由于 8478595263 > 5000000000 的本地暂停，未将节点标记为关闭
Not marking nodes down due to local pause of 8478595263 > 5000000000
我在 kubernetes 中有 3 个节点的 cassandra 集群。
使用 bitnami/cassandra helm chart 部署了 cassandra。
一段时间后根据更多请求数出现错误

根据您在上面发布的日志条目，节点过载导致它们无响应。突变被丢弃，因为提交日志磁盘跟不上写入。
您需要查看集群的大小，因为您可能需要添加更多节点以增加容量。干杯！
从上面的 "tpstats" 指标来看，指标看起来不错，但我们可以看到那里有一些变化，这表明您的集群正在过载。一些请求也在那里被阻止。提交日志似乎不接受那里的写入。您应该计划集群扩展或开始调试节点超载的原因。
