When a runtime service upgrade occurs in Databricks, any running tasks or pipelines may be temporarily interrupted while the upgrade is being applied. In the case of a cancelled Delta Live Table pipeline, it will not be impacted by the upgrade since it is not running.
However, if the upgrade involves changes to the Delta Lake format or features that the pipeline relies on, it is possible that the pipeline may need to be modified or updated in order to be compatible with the new runtime service. It is important to review any release notes or announcements related to the upgrade to determine if any action is required on your part to ensure your pipeline continues to function properly.
