Class DistributedEvent

java.lang.Object

org.hawkular.alerts.api.services.DistributedEvent

public class DistributedEvent
extends Object

An event that represents a change of a trigger distribution in the current node. In cluster topologies triggers are distributed across all available nodes. In this way, a trigger is only executed by one node of the cluster, allowing to scale in horizontal way. When a trigger is added, modified or removed, the core engine or third party alerters should be notified to perform load/unload operations of the trigger in their own logic. Each node will received the events related which triggers should be loaded/unloaded. DistributedEvent targets only triggers and the granularity is the whole trigger, meaning that a change on a condition or a dampening is considered an update of an existing trigger. DistributedEvent are invoked via DistributedListener which are registered via DefinitionsService.
