check sameple of MyServiceNode.java for more details
Any class that implements Node can be mapped to ConsistentHashRouter.
Your custom Node represents a real physical node, which supports numbers of virtual nodes , the replicas of physical node.
When adding new Node to the ConsistentHashRouter, you can specify how many virtual nodes should be replicated.
By default , ConsistentHashRouter will use MD5 to hash a node, you may specify your custom hash function by implementing HashFunction
