org.opensearch.gateway.remote	Package containing class to perform operations on remote cluster state

Class	Description
AsyncShardFetch<T extends BaseNodeResponse>	Allows to asynchronously fetch shard related data from other nodes for allocation, without blocking the cluster update thread.
AsyncShardFetch.FetchResult<T extends BaseNodeResponse>	The result of a fetch operation.
AsyncShardFetch.Lister<NodesResponse extends BaseNodesResponse<NodeResponse>,NodeResponse extends BaseNodeResponse>	An action that lists the relevant shard data that needs to be fetched.
BaseGatewayShardAllocator	An abstract class that implements basic functionality for allocating shards to nodes based on shard copies that already exist in the cluster.
ClusterStateUpdaters	Updates cluster state
CorruptStateException	This exception is thrown when OpenSearch detects an inconsistency in one of it's persistent states.
DanglingIndicesState	The dangling indices state is responsible for finding new dangling indices (indices that have their state written on disk, but don't exists in the metadata of the cluster), and importing them into the cluster.
Gateway	The Gateway
Gateway.GatewayStateRecoveredListener	The lister for state recovered.
GatewayAllocator	Allocator for the gateway

MetadataStateFormat<T>	MetadataStateFormat is a base class to write checksummed XContent based files to one or more directories in a standardized directory structure.
MetaStateService	Handles writing and loading Manifest, Metadata and IndexMetadata
PersistedClusterStateService	Stores cluster metadata in a bare Lucene index (per data path) split across a number of documents.
PersistedClusterStateService.OnDiskState	The on disk state.
PersistedClusterStateService.Writer	Writer for cluster state service
