MQTT source kamelet does not include topic

[florianluediger]

It is common for MQTT use cases to distribute data over multiple topics. You might have different subtopics for different devices for example. The MQTT source kamelet supports subscribing to multiple topics by using wildcards but the information about the topic is lost because the MQTT source only reports the body of the MQTT message to the sink. It would be great, if the topic could be included in the body that is reported to the sink.

Example:

You have multiple devices publishing to the topics:
/data/deviceId1
/data/deviceId2
...

The MQTT source is able to subscribe to the topic /data/# and it receives all messages. However, the information about which device sent the message is lost.

Nevermind, figured it out. For everyone else wondering: The topic is included in the header which is not displayed by the log sink by default.
