Pausing Routes
Hi,
If we have a route where we are consuming messages and posting to a REST
service which occasionally returns 503 when busy, is there a way to pause
the route for a while so we don't hammer the busy REST service? We also
have other routes in the same Camelcontext that we would not want to pause.
We have tried stopping/starting the route but this seems slow - I suspect
it is starting stopping the underlying thread pools.
Thanks, Tom

No, look at [1] for it's complete documentation.

Does @consume not create an underlying route ?

No @Consume is for using a bean to consume messages from a camel endpoint.

Hi Claus,
Why is graceful shutdown important for suspend/resume?
I think this is what I need..
myCamelContext.suspendRoute("routeId");
myCamelContext.resumeRoute("routeId");
We are using @consume, is there a way to specify routeId when using
@consume? or a way to call suspendRoute from @consume?
Thanks, Tom

You can use JMX, for example the examples/camel-example-management
The API on CamelContext should have methods to suspend/resume routes.
And this is the API you should use,
as they use the proper logic with graceful shutdown
http://camel.apache.org/graceful-shutdown.html
And there is a FAQ to stop a route from a route

Thanks, is there an example of how to suspend a route?

Hi
Some routes support suspend/resume.
