Orchestration Pipeline Overview
An orchestration pipeline is a Data Collector pipeline that uses one or more orchestration stages to schedule and perform tasks, such as starting a sequence of Data Collector pipelines and Control Hub jobs. Use orchestration pipelines to perform tasks in an orchestrated workflow across the StreamSets platform.
For example, you can create an orchestration pipeline that starts several Data Collector, Data Collector Edge, and Transformer pipelines at 1 am every day. If you use Control Hub, you can similarly create an orchestration pipeline that starts Transformer jobs, then triggers Data Collector jobs only if the Transformer jobs successfully complete.
A typical orchestration pipeline generates a single record. As each orchestration stage completes its task, it adds information about the task that it performed to the orchestration record. For example, the Start Pipelines origin lists the pipeline ID and status of each pipeline that it starts. When the orchestration pipeline completes, the resulting orchestration record provides details about all of the tasks performed by the pipeline.
You can use other Data Collector stages in an orchestration pipeline to create the workflow that you need. For example, you might add a Stream Selector processor that routes the record to different branches based on whether a Control Hub job succeeded or failed. Or, you might use an Email executor to send an email after the workflow is complete.
An orchestration pipeline can be configured in any logical way. Review the documentation for the orchestration stages to see how you might orchestrate your workflows.
