+
+This connector provides a sink that writes data into a
[Cassandra](https://cassandra.apache.org/) database.
+
+The Flink Cassandra sink integrates with Flink's checkpointing mechanism
to provide
+exactly-once processing semantics. To achieve that, Flink buffers incoming
records
+and commits them only when a checkpoint completes.
+
+To use this connector, add the following dependency to your project:
+
+{% highlight xml %}
+<dependency>
+ <groupId>org.apache.flink</groupId>
+ <artifactId>flink-connector-cassandra{{ site.scala_version_suffix
}}</artifactId>
+ <version>{{site.version }}</version>
+</dependency>
+{% endhighlight %}
+
+Note that the streaming connectors are currently not part of the binary
distribution. See how to link with them for cluster execution [here]({{
site.baseurl}}/apis/cluster_execution.html#linking-with-modules-not-contained-in-the-binary-distribution).

> Project: Flink
> Issue Type: Improvement
> Components: Streaming Connectors
> Reporter: Robert Metzger
> Assignee: Chesnay Schepler
>
> With FLINK-3311, we are adding a Cassandra connector to Flink.
> It would be good to also provide an "exactly-once" C* connector.
> I would like to first discuss how we are going to implement this in Flink.
