What is Jedis?

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

Are you looking for a high-level library to handle object mapping? See redis-om-spring!

Supported Redis versions

The most recent version of this library supports redis version 5.0, 6.0, 6.2, 7.0 and 7.2.

The table below highlights version compatibility of the most-recent library versions and Redis versions. Compatibility means communication features, and Redis command capabilities.

Jedis version Supported Redis versions JDK Compatibility
3.9+ 5.0 and 6.2 Family of releases 8, 11
>= 4.0 Version 5.0 to current 8, 11, 17
>= 5.0 Version 6.0 to current 8, 11, 17

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:


To use the cutting-edge Jedis, check here.

Next, you'll need to connect to Redis. Consider installing a redis-stack docker:

docker run -p 6379:6379 -it redis/redis-stack:latest

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 cumbersome, 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("", 7379));
jedisClusterNodes.add(new HostAndPort("", 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 includes support for Redis modules such as RedisJSON and RediSearch.

See the RedisJSON Jedis or RediSearch Jedis for details.


Jedis supports retry and failover for your Redis deployments. This is useful when:

  1. You have more than one Redis deployment. This might include two independent Redis servers or two or more Redis databases replicated across multiple active-active Redis Enterprise clusters.
  2. You want your application to connect to one deployment at a time and to fail over to the next available deployment if the first deployment becomes unavailable.

For the complete failover configuration options and examples, see the Jedis failover docs.


The Jedis wiki contains several useful articles for using Jedis.

You can also check the latest Jedis Javadocs.

Some specific use-case examples can be found in redis.clients.jedis.examples package of the test source codes.
