Who doesn't know about Redis? It's harder and harder to find someone giving a positive answer to this question as the popularity of this key/value store is constantly increasing. With an extensive support for diverse data structures, file-based persistence, a publish/subscribe engine and an upcoming (and highly anticipated) support for , it is indeed not surprising to find Redis running in more and more environments.

Therefore, we're happy to announce the first release of the Redis Connector for . Read on to see all the cool things Mule and Redis can do together…

Let's do a quick tour of the different features of the Redis Connector. You can find the complete user guide on Muleforge.


Connecting Mule to a local non-password protected Redis running on its standard port is as simple as:

Behind the scene, the connector relies on Jedis for protocol handling and connection pooling. The complete range of options, including the configuration of a custom pool, is shown hereafter:

With the connection established to Redis, it's now time to read and write data.

Data structure operations

The connector supports operations on Redis' stringshasheslistssets and sorted sets. The following showcases a few commands with some of their attributes shown:

Publish / Subscribe

Redis not only excels at data structures, it also offers a no-fluff pub/sub engine. Mule can both publish and subscribe to Redis channels, as demonstrated below:

Mule data persistence

Through the connector, Mule can directly leverage Redis to persist its internal data. In fact, components like the until-successful router or the PubSubHubbub module rely on the pluggable object store infrastructure that exists in Mule.

The following shows a (previously shown) example of until-successful modified to use Redis as its object store:

Give it a try

Add the MuleForge repository  to your POM file:

Then add the connector as a dependency:

Finally, add the redis namespace declarations in your Mule XML configuration file:

And off you go, your Mule is Redis-ready!

Missing something?

Redis exposes numerous operations on its different data structures: this first version of the Mule Connector doesn't expose them all. If you're missing one please let us know, either in a comment below or on GitHub.
