Package org.apache.druid.guice

Class RouterProcessingModule

java.lang.Object

org.apache.druid.guice.RouterProcessingModule

All Implemented Interfaces:

com.google.inject.Module

public class RouterProcessingModule
extends Object
implements com.google.inject.Module

This module is used to fulfill dependency injection of query processing and caching resources: buffer pools and thread pools on Router Druid node type. Router needs to inject those resources, because it depends on QueryToolChests, and they couple query type aspects not related to processing and caching, which Router uses, and related to processing and caching, which Router doesn't use, but they inject the resources.
