Ignite 点燃C++；客户端模式，近缓存

我有一个在复制模式下运行的ignite服务器，在同一个节点上有许多启用了近缓存的客户端。现在，当我使用近缓存和不使用近缓存运行客户机时，我没有发现有显著的性能差异

我对近缓存的理解是，经常使用的键和值将存储在客户机本身，因此不会对服务器进行实际的Get（）调用。如果我错了，请纠正我

是否有人可以共享正在工作的近缓存配置xml

是的，near-cache通过在本地缓存节点上经常使用的条目来提高性能，但如果在单机或JVM上运行所有测试，这是没有意义的。近缓存允许不在远程节点上获取数据，但在您的测试中，一切都已在本地工作

此外，近缓存对

复制的

或

分区的

缓存上的服务器节点没有意义，其中备份的数量等于或大于数据节点的数量，因为每个节点的所有数据集都已在本地可用

所以，为了提高性能，当服务器节点在远程机器上工作时，您需要将客户端节点配置为使用近缓存。测量前，不要忘记在缓存附近预热

以下是用于设置近缓存的XML代码段：

...
<bean class="org.apache.ignite.configuration.CacheConfiguration">

       <!-- Your other cache config -->

       <property name="nearConfiguration">
             <bean class="org.apache.ignite.configuration.NearCacheConfiguration"/>
       </property>
</bean>
...

。。。

我已经添加了使用过的配置，但是使用上面的配置，我可以看到ignitevisor关闭了近缓存。我想您看到的节点是错误的。它可能对服务器禁用，但对客户端启用。您好，谢谢，我可以看到我没有为每个缓存单独添加近缓存配置。现在我可以看到近缓存已启用。。
