Topic

The MQTT Publisher destination writes messages to a single topic on the MQTT broker. Any MQTT client subscribed to that topic receives the messages. A topic is a string that the broker uses to filter messages for each connected client.

When you configure the destination, you define the topic name. You can include multiple topic levels in a topic. For example, the following topic has three topic levels:

sales/US/NorthernRegion

You cannot use MQTT wildcards in the topic name used by the MQTT Publisher destination.

For more information, see the HiveMQ documentation on MQTT topics.
