A zero-load node is a control node, which only supports dry-run scheduling and does not generate any data. It usually serves as the root node of a workflow.

Note You can configure an output table for a zero-load node so that the output table can be used as an input table of another node. However, the zero-load node does not process the table data.
  1. Log on to the DataWorks console. In the left-side navigation pane, click Workspaces. On the Workspaces page, find the target workspace and click Data Analytics in the Actions column.
  2. Move the pointer over the Create a zero-load node icon and choose General > Zero-Load Node.

    You can also click a workflow, right-click General, and then choose Create > Zero-Load Node.

  3. In the Create Node dialog box, configure Node Name and Location and click Commit.
    Note The node name must be 1 to 128 characters in length.
  4. Skip editing the node code. You do not need to edit code for zero-load nodes.
  5. Configure the node schedule.

    Click Properties on the right and set the relevant parameters in the Schedule section. For more information, see Properties.

  6. Commit the node.

    After the schedule configuration is completed, click the Save icon and then the Submit or Commit and Unlock icon in the top toolbar of the code editor. The zero-load node is committed to the development environment.

  7. Deploy the node.

    For more information, see Deploy a node.

  8. Test the node in the production environment.
