Topic Mappings

This section allows you to assign MQTT topics to pipelines. When a message is published to a mapped topic, the associated pipeline will be triggered.

What are Topic Mappings?​

Topic Mappings connect MQTT topics to data pipelines. A single topic can be mapped to multiple pipelines, allowing the same message to trigger different processing workflows.

MQTT Topic Patterns​

Topic mappings support MQTT wildcards:

  • Single-level wildcard (+): sensors/+/temperature matches sensors/device1/temperature
  • Multi-level wildcard (#): sensors/# matches all topics under sensors/

Use Cases​

Topic mappings enable flexible data routing:

  • Device-Specific Processing: Route different device types to specialized pipelines
  • Multi-Destination Data: Send the same data to multiple TagoIO instances
  • Topic-Based Filtering: Process only specific topics while ignoring others
