This topic guides you through the final steps of configuring the output for a Topic parsing task, building upon the output fields defined in the processing node.
Prerequisites
Ensure the source node is configured.
Background information
For an overview of the data parsing feature, refer to Usage Notes.
For guidance on navigating the data parsing workspace, see Data Parsing Workspace Instructions.
Procedure
In the middle canvas, click the add icon following the current node.
From the node list, single click Destination Node.
On the canvas, single click Destination Node, and in the Destination Node panel, select the Destination Type and configure its settings.
ImportantWhen Pass-through is set to Yes in the Format Parsing Source Node, the Target Type defaults to IoT Instance Topic and is not editable. For instructions on configuring the source node, see Configure the Source Node.
Destination Type
Description
IoT Instance Topic
Choose the Product and specify the Destination Topic.
Selection is limited to products and their custom topics within the current instance.
The panel displays the Output Data Format set in the preceding node.
IoT Instance Custom Storage Table
Select an existing Custom Storage Table.
If no custom storage table exists, create one first. For details, see Create and manage custom storage tables.
This panel lists the output fields defined in the previous node.
ImportantIf the selected table is empty, the IoT Platform will automatically populate it with fields based on the output field definitions.
You can define the Metric Name, Unique Key, Data Type, Precision, Description, and other attributes as needed. Ensure these definitions align with the custom storage table's requirements.
If the table already has fields, the output fields must match existing fields in the custom storage table, including the primary key. If not, adjust the output fields in the preceding processing node to comply with the custom storage table's field requirements.
For more details, see Manage custom storage tables.
To view additional information about the output fields, visit the Dataservice Studio > Data Metric page. For more information, see Data Metric Overview.
To finalize, single click Save at the top right corner of the Data Parsing Workbench.
NoteWhen using an API data source, ensure to add a field named ts in the node preceding the destination node, representing the Unix millisecond timestamp of data generation.
What to do next
Once the destination node is configured, proceed to debug and publish the data parsing task. For guidance, see Start data parsing task.
