Runspace Workflows

Back to PSFramework

Synopsis

Runspace Workflows allow easily architecting a set of steps that will be execute in parallel:

• For Each step of a workflow, define how many times it should be executed in parallel
• The results of one step become the input for the next step
• No need to deal with the details - just provide the business logic for each step

Description

The fundamental system of Runspace Workflow consists of three main components: The Workflow Object, the Worker and the Queue:

• Workflow Object: Represents the entire workflow and hosts all the interna, including the Workers and the Queues.
• Worker: An individual step in the workflow, the worker contains the business logic of that step, the configuration and the runspaces actually executing it.
• Queue: A workflow can have as many queues as desired. They ensure data gets exchanged between steps, usually the output of one step becoming the input of the next step.

Core Concepts

• The Workflow Object
• The Worker
• The Queue

Examples

While the details on the components may provide value, this system benefits most from some examples:

• A simple workflow
• Begin & End
• Including Variables, Functions and Modules
• Different variable value per runspace
• Automatically ending Workflows
• When the first step generates the input
• Branching Flows - One step feeding multiple others
• Data outside of the Queues
• Rate limiting - throttling and workflows
