Package com.yahoo.vespa.filedistribution

Class FileDistributionConnectionPool

java.lang.Object

com.yahoo.vespa.config.JRTConnectionPool

com.yahoo.vespa.filedistribution.FileDistributionConnectionPool

All Implemented Interfaces:

com.yahoo.vespa.config.ConnectionPool, AutoCloseable

public class FileDistributionConnectionPool
extends com.yahoo.vespa.config.JRTConnectionPool

A pool of JRT connections to a set of file distribution source (one or more config servers). Used by file distribution clients, where the source that can serve a file reference might be different for each file reference (unlike config requests, where all requests should be served by the same source). A new connection is chosen randomly when calling {#link switchConnection(Connection failingConnection)}. Unlike JRTConnectionPool there is no state that holds the 'current' connection, a new connection is picked randomly if getCurrent() is called.
