Question

I v use LruEvictionPolicyFactory in my CacheConfiguration such as fire

CacheConfiguration<K, V> cacheCfg = new CacheConfiguration<>();
cacheCfg.setAtomicityMode(CacheAtomicityMode.ATOMIC);
cacheCfg.setRebalanceMode(CacheRebalanceMode.ASYNC);
cacheCfg.setPartitionLossPolicy(PartitionLossPolicy.READ_WRITE_SAFE);
cacheCfg.setWriteSynchronizationMode(CacheWriteSynchronizationMode.PRIMARY_SYNC);
cacheCfg.setEvictionPolicyFactory(new LruEvictionPolicyFactory<>(200000));

我使用数据

 <bean class="org.apache.ignite.configuration.DataRegionConfiguration">      
    <property name="initialSize" value="#{512L * 1024 * 1024}"/>
    <property name="maxSize" value="#{3 * 1024L * 1024 * 1024}"/>
    <property name="pageEvictionMode" value="RANDOM_LRU"/>
    <property name="evictionThreshold" value="0.9"/>
    <property name="metricsEnabled" value="true"/>
    <property name="persistenceEnabled" value="false"/>
 </bean>

但是,我可以看到,我藏匿的2000 000多份记录,有时甚至有800 000份记录。

你的数据区域配置似乎越来越正确,根据这个网址:page。我建议使用<条码>RANDOM_2_LRU,并没收一个数据区域名称供参考。

 <bean class="org.apache.ignite.configuration.DataRegionConfiguration">      
    <property name="initialSize" value="#{512L * 1024 * 1024}"/>
    <property name="name" value="region_name"/>
    <property name="maxSize" value="#{3 * 1024L * 1024 * 1024}"/>
    <property name="pageEvictionMode" value="RANDOM_LRU"/>
    <property name="evictionThreshold" value="0.9"/>
    <property name="metricsEnabled" value="true"/>
    <property name="persistenceEnabled" value="false"/>
 </bean>

页: 1 https://www.gridgain.com/sdk/latest/javadoc/org/apache/ignite/configuration/CacheConfiguration.html#setDataRegionName-java.lang.String-"rel=“nofollow noretinger” 例如:

CacheConfiguration<K, V> cacheCfg = new CacheConfiguration<>();
cacheCfg.setAtomicityMode(CacheAtomicityMode.ATOMIC);
cacheCfg.setRebalanceMode(CacheRebalanceMode.ASYNC);
cacheCfg.setPartitionLossPolicy(PartitionLossPolicy.READ_WRITE_SAFE);
cacheCfg.setWriteSynchronizationMode(CacheWriteSynchronizationMode.PRIMARY_SYNC);
cacheCfg.setDataRegionName("region_name");
