Route priority

[larasith]

Is there any way to prioritize routes executions?

[davsclaus]

Can you post more details about your questions, so we are sure what you ask about?

Do you mean startup order for camel routes?

http://camel.apache.org/configuring-route-startup-ordering-and-autostartup.html

or bundle-level startup

I want to give preference to an execution of a route than others, for example, if an user requests something, the route that he executes should have more priority than the automatic routes that start with "<from uri='file:..."

Hi

You can use the CBR[1] to checks the message priority to decide which route the message will be sent to.

Sorry, but  i don't mean that. I want to if an automatic route, so file consumer, is working and, in the same moment, a human execute a other route, so a webservice implemented with cxfEndpoint, this route has more priority than the first one.

My intention is that the human waits as short as possible.

Current Camel doesn't provides any priority control on the route.  As each route handle the message separately. For your case, Camel start two different thread or thread pool to poll the directory and handle the soap request.

If you want to camel handle the message in these route differently, I think you can do some thing to change the file polling endpoint wait time or do some configuration on the thread pool.

Ok, thanks. I try to balance with two servers

Thread priorities in Java is flawed and doesn't work. So you can't really within a JVM turn up/down priorities in threads/thread pools.

You can build an architecture with some sort of priority queues, so important messages is picked up sooner/faster than low priority queues.

For example Apache ActiveMQ supports priorities on its queues.
