Question

我遇到了GCP Bigtable Python客户端的问题，它偶尔会丢失与Bigtable的连接并导致服务器错误。

错误消息附在下面。当我尝试写Bigtable时会发生这种情况。我还观察到，当服务器暂时处于非活动状态时，这个问题往往会更频繁地发生。

有没有人有类似的经历？这是Bigtable Python Client中的已知错误吗？

Answer 1

这似乎已在https://github.com/googleapis/google-cloud-python/issues/2683中修复。

鉴于这是一个非常老的问题，我认为较新的版本应该已经解决了这个问题。

Answer 2

到目前为止，我处理此问题的解决方案是在失败时进行手动重试。它对我们有用，因为问题不经常发生。此外，它似乎不是0.28.1版本中的问题
