public @interface DiscoverySpiOrderSupport

This annotation is for all implementations of DiscoverySpi that support proper node ordering. This includes:

• Every node gets an order number assigned to it which is provided via ClusterNode.order() method. There is no requirement about order value other than that nodes that join grid at later point of time have order values greater than previous nodes.
• All EventType.EVT_NODE_JOINED events come in proper order. This means that all listeners to discovery events will receive discovery notifications in proper order.
