Apache Ignite 近缓存总是丢失
Apache Ignite Near Cache Always Missed
当使用近缓存时，一切都会正常工作，直到第二个客户端（可能是 visor）在缓存操作正在进行时尝试连接或断开连接到集群。
在第二个客户端connects/disconnects之后，原来的客户端总是会错过近缓存，直到原来的客户端重新启动。几乎就像集群通知客户他们的问题一样，并将集群作为真相的来源。
我们已经能够通过 运行 我们的测试和 connecting/disconnect 使用遮阳板重现这一点。在断开连接期间，我们可以看到原始客户端 IgniteTxManager$NodeFailureTimeoutObject 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？我们能否让近缓存不被绕过，或者至少在坏客户端断开连接后使用近缓存重新建立。
事实证明他们是附近缓存的错误。当发生拓扑更改时，它可以清除 NearCacheGridEntry 上的拓扑版本，这将导致每次调用都检查条目是否有效 return false。
当使用近缓存时，一切都会正常工作，直到第二个客户端（可能是 visor）在缓存操作正在进行时尝试连接或断开连接到集群。
在第二个客户端connects/disconnects之后，原来的客户端总是会错过近缓存，直到原来的客户端重新启动。几乎就像集群通知客户他们的问题一样，并将集群作为真相的来源。
我们已经能够通过 运行 我们的测试和 connecting/disconnect 使用遮阳板重现这一点。在断开连接期间，我们可以看到原始客户端 IgniteTxManager$NodeFailureTimeoutObject 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？我们能否让近缓存不被绕过，或者至少在坏客户端断开连接后使用近缓存重新建立。
事实证明他们是附近缓存的错误。当发生拓扑更改时，它可以清除 NearCacheGridEntry 上的拓扑版本，这将导致每次调用都检查条目是否有效 return false。
