General development of Jedis client in "Redis" Redis cluster and non-clustered environment

Under non-clustered environment

Set (" Chiwei "," lining "); System.out.println (Shardedjedis.getshard ("Chiwei"). Get ("Chiwei"));}}

The purpose of the Shard Shard is to distribute the data evenly across multiple Redis instances

The above test examples are simple key-value, try the complex key below

List

Shardedjedis.lpush ("Chiwei", "one"), Shardedjedis.lpush ("Chiwei", "one"), Shardedjedis.lpush ("Chiwei", "three"); Shardedjedis.lpush ("Chiwei", "three"); System.out.println (Shardedjedis.llen ("Chiwei")); String str = shardedjedis.lpop ("Chiwei"); System.out.println (str);

The list adds elements that can be repeated

Set cannot be duplicated

Shardedjedis.sadd ("Chiwei", "one"), Shardedjedis.sadd ("Chiwei", "one");

All other types, please try it yourself, http://www.redis.cn/commands.html
