为什么有高纬度的间谍?
原标题:Why BigTable has high latency spikes?

We have two BigTable clusters joined into one instance. There is a bidirectional replication between these cluster. As I understand, replication is always bidirectional and it is not possible to make one-directional. There are two profiles:

  • first - for production, it reads and writes and requires low latency. This profile is routed to one cluster
  • second - for analytics. This profile reads big amounts of data and routed to another cluster.

此外,分析小组也有自动升级政策。 违约时有1个点,但当有较大负荷时,该点可扩大到10个点。

大部分时间生产组提供的相对较少。 但有时可能出现高强度的间谍。 似乎与第二组中高读活动有相关性(在活动负荷期间,集群活动可能达到100%,在扩大期间出现新的节点)。

问题:能否把我对另一个群体的影响力集中起来? 是否有任何办法处理这一问题?

问题回答

你们采用了什么样的路线政策? 如果你改用多组轮车,你的一些分析内容可能会打上你在职/生产组群。

如果你想进行分析,就只针对第二组,那么你就应当采用单一组别的路线政策。
