title: Apache camel graceful route shutdown
body: <p>I have a Camel route which Consumes messages from a Queue and stores the message into a Database. Now I wanted to shut down running camel route manually in a graceful manner. I have a RestEndpoint to be triggered whenever I need to stop Camel route. This endpoint should stop the route. But if there is any in-flight message or transaction running during the shutdown it has to be completed successfully without consuming any new messages from from("") endpoint of camel route and shut down after completing inflight message or transaction. Can anyone help me how Can I code this? </p>
