Jgroups Raft Cluster Service

Spring Boot auto-configuration for the Camel JGroups Raft Cluster Service.

This starter provides leader election for Camel routes using JGroups Raft consensus protocol. It integrates with Camel’s CamelClusterService SPI so you can use the clustered route controller to ensure only one instance of a route runs across a cluster.
