Jedis Cluster setex() Method: Setting Keys with Expiration in Redis

JedisCluster.setex() is a method used to set the value of a key in a Redis Cluster with an expiration time.

Syntax:

jedisCluster.setex(key, seconds, value)

Parameters:

• 'key': The key to be set.
• 'seconds': The expiration time in seconds.
• 'value': The value to be set for the key.

Return Value:

The method returns 'OK' if the key was set successfully.

Example:

import redis.clients.jedis.*;

public class RedisClusterExample {
    public static void main(String[] args) {
        // Creating a Jedis Cluster object
        JedisCluster jedisCluster = new JedisCluster(new HostAndPort("localhost", 6379));

        // Setting a key-value pair with an expiration time of 60 seconds
        String key = "myKey";
        int expirationTimeInSeconds = 60;
        String value = "myValue";
        jedisCluster.setex(key, expirationTimeInSeconds, value);

        // Getting the value for the key
        String retrievedValue = jedisCluster.get(key);
        System.out.println("Retrieved value: " + retrievedValue);
        
        // Closing the Jedis Cluster connection
        jedisCluster.close();
    }
}

In the above example, we are setting a key 'myKey' with a value 'myValue' and an expiration time of 60 seconds using jedisCluster.setex method. We then retrieve the value using jedisCluster.get method and print it. Finally, we close the Jedis Cluster connection.
