Subject [jira] Created: (AMQ-747) Redelivery backoff should add random delay for collision avoidance
Date Mon, 12 Jun 2006 16:00:51 GMT
Redelivery backoff should add random delay for collision avoidance
------------------------------------------------------------------

         Key: AMQ-747
         URL: https://issues.apache.org/activemq/browse/AMQ-747
     Project: ActiveMQ
        Type: Improvement

  Components: Connector  
    Versions: 4.0    
    Reporter: Christopher G. Stach II


If a rollback on two messages happens between three transactional deliveries, and the two
messages are redelivered with the same redelivery backoff settings, there is a likelihood
that both messages will cause another rollback to happen.  If maximumRedeliveries is set too
low, or there are a maximumRedeliveries + 1 messages coming in simultaneously, messages may
never get delivered.  Can we get another option for the clients that adds a random backoff
delay adjustment in addition to the constant backoff delay factor?  This would end up working
like most other collision avoidance algorithms.
