## Modules
As of Druid v0.6, most core Druid functionality has been compartmentalized into modules. There are a set of default modules that may apply to any node type, and there are specific modules for the different node types. Default modules are __lazily instantiated__. Each module has its own set of configuration. This page will describe the configuration of the default modules.

There are a set of default modules that may apply to any node type, and there are specific modules for the different node types. Default modules are __lazily instantiated__. Each module has its own set of configuration.
This page describes the configuration of the default modules. Node-specific configuration is discussed on each node's respective page. In addition, you can add custom modules to [extend Druid](Modules.html).
Configuration of the various modules is done via Java properties. These can either be provided as `-D` system properties on the java command line or they can be passed in via a file called `runtime.properties` that exists on the classpath.
