我一直在嘗試使用Elasticsearch作爲替代Memcached的替代品。我已經安裝了memcached傳輸，它看起來很好，並且在正確的端口上。但是，如果我嘗試使用java spy.memcahed客戶端庫，我無法緩存東西。Elasticsearch作爲Memcached的替代品
相反，我得到這樣的錯誤：
2014-10-01 08:22:31.579 INFO net.spy.memcached.MemcachedConnection: Added {QA sa=localhost/127.0.0.1:11211, #Rops=0, #Wops=0, #iq=0, topRop=null, topWop=null, toWrite=0, interested=0} to connect queue

java.io.IOException: Disconnected unexpected, will reconnect.
一遍又一遍。
在Elasticsearch方面我得到的
[2014-10-01 08:22:31,675][ERROR][memcached.netty ] [Living Hulk] Unsupported opcode [0x2], ignoring and closing connection
這裏的錯誤是我的客戶端配置：
ConnectionFactoryBuilder factory = new ConnectionFactoryBuilder();
factory.setProtocol(ConnectionFactoryBuilder.Protocol.BINARY);
SerializingTranscoder t = new SerializingTranscoder(1000000);
t.setCompressionThreshold(1024);
factory.setTranscoder(t);
factory.setOpTimeout(1000);
factory.setTimeoutExceptionThreshold(1998);
factory.setHashAlg(DefaultHashAlgorithm.KETAMA_HASH);
factory.setLocatorType(ConnectionFactoryBuilder.Locator.CONSISTENT);
factory.setFailureMode(FailureMode.Redistribute);
factory.setUseNagleAlgorithm(false);
哇，只是想說，我從來沒有想過使用ElasticSearch到目前爲止： - } – Ashalynd 2014-10-02 01:44:00
