Enum Class VeniceIngestionDestinationComponent

java.lang.Object

java.lang.Enum<VeniceIngestionDestinationComponent>

com.linkedin.venice.stats.dimensions.VeniceIngestionDestinationComponent

All Implemented Interfaces:

VeniceDimensionInterface, Serializable, Comparable<VeniceIngestionDestinationComponent>, Constable

public enum VeniceIngestionDestinationComponent
extends Enum<VeniceIngestionDestinationComponent>
implements VeniceDimensionInterface

Dimension enum representing the destination component in the ingestion flow. Used for metrics like ingestion latency between components.

Note: Similar to VeniceIngestionSourceComponent. TThese are 2 different enums with same values to provide type safety when defining and recording metrics.

Method Details

values

public static VeniceIngestionDestinationComponent[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static VeniceIngestionDestinationComponent valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

getDimensionName

public VeniceMetricsDimensions getDimensionName()

Description copied from interface: VeniceDimensionInterface

Dimension name: Returns the VeniceMetricsDimensions for the enum. All the instances of a Enum class should have the same dimension name. Ideally this could have been a static variable/method in the Enum class, but to enforce having this method via this interface, it is made as a non-static method.

Specified by:

getDimensionName in interface VeniceDimensionInterface

getDimensionValue

public String getDimensionValue()

Description copied from interface: VeniceDimensionInterface

Dimension value: Returns the dimension value for each enum instance.

Specified by:

getDimensionValue in interface VeniceDimensionInterface
