Subject [jira] [Created] (AMQ-3893) Adjust topic policy entry in default configuration
Date Fri, 22 Jun 2012 14:03:42 GMT
Dejan Bosanac created AMQ-3893:
----------------------------------

             Summary: Adjust topic policy entry in default configuration
                 Key: AMQ-3893
                 URL: https://issues.apache.org/jira/browse/AMQ-3893
             Project: ActiveMQ
          Issue Type: Improvement
    Affects Versions: 5.6.0
            Reporter: Dejan Bosanac
            Assignee: Dejan Bosanac
             Fix For: 5.7.0


With https://issues.apache.org/jira/browse/AMQ-2400 we introduced vmCursor and memory limit
for all topics by default. While this improved throughput in high-volume topic scenarios it
can cause a single slow consumer block the producer and affect all other producers.

The proposition is to use pendingMessageLimitStrategy by default and limit the number of messages
we're retaining by default for consumer as a strategy for dealing with slow consumers (instead
of blocking)

We also need to add more documentation explaining all aspects of these settings and their
consequences.
