Luca Burgazzoli updated CAMEL-17726:
------------------------------------
Description:
The camel-controlbus allow to control routes i.e. you can stop it.
In some circumstances it may be useful to stop a route as pat of the error
handling strategy and let the health check report the application as not ready.
As example, one may think to do something like:
{code:java}
from("timer:tick")
.routeId("main")
.process(e -> { throw new RuntimeCamelException("error happended")); })
.errorHandler(deadLetterChannel("controlbus:route?routeId=current&action=stop"))
.to("log:info?showAll=true");
{code}
This would result in the route being stopped but the health check won't report
the application as not ready because:
- the RouteHealthCheck code would report the route as UNKNOWN
- the RouteError is cleared up when the route is stopped.
It may be useful to enrich the control-bus with some additional *failure*
attributes, something like:
{code}
controlbus:route?routeId=current&action=stop&fail=true&propagateException=true"
{code}
Where:
* *fail=true* tells the control bus that the route should be stopped but also
marked as failed
* *propagateException=true* tells the control bus that if the exchange is
failed, the exception need to be propagated to the route
