先附:这里说高,是指的对于我们应用来说,学生党能省则省
数据量在 10GB,查询访问峰值低于 10 QPS,查询速度最好低于 100ms,系统负载应低于 3
现在需要单独购买一个阿里云服务器示例,用来跑 Elasticsearch, 用什么配置最合适?
1 核心 1GB 内存 20GB 数据盘可以吗?

能省则省的话不是应该挑国外便宜的主机吗

ES官方推荐的最佳配置是64GB,http://www.elastic.co/guide/en/elasticsearch/guide/current/hardware.html
A machine with 64 GB of RAM is the ideal sweet spot, but 32 GB and 16 GB machines are also common. Less than 8 GB tends to be counterproductive (you end up needing many, many small machines), and greater than 64 GB has problems that we will discuss in Heap: Sizing and Swapping. |

一直用128G的机器跑Es

用48G跑ES表示鸭梨很大

ES毕竟是基于JVM之上的,1G内存有点捉急吧
