 #### Kafka endpoint is a data flow source
 
 > [!NOTE]
-> There's a known issue when using Event Hubs endpoint as a data flow source where Kafka header gets corrupted as its translated to MQTT. This only happens if using Event Hub though the Event Hub client which uses AMQP under the covers. For for instance "foo"="bar", the "foo" is translated, but the value becomes"\xa1\x03bar".

 When a Kafka endpoint is a data flow source, Kafka user headers are translated to MQTT v5 properties. The following table describes how Kafka user headers are translated to MQTT v5 properties.
