Overview¶

Objects are returned from Rules during a translation, and are rendered to produce an Apache Airflow Project

An OrbiterProject holds everything necessary to render an Airflow Project. It is generated by a TranslationRuleset.translate_fn.

Workflows are represented by a OrbiterDAG which is a Directed Acyclic Graph (of Tasks).

OrbiterOperators represent Airflow Tasks, which are units of work. An Operator is a pre-defined task with specific functionality.
