All Implemented Interfaces:

Serializable, Comparable<Event>, Event

public class DrRemoteDcNodeEvent
extends EventAdapter

Remote replication node event. Describes events with nodes in remote data center.

Grid events are used for notification about what happens within the grid. Note that by design Ignite keeps all events generated on the local node locally and it provides APIs for performing a distributed queries across multiple nodes:

• IgniteEvents.remoteQuery(org.apache.ignite.lang.IgnitePredicate, long, int...) - asynchronously querying events occurred on the nodes specified, including remote nodes.
• IgniteEvents.localQuery(org.apache.ignite.lang.IgnitePredicate, int...) - querying only local events stored on this local node.
• IgniteEvents.localListen(org.apache.ignite.lang.IgnitePredicate, int...) - listening to local grid events (events from remote nodes not included).

User can also wait for events using method IgniteEvents.waitForLocal(org.apache.ignite.lang.IgnitePredicate, int...).

Events and Performance

It is highly recommended to enable only those events that your application logic requires by using IgniteConfiguration.getIncludeEventTypes() method in Ignite configuration. Note that certain events are required for Ignite's internal operations and such events will still be generated but not stored by event storage if they are disabled in Ignite configuration.
