标签： c# apache caching configuration ignite

我正在使用Apache Ignite ver2.7，通过Config.xml设置启动Ignite服务器。

./ignite.sh $IGNITE_HOME/config/config.xml -J-Xms15g -J-Xmx17g

config.xml包含

<property name="dataStorageConfiguration">
        <bean class="org.apache.ignite.configuration.DataStorageConfiguration">
            <property name="defaultDataRegionConfiguration">
                <bean class="org.apache.ignite.configuration.DataRegionConfiguration">
                    <property name="persistenceEnabled" value="true"/>
                    <property name="name" value="Default_Region"/>
                    <property name="maxSize" value="#{15L * 1024 * 1024 * 1024}"/>

                    <property name="initialSize" value="#{10L * 1024 * 1024 * 1024}"/>
                   <property name="pageEvictionMode" value="RANDOM_2_LRU"/>
                </bean>
            </property>
        </bean>
    </property>

现在点燃开始给予

并与在dotnet应用程序中使用以下c＃代码创建的客户端连接

 if (igniteClient == null)
  {
   var client = new IgniteClientConfiguration
    {
      Host = IP
    };
    igniteClient = Ignition.StartClient(client);
    for(int i=0;i<n;i++)
    {
      igniteClient.GetOrCreateCache<int, HISTORICALDATAWithOHLC>(CacheConf);
/*HISTORICALDATAWithOHLC is a structure of OHLC*/
    }
 }

和 创建多个缓存后创建多个缓存... 客户端崩溃。

我在互联网上搜索并获得了Ignite official website 

<bean class="org.apache.ignite.configuration.CacheConfiguration">
...
<!-- Enable swap. -->
<property name="swapEnabled" value="true"/> 
...
</bean>

通过此设置点燃服务器无法启动

我申请了

var cacheCfg = new CacheConfiguration
{
   EnableSwap = true
};

此代码为我的C＃代码，但EnableSwap属性不存在

我想要的是-

如果堆上和堆外内存已满，则条目将逐出到磁盘，而堆上和堆外内存将在此处管理新条目的空间。

1 个答案:

答案 0 :(得分：1)

如果启用了持久性，则Ignite将自动将数据从内存中逐出到磁盘，您无需配置pageEvictionMode属性。

关于您所拥有的异常，我认为从异常消息中可以很清楚地了解到

  

未配置请求的DataRegion：defaultRegion

就像在CacheConfiguration中，您选择了错误的区域名称（因为您更改了默认区域的名称）。如果仅使用一个默认区域，则只需删除该区域的名称，而根本不为缓存配置区域名称。
