Class NearCacheConfiguration<K,V>

java.lang.Object

org.apache.ignite.configuration.NearCacheConfiguration<K,V>

All Implemented Interfaces:

Serializable

public class NearCacheConfiguration<K,V>
extends Object
implements Serializable

Client (near) cache configuration.

Distributed cache can also be fronted by a Near cache, which is a smaller local cache that stores most recently or most frequently accessed data. Just like with a partitioned cache, the user can control the size of the near cache and its eviction policies.

Constructor Detail

NearCacheConfiguration

public NearCacheConfiguration()

Empty constructor.

NearCacheConfiguration

public NearCacheConfiguration(NearCacheConfiguration<K,V> ccfg)

Creates near cache configuration copying properties from passed in configuration.

Parameters:

ccfg - Configuration to copy.

Method Detail

getNearEvictionPolicy

@Deprecated
public EvictionPolicy<K,V> getNearEvictionPolicy()

Deprecated. Use getNearEvictionPolicyFactory() instead.

Gets near eviction policy. By default, returns null which means that evictions are disabled for near cache.

Returns:

Near eviction policy.

See Also:

CacheConfiguration.getEvictionPolicy()

setNearEvictionPolicy

@Deprecated
public NearCacheConfiguration<K,V> setNearEvictionPolicy(EvictionPolicy<K,V> nearEvictPlc)

Deprecated. Use setNearEvictionPolicyFactory(Factory) instead.

Sets near eviction policy.

Parameters:

nearEvictPlc - Near eviction policy.

Returns:

this for chaining.

getNearEvictionPolicyFactory

@Nullable
public @Nullable javax.cache.configuration.Factory<EvictionPolicy<? super K,? super V>> getNearEvictionPolicyFactory()

Gets cache eviction policy factory. By default, returns null which means that evictions are disabled for cache.

Returns:

Cache eviction policy or null if evictions should be disabled.

setNearEvictionPolicyFactory

public NearCacheConfiguration<K,V> setNearEvictionPolicyFactory(@Nullable
                                                                @Nullable javax.cache.configuration.Factory<? extends EvictionPolicy<? super K,? super V>> nearEvictPlcFactory)

Sets cache eviction policy factory. Note: Eviction policy factory should be Serializable.

Parameters:

nearEvictPlcFactory - Cache expiration policy.

Returns:

this for chaining.

getNearStartSize

public int getNearStartSize()

Gets initial cache size for near cache which will be used to pre-create internal hash table after start. Default value is defined by CacheConfiguration.DFLT_NEAR_START_SIZE.

Returns:

Initial near cache size.

setNearStartSize

public NearCacheConfiguration<K,V> setNearStartSize(int nearStartSize)

Start size for near cache. This property is only used for CacheMode.PARTITIONED caching mode.

Parameters:

nearStartSize - Start size for near cache.

Returns:

this for chaining.

toString

public String toString()

Overrides:

toString in class Object
