MiddleManager Process

Configuration

For Apache Druid MiddleManager Process Configuration, see Indexing Service Configuration.

HTTP endpoints

For a list of API endpoints supported by the MiddleManager, please see the API reference.

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 is capable of running only one task at a time, however, a MiddleManager may have multiple Peons.

Running
