Redis

Redis is an open-source software project (sponsored by Redis Labs) that implements data structure servers. It is networked, in-memory, and stores keys with optional durability.

Maven Project

To use Redis driver in a Maven Project:

        <dependency>
            <groupId>org.jnosql.diana</groupId>
            <artifactId>redis-driver</artifactId>
            <version>version</version>
        </dependency>

E.g:

        <dependency>
            <groupId>org.jnosql.diana</groupId>
            <artifactId>redis-driver</artifactId>
            <version>0.0.1</version>
        </dependency>

Key Value

The Redis key-value implementation uses the RedisConfiguration to the configuration. This class has configurations methods such as host, port, timeout, user, password. Beyond the method also it can read a configuration from diana-redis.properties file.

• redis-master-host: the host client
• redis-master-port: the port, the default value 6379<
• redis-timeout: the redis timeout, the default value 2000 on milis
• redis-password: the password
• redis-database: the redis database number, the default value is 0
• redis-clientName: the redis client name
• redis-configuration-max-total: The max number of thread to {@link JedisPoolConfig}, the default value 1000
• redis-configuration-max-idle: The max idle {@link JedisPoolConfig}, the default value 10
• redis-configuration-min-idle: The min idle {@link JedisPoolConfig}, the default value 1
• redis-configuration-max--wait-millis: The max wait on millis on {@link JedisPoolConfig}, the default value 3000

Sample Code

public class App {


    public static void main(String[] args) {

        KeyValueConfiguration configuration = new ArangoDBKeyValueConfiguration();
        try (BucketManagerFactory managerFactory = configuration.get()) {
            BucketManager bucket = managerFactory.getBucketManager("bucket");
            List<String> list = managerFactory.getList("bucketList", String.class);
            Set<String> set = managerFactory.getSet("bucketSet", String.class);
            Map<String, Integer> map = managerFactory.getMap("bucketList", String.class, Integer.class);
            Queue<String> queue = managerFactory.getQueue("queueList", String.class);
            bucket.put("key", "value");
            Optional<Value> value = bucket.get("key");
        }


    }
}
