2.1.15版本,双DC的集群,读写策略是local_quorum,停掉备DC的所有节点,通过jmx监控到的写时延WriteLatency,从1毫秒上升到将近3毫秒,备DC服务启动后恢复,请问是什么原因?

差异可能是因为coordinator node正在为另一个发生故障的DC存储hints。

您可以在其他clusters中一致地复制吗? 差异太低而不必担心。

The difference may be because the coordinator node is storing hints for the other DC that is down.

Is it something you can replicate consistently in other clusters? The difference is too low to worry about. Cheers!
