What is Jedis?

Jedis is a Java client for Redis designed for performance and ease of use.

Contributing

We'd love your contributions!

Bug reports are always welcome! You can open a bug report on GitHub.

You can also contribute documentation -- or anything to improve Jedis. Please see contribution guideline for more details.

Getting started

To get started with Jedis, first add it as a dependency in your Java project. If you're using Maven, that looks like this:

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>4.2.0</version>
</dependency>

Next, you'll need to connect to Redis. For many applications, it's best to use a connection pool. You can instantiate a Jedis connection pool like so:

JedisPool pool = new JedisPool("localhost", 6379);

With a JedisPool instance, you can use a try-with-resources block to get a connection and run Redis commands.

Here's how to run a single SET command within a try-with-resources block:

try (Jedis jedis = pool.getResource()) {
  jedis.set("clientName", "Jedis");
}

Jedis instances implement most Redis commands. See the Jedis Javadocs for the complete list of supported commands.

Easier way of using connection pool

Using a try-with-resources block for each command may be cumbursome, so you may consider using JedisPooled.

JedisPooled jedis = new JedisPooled("localhost", 6379);

Now you can send commands like sending from Jedis.

jedis.sadd("planets", "Venus");

Connecting to a Redis cluster

Jedis lets you connect to Redis Clusters, supporting the Redis Cluster Specification. To do this, you'll need to connect using JedisCluster. See the example below:

Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7379));
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7380));
JedisCluster jedis = new JedisCluster(jedisClusterNodes);

Now you can use the JedisCluster instance and send commands like you would with a standard pooled connection:

jedis.sadd("planets", "Mars");

Using Redis modules

Jedis provides support for some of the Redis modules, most notably RedisJSON and RediSearch.

See the [RedisJSON Jedis](docs/redisjson.md) or [RediSearch Jedis](docs/redisearch.md) for details.

Documentation

The Jedis wiki contains several useful articles for using Jedis.

You can also check the latest Jedis Javadocs.
