Enrich a data stream by dynamically adding fields based on user-provided static metadata configuration.

---

Description

The Static Metadata Enricher is designed to enrich a data stream by dynamically adding fields based on user-provided metadata configuration. Users can specify static properties, and the processor will process each event, adding fields according to the provided key-value pairs. The output strategy is determined dynamically based on the provided metadata. For added convenience, users also have the option of uploading a CSV file with metadata information.

Configuration

For each metadata entry, configure the following three options:

• Runtime Name: A unique identifier for the property during runtime.
• Value: The value associated with the property.
• Data Type: The data type of the property value.

Using CSV Option

Alternatively, you can utilize the CSV upload feature by creating a CSV file with the following format:

Runtime Name,Runtime Value,Data Type
sensorType,Temperature,String
maxSensorValue,100.0,Float
minSensorValue,0,Float

Example

Input Event

{
  "reading": 25.5
}

Output Event

{
  "reading": 25.5,
  "sensorType": "Temperature",
  "maxSensorValue": 100.0,
  "minSensorValue": 0.0
}
