# MiddleManager Process
|
|
|
|
### Configuration
|
|
|
|
For Middlemanager Process Configuration, see [Indexing Service Configuration](../configuration/index.html#middlemanager-and-peons).
|
|
|
|
### HTTP Endpoints
|
|
|
|
For a list of API endpoints supported by the MiddleManager, please see the [API reference](../operations/api-reference.html#middlemanager).
|
|
|
|
### Overview
|
|
|
|
The MiddleManager process is a worker process that executes submitted tasks. Middle Managers forward tasks to Peons that run in separate JVMs.
|
|
The reason we have separate JVMs for tasks is for resource and log isolation. Each [Peon](../design/peons.html) is capable of running only one task at a time, however, a MiddleManager may have multiple Peons.
|
|
|
|
### Running
|
|
|
|
```
|
|
org.apache.druid.cli.Main server middleManager
|
|
```
