This video shows how to use the Request/Response MQTT 5 pattern, extract metadata from MQTT messages, such as response topic, correlation data and content type, enrich MQTT payloads with this metadata via an AWS IoT Rules Engine rule and store the enriched data in Amazon Dynamo DB.
The aim is to reduce custom code, therefore the native integration between IoT Rules Engine and Amazon DynamoDB is used.

The demo used in this video is building a simple Vehicle Command Log Store, to keep track of command requests and responses sent to vehicles from app clients.
