Selecting parts of a Flow with Select Flow

When you are working with complex flows you may want to use different elements from different parts or branches of the flow together.

Rulex provides a task, called Select Flows from which this operation can be performed.

For example, you may have different branches in a flow: one used to train the model, and a second one used for scoring. The first branch may be executed on a monthly basis, while the second scoring branch on a daily basis. You can import the training branch into the scoring flow and use the Select Flows task to merge the two branches exactly as you require, taking elements, such as datasets, clusters and rules, from the required task.

Prerequisites

Procedure

  1. Drag the Select Flows task onto the stage.

  2. Connect the tasks whose elements you want to use to the new task.

  3. Double click the Select Flows task.

  4. Configure the options described in the Select Flows options table below.

  5. Save and compute the task.
