Hi Jose, I'm using the prioritizedMessages=true because of the JMS grouping feature.
In the application I'm running, one of the most important features is that messages with the same group ID are not processed in parallel, thus the message grouping ensuring the same consumer always gets the message with the same ID, so that they are processed sequentially. The most recent requirement was to additionally separate processing of messages with the low and high priority, but by still keeping the message grouping rule defined above. What I meant to achieve that way was for different consumers to process low and high priority message, with the same group ID, but while keeping the sequential message processing order. Any other ideas on how to achieve that? One other idea of mine was to define a route which would say something like this: from("jms:queue:test?concurrentConsumers=1") .choice() .when(header("JMSPriority").isGreaterThanOrEqualTo(4)) .to("jms:queue:normalPriority") .otherwise() .to("jms:queue:lowPriority") .endChoice(); However, in that case, the messages consumed from the normalPriority and lowPriority queues might be processed in parallel, which I'm trying to avoid.
