Timothy Bish closed AMQ-6234.
-----------------------------
Resolution: Workaround
> Cannot configure the load balancing count when using Message Groups
> -------------------------------------------------------------------
>
> Key: AMQ-6234
> URL: https://issues.apache.org/jira/browse/AMQ-6234
> Project: ActiveMQ
> Issue Type: New Feature
> Components: Documentation
> Affects Versions: 5.10.0
> Environment: Centos 6.7; Oracle Java 1.6.0_30
> Reporter: I McClure
> Labels: messagegroups
>
> We are seeing ActiveMQ configure the first 10 messages with different
> JMSXGroupID values to the same consuming node before distributing subsequent
> messages across the attached consumers.
> We need to be able to configure this value down to 1 to allow us to evenly
> balance the load across the consumers in a round robin fashion.
> But we cannot see from the documentation how to configure this property.
> For example:
> 1 AMQ broker with a queue that has 3 attached consumers.
> Sending a message with a JMSXGroupID of 'A' goes to consumer 1
> The next 9 messages with different JMSXGroupIDs also go to consumer 1
> The 11th message with a different JMSXGroupdID goes to consumer 2
> This results in an unevenly balanced cluster of consumers when utilising
> Message Groups.
