<p>Today we added connectivity to <a href="https://kafka.apache.org/">Apache Kafka</a>. In a first step, it is possible to publish
<em>twin events</em>, <em>messages</em>, <em>live commands and events</em> to Kafka topics.</p>
<p>Since the last addition to Ditto’s connectivity which <a href="2018-10-16-example-mqtt-bidirectional.html">added MQTT connectivity</a>,
the connectivity feature got a lot of stabilization and new smaller features, e.g. the recent addition of
<a href="basic-placeholders.html#function-expressions">placeholder functions</a>.</p>
<p>Returning to the Kafka integration Ditto can now, for example, whenever a <a href="intro-digitaltwins.html">digital twin</a> is
changed (e.g. a device updated some state data), publish a <em>twin event</em> to a Kafka topic.</p>
<p>If you already rely on Apache Kafka as a source for your data lake or analytics, integrating Ditto and its digital twins
is now super easy.</p>
<p>Find out more at our <a href="connectivity-protocol-bindings-kafka2.html">Kafka documentation</a>.</p>
