Jedis

Jedis is a blazingly small and sane Redis java client.

Jedis was conceived to be EASY to use.

Jedis is fully compatible with redis 2.8.5.

So what can I do with Jedis?

All of the following redis features are supported:

• Sorting
• Connection handling
• Commands operating on any kind of values
• Commands operating on string values
• Commands operating on hashes
• Commands operating on lists
• Commands operating on sets
• Commands operating on sorted sets
• Transactions
• Pipelining
• Publish/Subscribe
• Persistence control commands
• Remote server control commands
• Connection pooling
• Sharding (MD5, MurmurHash)
• Key-tags for sharding
• Sharding with pipelining
• Scripting with pipelining
• Redis Cluster

How do I use it?

You can download the latest build at: http://github.com/xetorthio/jedis/releases

Or use it as a maven dependency:

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.6.0</version>
    <type>jar</type>
    <scope>compile</scope>
</dependency>

To use it just:

Jedis jedis = new Jedis("localhost");
jedis.set("foo", "bar");
String value = jedis.get("foo");

For more usage examples check the tests.

Please check the wiki. There are lots of cool things you should know, including information about connection pooling.

And you are done!

Jedis Cluster

Redis cluster specification (still under development) is implemented

Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
//Jedis Cluster will attempt to discover cluster nodes automatically
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7379));
JedisCluster jc = new JedisCluster(jedisClusterNodes);
jc.set("foo", "bar");
String value = jc.get("foo");

I want to contribute!

That is great! Just fork the project in github. Create a topic branch, write some code, and add some tests for your new code.

To run the tests:

• Use the latest redis master branch.

• Run make test. This will run 2 instances of redis. We use 2 redis servers, one on default port (6379) and the other one on (6380). Both have authentication enabled with default password (foobared). This way we can test both sharding and auth command. For the Sentinel tests to we use a default Sentinel configuration that is configured to properly authenticate using the same password with a master called mymaster running on 6379.

Thanks for helping!
