public class ClusterStateChangeEvent extends EventAdapter
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(IgnitePredicate, long, int...)- asynchronously querying events occurred on the nodes specified, including remote nodes.
IgniteEvents.localQuery(IgnitePredicate, int...)- querying only local events stored on this local node.
IgniteEvents.localListen(IgnitePredicate, int...)- listening to local grid events (events from remote nodes not included).
It is highly recommended to enable only those events that your application logic requires
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 SPI if they are disabled in Ignite configuration.
