Supported Apache Airflow configurations
Note
This feature is in public preview. Workflow Orchestration Manager is powered by Apache Airflow.
In Workflow Orchestration Manager, Apache Airflow configurations can be integrated with the platform's runtime as key-value pairs. While the airflow.cfg isn't directly accessible in the UI, users can override these configurations via the UI's "Airflow Configuration overrides" section, retaining access to other airflow.cfg settings. Developers have the flexibility to override most Apache Airflow configurations within Workflow Orchestration Manager, except for those explicitly outlined in a provided table.
