 SnapshotsInProgress old)

Computes a map of repository shard id to set of generations, containing all shard generations that became obsolete and may be deleted from the repository as the cluster state moved from the given old value of SnapshotsInProgress to this instance.

getWriteableName

public String getWriteableName()

Description copied from interface: VersionedNamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

Specified by:

getWriteableName in interface VersionedNamedWriteable

getMinimalSupportedVersion

public Version getMinimalSupportedVersion()

Description copied from interface: VersionedNamedWriteable

The minimal version of the recipient this object can be sent to

Specified by:

getMinimalSupportedVersion in interface VersionedNamedWriteable

readDiffFrom

public static NamedDiff<ClusterState.Custom> readDiffFrom(StreamInput in)
                                                   throws IOException

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Throws:

IOException

toXContent

public XContentBuilder toXContent(XContentBuilder builder,
 ToXContent.Params params)
                           throws IOException

Description copied from interface: ClusterState.Custom

Serialize this ClusterState.Custom for diagnostic purposes, exposed by the

GET _cluster/state

API etc. The XContent representation does not need to be 100% faithful since we never reconstruct a cluster state from its XContent representation, but the more faithful it is the more useful it is for diagnostics.

Specified by:

toXContent in interface ClusterState.Custom

Specified by:

toXContent in interface ToXContent

Throws:

IOException

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

startedEntry

public static SnapshotsInProgress.Entry startedEntry(Snapshot snapshot,
 boolean includeGlobalState,
 boolean partial,
 Map<String,IndexId> indices,
 List<String> dataStreams,
 long startTime,
 long repositoryStateId,
 ImmutableOpenMap<ShardId,SnapshotsInProgress.ShardSnapshotStatus> shards,
 Map<String,Object> userMetadata,
 Version version,
 List<SnapshotFeatureInfo> featureStates)

Creates the initial SnapshotsInProgress.Entry when starting a snapshot, if no shard-level snapshot work is to be done the resulting entry will be in state SnapshotsInProgress.State.SUCCESS right away otherwise it will be in state SnapshotsInProgress.State.STARTED.

startClone

public static SnapshotsInProgress.Entry startClone(Snapshot snapshot,
 SnapshotId source,
 Map<String,IndexId> indices,
 long startTime,
 long repositoryStateId,
 Version version)

Creates the initial snapshot clone entry

Parameters:

snapshot - snapshot to clone into

source - snapshot to clone from

indices - indices to clone

startTime - start time

repositoryStateId - repository state id that this clone is based on

version - repository metadata version to write

Returns:

snapshot clone entry

completed

public static boolean completed(Collection<SnapshotsInProgress.ShardSnapshotStatus> shards)

Checks if all shards in the list have completed

Parameters:

shards - list of shard statuses

Returns:

true if all shards have completed (either successfully or failed), false otherwise
