### Configuration
|
|
|
|
For Apache Druid Peon Configuration, see [Peon Query Configuration](../configuration/index.md#peon-query-configuration) and [Additional Peon Configuration](../configuration/index.md#additional-peon-configuration).
|
|
|
|
For basic tuning guidance for MiddleManager tasks, see [Basic cluster tuning](../operations/basic-cluster-tuning.md#task-configurations).
|
|
|
|
### HTTP endpoints
|
|
|
|
For a list of API endpoints supported by the Peon, please see the [Peon API reference](../operations/api-reference.md#peon).
|
|
|
|
Peons run a single task in a single JVM. MiddleManager is responsible for creating Peons for running tasks.
|
|
Peons should rarely (if ever for testing purposes) be run on their own.
|
|
|
|
### Running
|
|
|
|
The Peon should very rarely ever be run independent of the MiddleManager unless for development purposes.
|
|
|
|
```
|
|
org.apache.druid.cli.Main internal peon <task_file> <status_file>
|
|
```
|
|
|
|
The task file contains the task JSON object.
|
|
The status file indicates where the task status will be output.
