Subject Understanding the Exclusive Consumer
Date Wed, 21 Apr 2010 15:35:39 GMT

In the ActiveMQ doc http://activemq.apache.org/exclusive-consumer.html it
states

The broker will pick a single MessageConsumer to get all the messages for a
queue to ensure ordering. If that consumer fails, the broker will auto
failover and choose another consumer.

Is this a consumer master slave relationship, the broker will send all
messages to the designated consumer, and the consumer passes the messages
onto the other consumers. Or does the broker send the messages to all the
consumers, but only one consumer acknowledges them,  so if that consumer
dies the other consumer can then pick up where the first consumer died.

If there is a link that covers Queue consumer clusters in more depth, I
would be grateful if you could post it.

Thanks Tony

Thanks Tony
