## Specs that have no corresponding workflow pattern on workflowpatterns.com[](#specs-that-have-no-corresponding-workflow-pattern-on-workflowpatterns-com "Link to this heading")

- Execute - spawns a subprocess and waits for the results
- Transform - executes commands that can be used for data transforms
- Celery - executes a Celery task (see <http://celeryproject.org/>)
