That code ought to be triggered on the onInit callback, then the leader election can be run prior to routes starting up. If not then feel free to log a JIRA and as usual we love contributions, so patches is welcome. > Also for this issues Hazelcast with its distributed locks can be used. > > So what is the best way to have the backup routes and only single running > route among the multiple similar routes? > Does camel have a standard solution for such issues? > Zookeeper is good but it requires to run zookeeper instances.
