Enum Class StorageMode

java.lang.Enum<StorageMode>

com.linkedin.venice.meta.StorageMode

All Implemented Interfaces:

VeniceEnumValue, Serializable, Comparable<StorageMode>, Constable

public enum StorageMode
extends Enum<StorageMode>
implements VeniceEnumValue

Per-version storage mode controlling where data for a Venice store version is persisted relative to the optional external storage system. Mirrors the storageMode field staged on StoreVersion (StoreMetaValue v44) by PR #2814.

Read-side routing is selected separately by ExternalStorageReadMode at the store level.

Enum Constant Details

INTERNAL

public static final StorageMode INTERNAL

Default. Data persisted in Venice local storage only. Current behavior.

DUAL_WRITE

public static final StorageMode DUAL_WRITE

Data is written to both Venice local storage and the configured external storage. The specific dual-write implementation — leader-consumer-pipeline vs Venice Push Job — is selected by separate server/VPJ configuration, not by this enum.

EXTERNAL

public static final StorageMode EXTERNAL

External-storage-only. Venice's data partition becomes NoOp while metadata partitions are still persisted locally for checkpointing.

Method Details

values

public static StorageMode[] 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 StorageMode 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

valueOf

public static StorageMode valueOf(int value)

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:

value - 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

getValue

public int getValue()

Specified by:

getValue in interface VeniceEnumValue
