Workflow pipelines

You can add any number of processing pipelines to a workflow. Within the workflow, you can order your processing pipelines in any way you want. When a task runs for a workflow, documents pass through each pipeline in the workflow in sequential order.

For information on processing pipelines, see Processing pipelines and stages.

Adding pipelines to a workflow

You can add any existing processing pipeline to a workflow.

NoteYou cannot add a pipeline to a workflow more than once. If you need to run the same pipeline multiple times in a workflow, you can clone the pipeline and add the clone to the workflow. For information, see Cloning components.

All Preprocessing pipelines must precede all Workflow-Agent pipelines. For information, see Pipeline execution modes.

Reordering pipelines in a workflow

Documents pass through the pipelines in a workflow one after the other. When ordering the pipelines in a workflow pipeline, make sure that each pipeline can receive the output of the pipeline that precedes it. For more information, see Best practices for configuring stages and pipelines.

To reorder pipelines in a workflow:

Procedure

  1. Click the Workflow Designer window.

  2. Select the workflow that you want.

  3. Click the Processing window.

  4. Click and drag the pipelines into the order that you want.

Removing pipelines from a workflow

You can remove a pipeline from a workflow at any time. If you do this while a task is running for that workflow, any documents retrieved after the pipeline was removed will not be processed by that pipeline.

When you remove a pipeline, make sure that the pipeline after the one you're deleting can accept the output of the pipeline before the one you're deleting. If it cannot, you may need to reconfigure your pipelines. For more information, see Best practices for configuring stages and pipelines.
