No he podido encontrar un buen tutorial sobre Memcached en Amazon Cloudand y soy muy nuevo en todo este proceso de almacenamiento en caché. Estoy tratando de usar memcached a través del servicio ElastiCache de Amazon y con un cliente spymemcached para hacer realmente las llamadas memcached.Configuración de Amazon ElastiCache con spymemcached en Java
Esto es lo que estoy haciendo en este momento de Java:
try {
ConnectionFactoryBuilder connectionFactoryBuilder = new ConnectionFactoryBuilder();
MemcachedClient memcachedClient = new MemcachedClient(
connectionFactoryBuilder.build(),
AddrUtil.getAddresses("<beginning of cache node end point grabbed from AWS Console>.cache.amazonaws.com:11211"));
memcachedClient.set("test", 12, new Integer(12));
System.out.println(memcachedClient.get("test"));
} catch (IOException ioException) {
ioException.printStackTrace();
}
El error que consigo cuando intento esto es:
java.net.ConnectException: Connection refused
