HySDS Components: Factotum Topics

Helper Worker (factotum)

As stated previously, the helper subsystem (factotum) is a specialization of the compute service subsystem (verdi) that encapsulates the various 3rd party software and HySDS components related to the execution of system-based HySDS jobs and lightweight Celery tasks.

The helper subsystem plays a central role in the execution of jobs and tasks related to trigger rule evaluation. The diagram below depicts user_rules_datasets and user_rules_jobs celery workers running in the helper subsystem that perform the evaluation of trigger rules. Whenever trigger rule evaluation results in a match, the user_rules_dataset/user_rules_jobs worker submits a task for the user_rules_trigger celery workers also running in the helper subsystem to submit a job request to the orchestrator.
