Apache Superset Feature Flags using superset_config.py and Custom Configuration (Without Docker)

In this comprehensive tutorial, learn how to activate and manage Apache Superset Feature Flags and custom configurations when you've installed Superset without Docker. Modifying the core config.py file is risky. Instead, we'll show you the best practice method: creating a persistent superset_config.py file in your virtual environment (venv) to safely override settings. You'll learn to: 1. Set up the custom configuration file. 2. Export the necessary PYTHONPATH to ensure Superset loads your custom settings. 3. Verify changes, such as modifying the app name to "SUPERSET CUSTOM" or enabling Thumbnails/Import-Export features. This guide is perfect for developers and data engineers looking for stable, non-Docker Superset customization.
