Class Shard

  • All Implemented Interfaces:
    akka.actor.Actor, akka.actor.Stash, akka.actor.StashFactory, akka.actor.StashSupport, akka.actor.UnrestrictedStash, akka.dispatch.RequiresMessageQueue<akka.dispatch.DequeBasedMessageQueueSemantics>, akka.persistence.AbstractPersistentActorLike, akka.persistence.Eventsourced, akka.persistence.PersistenceIdentity, akka.persistence.PersistenceRecovery, akka.persistence.PersistenceStash, akka.persistence.Snapshotter, org.opendaylight.controller.cluster.common.actor.ExecuteInSelfActor
    public class Shard
extends org.opendaylight.controller.cluster.raft.RaftActor
    A Shard represents a portion of the logical data tree.

    Our Shard uses InMemoryDataTree as it's internal representation and delegates all requests it
