Package org.elasticsearch.transport.netty4

Class Netty4Transport

java.lang.Object
org.elasticsearch.common.component.AbstractLifecycleComponent
org.elasticsearch.transport.TcpTransport
org.elasticsearch.transport.netty4.Netty4Transport
All Implemented Interfaces:
Closeable, AutoCloseable, org.elasticsearch.common.component.LifecycleComponent, org.elasticsearch.core.Releasable, org.elasticsearch.transport.Transport
public class Netty4Transport extends org.elasticsearch.transport.TcpTransport
There are 4 types of connections per node, low/med/high/ping. Low if for batch oriented APIs (like recovery or batch) with high payload that will cause regular request. (like search or single index) to take longer. Med is for the typical search / single doc index. And High for things like cluster state. Ping is reserved for sending out ping requests to other nodes.
