Minal Bhalodi updated CAMEL-15568:
----------------------------------
Description:
We are using Apache Camel 3.2.0. We update camel routes at runtime using below
code.
// update routes in camel contexts. Definitions are in XML files
ModelCamelContext mcc = camelContext.adapt(ModelCamelContext.class);
mcc.addRouteDefinitions({{workflowDefinitionsList}}); {{//
workflowDefinitionsList is the list of XML routes}}
*Problem Statement*: Dynamic routes updates causes few requests to fail at
runtime. When these routes are being updated, we also call getRoute to serve
live traffic.
Since addRouteDefinitions first delete routes given in
{{workflowDefinitionsList}} from camel context and then add those routes back
to camelcontext, These routes won't be available for few mili second and that
causes request to fails.
Route route = exchange.getContext().getRoute(workflowRouteId); // get route
Since there can be only one CamelContext per Application, I am not sure how can
I resolve this issue. Is there any other method available where we can PATCH
routes changes at runtime. Dynamic route updates shouldn't cause few requests
to fails.
{{Here is camel 3 code for addRouteDefinitions method:}}
{{}}
{{}}
{code:java}
{code}
{{// public synchronized void addRouteDefinitions(Collection<RouteDefinition>
routeDefinitions) throws Exception \{ if (routeDefinitions != null &&
!routeDefinitions.isEmpty()) { List<RouteDefinition> list = new ArrayList();
routeDefinitions.forEach((r) -> { if (this.routeFilter == null ||
(Boolean)this.routeFilter.apply(r)) { list.add(r); } });
this.removeRouteDefinitions(list); this.routeDefinitions.addAll(list); if
(this.shouldStartRoutes()) \{
((ModelCamelContext)this.getCamelContext().adapt(ModelCamelContext.class)).startRouteDefinitions(list);
} } }}}{{}}

*Problem Statement*: Dynamic routes updates causes few requests to fail at
runtime. When these routes are being updated, we also serve requests using
those routes from same CamelContext and few Requests fails.
Since there can be only one CamelContext per Application, I am not sure how can
I resolve this issue.
My application’s code to update routes at runtime: Here we can see that to
add/update routes, these code first delete all routes and then add them back.
These affects the live traffic and requests fails.:
