public class ReplicatedHazelcastAggregationRepository extends HazelcastAggregationRepository
A Hazelcast-based AggregationRepository implementing RecoverableAggregationRepository and OptimisticLockingAggregationRepository. Defaults to thread-safe (non-optimistic) locking and recoverable strategy. Hazelcast settings are given to an end-user and can be controlled with repositoryName and persistentRespositoryName, both are IMap <String, Exchange>. However ReplicatedHazelcastAggregationRepository can run it's own Hazelcast instance, but obviously no benefits of Hazelcast clustering are gained this way. If the ReplicatedHazelcastAggregationRepository uses it's own local HazelcastInstance it will DESTROY this instance on HazelcastAggregationRepository.doStop(). You should control HazelcastInstance lifecycle yourself whenever you instantiate ReplicatedHazelcastAggregationRepository passing a reference to the instance.
