Virtual Record Generator¶

This stage generates new records based on the specified conditions. The functions of this stage include:

Generating required records by fixed triggering frequency (multiple frequency options).
Determining the dataset to be generated for the specific device and point, i.e., Map<assetId,Set<pointId>>, based on the filtering conditions (such as model IDs and asset tags).
Based on the above dataset, simulate triggering point data according to fixed technical frequency.

Configuration¶

The configuration tabs for this stage are General and Output.

Name	Required?	Description
Name	Yes	The name of the stage.
Description	No	The description of the stage.
Stage Library	Yes	The streaming operator library to which the stage belongs.
On Record Error	Yes	The processing method for error data. Discard: Error data will be discarded and ignored Send to Error: Error messages will be reported Stop Pipeline: The pipeline will be stopped

Name	Required?	Description
Generate Type	Yes	Select the method to generate new records. By ModelIDs：Match measurement points by model IDs By Asset Tags：Match measurement points by asset tags
Trigger Frequency	Yes	Specify the triggering frequency for generating records. Options are: 1 Second 10 Seconds 30 Seconds 1 Minute 5 Minutes 10 Minutes 30 Minutes
Mode	No	When the By ModelIDs method is selected, specify the model ID. In the Output Point field, specify the measurement point for the generated data records, using the format {modelId}::{pointId}.
AssetTag Key::Value	No	When the By Asset Tags method is selected, specify the asset tag key and value. In the Output Point field, specify the measurement point for the generated data records, using the format {modelId}::{pointId} or {pointId}.
Output Point	Yes	Specify the measurement point for the generated data records, using the format {modelId}::{pointId}.

The output results of this stage are the generated records, which include the following:

Common fields (such as assetId, pointId, modelId, time, and value). The value field has no practical meaning, and its value is 0.
