed for some reason before the transaction was committed then
the broker would need to redispatch the message to another consumer.  To this new consumer
its the first time that its ever seen this message regardless of whether it a new message
or one that's been redelivered so the need for a delay in this case seems odd to me but perhaps
I don't fully understand your use case or the problem you are trying to solve.  

Perhaps you might find the solution defined in AMQ-2710 to be of use in your scenario.  Here
the messages that are poisoned because they were deemed undeliverable are moved from the DLQ
and rescheduled for send after a delay using the brokers own scheduled message feature.  

If this isn't want you are going for then perhaps you can take a step back and better define
what the use case is and what problem you are trying to solve.  The current implementation
of the consumer doesn't have an easy way to delay a message on dispatch only on rollback so
if you want to add something like that you'd need to do some work.

> Currently the redelivery is bound to the consumer instance requiring the end user to
use the same message consumer instance. This is due to the fact that the redelivery delay
is computated based on the previous redelivery delay (stored with the consumer instance) and
not based on the redeliveryCount of the message.
