org.apache.camel.component.zookeepermaster.policy.MasterRoutePolicy
All Implemented Interfaces:
AutoCloseable, org.apache.camel.CamelContextAware, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.HasCamelContext, org.apache.camel.spi.RoutePolicy, org.apache.camel.StatefulService, org.apache.camel.SuspendableService
@ManagedResource(description="Managed MasterRoutePolicy") public class MasterRoutePolicy extends org.apache.camel.support.RoutePolicySupport implements org.apache.camel.CamelContextAware
RoutePolicy to run the route in master/slave mode.

Important: Make sure to set the route to autoStartup=false as the route lifecycle is controlled by this route policy which will start/stop the route accordingly to being the master in the zookeeper cluster group.
