Apache Ignite近缓存始终未命中

当使用近缓存时，一切都会正常工作，直到第二个客户端在缓存操作过程中尝试连接或断开与集群的连接

在第二个客户端连接/断开连接后，原始客户端将始终错过近缓存，直到原始客户端重新启动。几乎就像集群通知客户他们的问题，并将集群作为真相的来源

我们已经能够通过运行测试并连接/断开visor来重现这一点。在断开连接的过程中，我们可以看到原始客户端IgniteTxManager$NodeFailureTimeoutObject上的日志中提到的超时

下面是org.apache.ignite.internal.processors被抑制的日志片段

我的问题是，这是预期的行为吗？我们是否可以不绕过近缓存，或者在坏客户端断开连接后使用近缓存重新建立。事实证明，这是近缓存的一个错误。当发生拓扑更改时，它可以清除近缓存GridEntry上的拓扑版本，这将导致每次调用要检查条目是否有效，请返回false

Bug已提交

如何确定客户端在近缓存中发生了哪些未命中事件，以及数据是从数据节点加载的？@NikolayTikhonov我们设置了一个测试来判断性能，该测试将测量每次调用的时间并进行报告。我们一贯认为坏客户端不应影响其他客户端上的近缓存。可能，您有经常更改拓扑结构。您可以共享客户端节点的完整日志吗？@NikolayTikhonov，我更新了问题的更多细节和一些日志。我们必须针对类别，所以请告诉我是否应该在其他区域查找。
