Adding kernels to the graph

A graph can include multiple kernels connected with each other in the order they will be executed within the process at runtime. You add kernels to the graph from the library of predefined kernels, from your workspace, and from the external storage.

To add an APEX2 kernel to the graph:

  1. Open the graph diagram. In the Palette pane, drag Add Kernels from the Palette (Kernel Definition section) and drop it to the canvas.

  2. To find a certain kernel, use the filtering button to specify the kernel location, or start typing the kernel name in the search box. The following wildcards are supported:
    • ? matches any character in a specific position
    • * matches any set of characters, including the empty string

    These wildcard characters can be used in combination.

  3. Select the required kernel, then click OK.
  4. Connect the Input and Output elements with the respective kernel ports. To connect two elements on the canvas, click the Connector element in the Palette pane, then click the element from which data will be transmitted, and then the element to which data will be forwarded. Press and hold the Ctrl key to add several connectors.
