amazon-web-services - AWS Elasticsearch CPU使用率飙升

Question

我正在使用可以在v1.5集群上正常运行的AWS ElasticSearch，并将整个配置(分片，节点，实例类型，映射，数据)复制到新的v2.3集群。

当我将DNS指向新的v2.3群集时，CPU使用率会产生峰值，从而降低了整个应用程序的速度。当我在v1.5集群中运行时，CPU使用率几乎是线性的，约占CPU使用率的20％。

Obs:集群配置是相同的，三重检查!

亚马逊支持告诉我们这是一个v2.3错误，该错误修复将尽快发布...

但是我在发行说明中没有发现关于该错误的任何信息!

有小费吗？

Answer 1

我认为该错误仅存在于AWS Elasticsearch中。阅读来自AWS Support的以下消息:

Hello, Thank you for updating the case. After further investigation, looks like the ES 2.3 version has a bug which causes a CPU spike. An edge case was identified resulting in steady CPU spike. This has been fixed and the service team is rolling out patch. The issue should be resolved soon. I do not have a specific ETA as the release depends on a different team.
