Enum CacheDistributionMode

java.lang.Object

java.lang.Enum<CacheDistributionMode>

org.apache.ignite.cache.CacheDistributionMode

All Implemented Interfaces:

Serializable, Comparable<CacheDistributionMode>

public enum CacheDistributionMode
extends Enum<CacheDistributionMode>

This enum defines mode in which partitioned cache operates.

Partitioned distribution mode can be configured via CacheConfiguration.getDistributionMode() configuration property.

Enum Constant Summary

Enum Constants

Enum Constant and Description
CLIENT_ONLY Mode in which local node does not cache any data and communicates with other cache nodes via remote calls.
NEAR_ONLY Mode in which local node will not be either primary or backup node for any keys, but will cache recently accessed keys in a smaller near cache.
NEAR_PARTITIONED Mode in which local node may store primary and/or backup keys, and also will cache recently accessed keys.
PARTITIONED_ONLY Mode in which local node may store primary or backup keys, but does not cache recently accessed keys in near cache.

Enum Constant Detail

CLIENT_ONLY

public static final CacheDistributionMode CLIENT_ONLY

Mode in which local node does not cache any data and communicates with other cache nodes via remote calls.

NEAR_ONLY

public static final CacheDistributionMode NEAR_ONLY

Mode in which local node will not be either primary or backup node for any keys, but will cache recently accessed keys in a smaller near cache. Amount of recently accessed keys to cache is controlled by near eviction policy.

See Also:

CacheConfiguration.getNearEvictionPolicy()

NEAR_PARTITIONED

public static final CacheDistributionMode NEAR_PARTITIONED

Mode in which local node may store primary and/or backup keys, and also will cache recently accessed keys. Amount of recently accessed keys to cache is controlled by near eviction policy.

See Also:

CacheConfiguration.getNearEvictionPolicy()

PARTITIONED_ONLY

public static final CacheDistributionMode PARTITIONED_ONLY

Mode in which local node may store primary or backup keys, but does not cache recently accessed keys in near cache.

Method Detail

values

public static CacheDistributionMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CacheDistributionMode c : CacheDistributionMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static CacheDistributionMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null

fromOrdinal

@Nullable
public static CacheDistributionMode fromOrdinal(int ord)

Efficiently gets enumerated value from its ordinal.

Parameters:

ord - Ordinal value.

Returns:

Enumerated value or null if ordinal out of range.
