Subject Re: How can avoid that the broker master loadbalance messages equitably between two brokers ?
Date Thu, 27 May 2010 18:13:46 GMT

Try using consumer prioritization. 

http://activemq.apache.org/consumer-priority.html

>From the web page - 

"The way it works is that the broker will simply order any queue consumers
according to their priorities and send messages to the highest priority
consumers first. Once a particular consumer has its prefetch buffer filled
up, the broker will begin to dispatch messages to consumers of lower
priorities."

I have tried this across a 2-broker NoB and it seems to work fine. 

So what you want to do is assign the fast consumer on  br2 a higher
priority. Messages will then be dispatched to the fast consumer until its
prefetch limit has been reached (i.e., the fast consumer becomes a slow
consumer); at which time, the messages will then begin flowing to the
low-priority consumer on br1. Messages will again flow to the fast consumer
as soon as it addresses its prefetch limit issue.
