+# Redis Connector
+
+This connector provides sinks that can request document actions to an
+[Redis](https://redis.io/). To use this connector, add the following 
+dependencies to your project:
+
+<table class="table table-bordered">
+  <thead>
+    <tr>
+      <th class="text-left">Redis version</th>
+      <th class="text-left">Maven Dependency</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+        <td>7.x</td>
+        <td>{{< connector_artifact flink-connector-redis-streams 3.0.0 >}}</td>
+    </tr>
+  </tbody>
+</table>
+
+{{< py_download_link "redis" >}}
+
+Note that the streaming connectors are currently not part of the binary
+distribution. See [here]({{< ref "docs/dev/configuration/overview" >}}) for information
+about how to package the program with the libraries for cluster execution.
