public enum VeniceWriteComputeOperation
extends Enum<VeniceWriteComputeOperation>
implements VeniceDimensionInterface

Dimension values for the VeniceMetricsDimensions.VENICE_WRITE_COMPUTE_OPERATION dimension, representing the phase of a write compute (partial update) operation during ingestion.

Write compute allows clients to send partial updates (e.g., list add/remove, map put/delete) instead of full record replacements. Processing a write compute message involves two phases:

1. Query — Looking up the existing record value from the storage engine to use as the base for applying the partial update.
2. Update — Applying the write compute operations (e.g., collection merges) to produce the final updated record.

Used by the ingestion.write_compute.time metric to break down write compute latency by phase.

Enum Constant Details

QUERY

public static final VeniceWriteComputeOperation QUERY

The lookup phase: reading the existing record value from storage to use as the base for the update

UPDATE

public static final VeniceWriteComputeOperation UPDATE

The update phase: applying write compute operations to the base record to produce the final value

Method Details

values

public static VeniceWriteComputeOperation[] 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 VeniceWriteComputeOperation 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()

All instances of this enum share the same dimension name. Refer to VeniceDimensionInterface.getDimensionName() for more details.
