Package org.apache.druid.guice

Class BrokerProcessingModule

java.lang.Object

org.apache.druid.guice.BrokerProcessingModule

All Implemented Interfaces:

com.google.inject.Module

public class BrokerProcessingModule
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 Broker. Broker does not need to be allocated an intermediate results pool. This is separated from DruidProcessingModule to separate the needs of the broker from the historicals
