Sean Lopp built a data pipeline and dashboard to compare resort conditions in Colorado, using Dagster to manage the process. He found Dagster's dataset-awareness and strong opinions on code structure made it ideal for his project. The tool allowed him to separate production, staging, and local development, making it easy to deploy and test his code. Dagster's architecture also provided better performance and scalability compared to other schedulers like Airflow. Lopp was impressed with Dagster's capabilities and is now helping teams evaluate the tool to see its benefits for themselves.
