stepPreviews

Information about the type of impact a runbook step would have on a resource.

• Mutating: The runbook step would make changes to the targets through actions that create, modify, or delete resources.

• Non_Mutating: The runbook step would retrieve data about resources but not make changes to them. This category generally includes Describe*, List*, Get*, and similar read-only API actions.

• Undetermined: An undetermined step invokes executions performed by another orchestration service like Lambda, Step Functions, or Amazon Web Services Systems Manager Run Command. An undetermined step might also call a third-party API. Systems Manager Automation doesn't know the outcome of the orchestration processes or third-party API executions, so the results of the steps are undetermined.
