JEDIS带有AWS Elasticache(Redis)上的保存命令

Question

以下来自AWS中的tomcat服务器，我们有redis Elasticache实例设置：

redis.clients.jedis.exceptions.JedisDataException: ERR unknown command 'SAVE'
at redis.clients.jedis.Protocol.processError(Protocol.java:127)
at redis.clients.jedis.Protocol.process(Protocol.java:161)

似乎Elasticache缺少对此类命令的支持，因为Redis本身确实支持它。任何想法或解决方法都将不胜感激

ps1：jedis v2.9.0和Elasticache实例具有引擎版本兼容性：3.2.4

ps2：我只是向AWS支持提出了同样的问题，因为可悲的是我在这里根本没有反馈：（

您是否看过Redisson？AWS Elasticache SAVE命令中的某些redis命令是其中之一。这是此类命令的完整列表。尽管有这种局限性，Redisson与AWS Elasticache具有牢固的整合。

这是一个与AWS Elasticache一起使用的代码示例：

// 1. Create config object
Config config = new Config();
config.useReplicatedServers()
    .addNodeAddress("redis://first-node.aws.com:7000", "redis://second-node.aws.com:7001");
// 2. Create Redisson instance
RedissonClient redisson = Redisson.create(config);
// 3. Get object you need
RMap<MyKey, MyValue> map = redisson.getMap("myMap");
RLock lock = redisson.getLock("myLock");
RExecutorService executor = redisson.getExecutorService("myExecutorService");
// over 30 different objects and services are available...
