Class RoundRobinMemcacheClient

java.lang.Object

com.spotify.folsom.AbstractRawMemcacheClient

com.spotify.folsom.client.AbstractMultiMemcacheClient

com.spotify.folsom.roundrobin.RoundRobinMemcacheClient

All Implemented Interfaces:

ConnectionChangeListener, ObservableClient, RawMemcacheClient

public class RoundRobinMemcacheClient
extends AbstractMultiMemcacheClient

A client that tries to distribute requests equally to all delegate clients. This would typically only make sense if all the delegates are pointing to the same host/port which might be a reasonable thing to do if the IO operations is a bottleneck.
