ClassDescriptionAbstractDiffable<T extends Diffable<T>>Abstract diffable object with simple diffs implementation that sends the entire object if object has changed or nothing if object remained the same.AbstractNamedDiffable<T extends NamedDiffable<T>>Abstract diffable object with simple diffs implementation that sends the entire object if object has changed or nothing is object remained the same.Listener when cluster state task is acknowledgedAckedClusterStateUpdateTask<Response>An extension interface to
ClusterStateUpdateTaskthat allows to be notified when all the nodes have acknowledged a cluster state update requestAn event received by the local node, signaling that the cluster state has changed.ClusterInfo is an object representing a map of nodes toDiskUsageand a map of shard ids to shard sizes, seeInternalClusterInfoService.shardIdentifierFromRouting(String)for the key used in the shardSizes mapRepresents a data path on a nodeRepresents the total amount of "reserved" space on a particular data path, together with the set of shards considered.Builder for Reserved Space.Interface for a class used to gather information about a cluster periodically.Utility class to build a predicate that accepts cluster state changesConfigures classes and services that affect the entire cluster.Cluster NamePluginSettings Response for ExtensibilityRepresents the current state of the cluster.Builder for cluster state.Custom cluster state.An interface that implementors use when a class requires a client to maybe have a feature.Metrics for cluster state.A component that is in charge of applying an incoming cluster state to the node internal data structures.A listener to be notified when a cluster state changes.A utility class which simplifies interacting with the cluster state in cases where one tries to take action based on the current state but may want to wait for a new state and retry upon failure.Listener for the observer.Cluster state update task configuration for timeout and priorityBasic task config.Interface that updates the cluster state based on the taskRepresents the result of a batched execution of cluster state update tasksBuilder for cluster state task.The task result.Interface to implement a cluster state change listenerA task that can update the cluster state.Diff<T>Represents difference between states of cluster state partsDiffable<T>Cluster state part, changes in which can be serializedUtility class for a diffableDiffableUtils.DiffableValueReader<K,V extends Diffable<V>> Implementation of the ValueSerializer that wraps value and diff readers.DiffableUtils.DiffableValueSerializer<K,V extends Diffable<V>> Serializer for Diffable map values.Provides read and write operations to serialize keys of mapDiffableUtils.MapDiff<K,T, M> Represents differences between two maps of objects and is used as base class for different map implementations.Serializer for non-diffable map valuesImplementation of ValueSerializer that serializes immutable setsProvides read and write operations to serialize map values.Encapsulation class used to represent the amount of disk used on a node.ClusterInfoServicethat provides empty maps for disk usage and shard sizesThrown byDiff.apply(T)methodInternalClusterInfoService provides the ClusterInfoService interface, routinely updated on a timer.Used to apply state updates on nodes that are not necessarily cluster-managerEnables listening to cluster-manager changes events of the local node (when the local node becomes the cluster-manager, and when the local node cease being a cluster-manager).Deprecated.Deprecated.As of 2.2, because supporting inclusive language, replaced byClusterManagerNodeChangePredicateMergableCustomMetadata<T extends Metadata.Custom>Interface to allow mergingMetadata.Custom.Diff that also support NamedWriteable interfaceDiff that also supportVersionedNamedWriteableinterfaceNamedDiffableValueSerializer<T extends NamedDiffable<T>>Value Serializer for named diffablesThis component is responsible for maintaining connections from this node to all the nodes listed in the cluster state, and for disconnecting from nodes once they are removed from the cluster state.Thrown when a node join request or a cluster-manager ping reaches a node which is not currently acting as a cluster-manager or when a cluster state update task is to be executed on a node that is no longer cluster-manager.Deprecated.As of 2.2, because supporting inclusive language, replaced byNotClusterManagerExceptionInformation passed during repository cleanupEntry in the collection.Meta data about restore processes that are currently executingBuilder of the restore.Restore metadataRepresents status of a restored shardShard restore process stateA class that represents the snapshot deletions that are in progress in the cluster.A class representing a snapshot deletion request entry in the cluster state.State of the deletions.Meta data about snapshots that are currently executingEntry in the collection.Status of shard snapshots.The shard state.State of the snapshots.An exception to cluster state listener that allows for timeouts and for post added notifications.
