Plugins

The plugins folder (plugins/) is where Airflow looks for custom extensions — drop a Python file defining a custom Operator, Hook, Sensor, or UI view there, and Airflow registers it automatically on startup.

Common uses:

• Custom Operators — wrap a repeated piece of task logic (e.g. a company-specific API call) into a reusable, DAG-ready building block
• Custom Hooks — reusable connection logic to an external system
• UI extensions — add custom menu items or views to the Airflow UI

Keeps shared logic out of individual DAG files, so multiple DAGs can reuse the same tested building blocks.
