Record Class DataStreamLifecycle.DownsamplingRound

java.lang.Object

java.lang.Record

org.elasticsearch.cluster.metadata.DataStreamLifecycle.DownsamplingRound

Record Components:

after - is a TimeValue configuring how old (based on generation age) should a backing index be before downsampling

fixedInterval - contains the interval that the backing index is going to be downsampled.

All Implemented Interfaces:

Writeable, ToXContent, ToXContentObject

Enclosing class:

DataStreamLifecycle

public static record DataStreamLifecycle.DownsamplingRound(TimeValue after, DateHistogramInterval fixedInterval)
extends Record
implements Writeable, ToXContentObject

A round represents the configuration for when and how elasticsearch will downsample a backing index.

Constructor Details

DownsamplingRound

public DownsamplingRound(TimeValue after,
 DateHistogramInterval fixedInterval)

Creates an instance of a DownsamplingRound record class.

Parameters:

after - the value for the after record component

fixedInterval - the value for the fixedInterval record component

Method Details

read

public static DataStreamLifecycle.DownsamplingRound read(StreamInput in)
                                                  throws IOException

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

Specified by:

toXContent in interface ToXContent

Throws:

IOException

fromXContent

public static DataStreamLifecycle.DownsamplingRound fromXContent(XContentParser parser,
 Void context)
                                                          throws IOException

Throws:

IOException

toString

public String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

after

public TimeValue after()

Returns the value of the after record component.

Returns:

the value of the after record component

fixedInterval

public DateHistogramInterval fixedInterval()

Returns the value of the fixedInterval record component.

Returns:

the value of the fixedInterval record component
