Step 4: Route Selected Records

The checked-in reference sends each selected record to Kafka and a local file. The gateway remains outside Expanso's protocol boundary.

Reference configuration

  broker:
    outputs:
      - kafka:
          addresses: ['${KAFKA_BROKERS:localhost:9092}']
          topic: '${KAFKA_TOPIC:scada-review-events}'
      - file:
          path: '${LOCAL_ARCHIVE_PATH:/tmp/scada-review-events.jsonl}'
          codec: lines

The source artifact is examples/integrations/scada-energy-edge/step-4-route-destinations.yaml.

Required review

1. Define Kafka authentication, topic policy, ordering, retries, and backpressure.
2. Verify which fields may cross the site boundary.
3. Define local retention, file permissions, and disk-full behavior.
4. Exercise delivery and retention with representative, authorized inputs.

Current status

Neither destination has been exercised by repository evidence. Delivery behavior and failure recovery remain not assessed.

Next: Review the combined reference.
