具说大数据量，用这个不错。
memcache java 客户端 api。地址：http://www.danga.com/memcached/apis.bml ，有种客户端，我这使用 Dustin Sallings 版的（已经在 google code 了 http://code.google.com/p/spymemcached/）。

spymemcached 的下载地址：http://spymemcached.googlecode.com/files/memcached-2.2.jar 它依赖 spy.jar，spy.jar的下载地址：http://bleu.west.spy.net/~dustin/repo/spy/jars/spy-2.4.jar

把两个jar放到classpath下，然后写代码试用下：写入

package com.chenlb.use;

import java.io.IOException;
import java.io.Serializable;
import java.net.InetSocketAddress;
import java.util.Date;

import net.spy.memcached.MemcachedClient;

public class MemcacheUse {

	private static class MyData implements Serializable {
		private static final long serialVersionUID = 1L;
		private long d = new Date().getTime();
		public String toString() {
			return "my data ["+d+"]";
		}
	}

	public static void main(String[] args) throws IOException {
		MyData myData = new MyData();

		MemcachedClient c=new MemcachedClient(new InetSocketAddress("localhost", 11211));
		// Store a value (async) for one hour

		c.set("someKey", 3600, myData);

		// Retrieve a value (synchronously).
		Object myObject=c.get("someKey");

		c.shutdown();

		System.out.println(myObject);

	}

}

读：主要是验证下，一小时后读是否有效。
