## MiddleManager进程
### 配置
对于Apache Druid MiddleManager配置可以参见[索引服务配置](../Configuration/configuration.md#MiddleManager)
### HTTP
对于MiddleManager的API接口详见 [MiddleManager API](../Operations/api.md#MiddleManager)
### 综述
MiddleManager进程是执行提交的任务的工作进程。MiddleManager将任务转发给运行在不同jvm中的Peon。我们为每个任务设置单独的jvm的原因是为了隔离资源和日志。每个Peon一次只能运行一个任务但是一个MiddleManager可能有多个Peon。
### 运行
```json
org.apache.druid.cli.Main server middleManager
```
