Start a Pipeline Automatically Using Periodic Checks

Pipelines start automatically when repository changes are detected, and one method of change detection is periodic checks. Periodic checks can be enabled or disabled using the PollForSourceChanges flag. For pipelines created or updated using the CLI, this parameter defaults to true, but this is not the recommended configuration. Instead, update your pipeline to use the recommended change-detection method and then set this parameter to false.

For more information about creating a pipeline with the recommended configuration, see Create a Pipeline (Console) and Create a Pipeline (CLI). For more information about updating an action or pipeline with the recommended configuration, see Edit a Pipeline (Console) and Edit a Pipeline (CLI).
