Class DataStreamLifecycle

java.lang.Object

org.elasticsearch.cluster.metadata.DataStreamLifecycle

All Implemented Interfaces:

Diffable<DataStreamLifecycle>, SimpleDiffable<DataStreamLifecycle>, Writeable, ToXContent, ToXContentObject

public class DataStreamLifecycle
extends Object
implements SimpleDiffable<DataStreamLifecycle>, ToXContentObject

Holds the data stream lifecycle metadata that are configuring how a data stream is managed. Currently, it supports the following configurations: - enabled - data retention - downsampling

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	DataStreamLifecycle.Builder	This builder helps during the composition of the data stream lifecycle templates.
static final record	DataStreamLifecycle.Downsampling	Downsampling holds the configuration about when should elasticsearch downsample a backing index.
static final record	DataStreamLifecycle.Retention	Retention is the least amount of time that the data will be kept by elasticsearch.

Constructor Details

DataStreamLifecycle

public DataStreamLifecycle()

DataStreamLifecycle

public DataStreamLifecycle(@Nullable
 DataStreamLifecycle.Retention dataRetention,
 @Nullable
 DataStreamLifecycle.Downsampling downsampling,
 @Nullable
 Boolean enabled)

DataStreamLifecycle

public DataStreamLifecycle(StreamInput in)
                    throws IOException

Throws:

IOException

Method Details

isDataStreamsLifecycleOnlyMode

public static boolean isDataStreamsLifecycleOnlyMode(Settings settings)

Check if DATA_STREAMS_LIFECYCLE_ONLY_SETTING_NAME is present and set to true, indicating that we're running in a cluster configuration that is only expecting to use data streams lifecycles.

Parameters:

settings - the node settings

Returns:

true if DATA_STREAMS_LIFECYCLE_ONLY_SETTING_NAME is present and set

isEnabled

public boolean isEnabled()

Returns true, if this data stream lifecycle configuration is enabled and false otherwise

getEffectiveDataRetention

@Nullable
public TimeValue getEffectiveDataRetention()

The least amount of time data should be kept by elasticsearch.

Returns:

the time period or null, null represents that data should never be deleted.

getDownsamplingRounds

@Nullable
public List<DataStreamLifecycle.Downsampling.Round> getDownsamplingRounds()

The configured downsampling rounds with the `after` and the `fixed_interval` per round. If downsampling is not configured then it returns null.
