SamWheating opened a new pull request #18159: URL: https://github.com/apache/airflow/pull/18159
**Re:** Discussion in https://github.com/apache/airflow/issues/17889 A few changes in this PR: - Update `Variable.set()` method to take a `description` argument. - Update `Variable.setdefault()` method to take a `description` argument. - Adding a `Variable.update()` method which will throw a `KeyError` if the Variable doesn't exist, and an `AttributeError` if it doesn't exist in the Database (since a non-metastore Variable can't be modified) - Improved logging around key collisions between different variable backends. - Updated documentation to warn users about key collisions between variable backends. If a user has a duplicated key in the metastore and an extra secrets backend, then updates to the Variable will update the value in the metastore, but reads will read the value in the additional backend. This is still the case, but I've improved the logging when this happens and updated the documentation to warn users about this behaviour. --- **^ Add meaningful description above** Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst#pull-request-guidelines)** for more information.
