Multiple Data Sinks

The Databridge supports the configuration of multiple data sinks per route also including the transformation per sink. This allows for a flexible and powerful data routing mechanism, enabling users to direct data to various endpoints with specific transformations applied as needed.

Configuration

To configure multiple data sinks, you can define them in the routes.json file under the datasinks section. Each sink can have its own transformation rules, allowing for tailored data processing.

This is what an example configuration might look like for one route:

[
    {
        "datasource": "EnvironmentalSensorMQTT",
        "transformers": [
            "TemperatureTransformer",
            "HumidityTransformer",
            "AirQualityTransformer"
        ],
        "datasinks": [
            "TemperatureAAS",
            "HumidityAAS",
            "AirQualityAAS"
        ],
        "datasinkMappingConfiguration":
		{
			"TemperatureAAS": ["TemperatureTransformer"],
			"HumidityAAS": ["HumidityTransformer"],
			"AirQualityAAS": ["AirQualityTransformer"]
		},
        "trigger": "event"
    }
]

Working Example

You can find an example that you can try out yourself in the examples directory on our GitHub repository. This example demonstrates how to set up multiple data sinks with different transformations applied to each sink for a simple MQTT data source. Please follow the instructions in the README file of the example to run the scenario.
