The Astronomer Registry was initially developed in 2021 to address the challenges of navigating Airflow's extensive ecosystem of over 1,000 operators, making it easier for data engineers to discover and utilize these tools without having to delve into source code. The original architecture utilized Airflow DAGs, Airtable, and a UI in React & TypeScript, allowing for rapid iteration and data issue resolution, which enabled scaling to millions of page views. However, its independence from Astronomer's main infrastructure limited feature development and integration. Consequently, a new Registry was built using a similar stack but introduced a Postgres database with materialized views and a Golang API to enhance performance, significantly reducing page load times from about one second to a few hundred milliseconds. This redesign aims to maintain high-speed operations while facilitating future improvements and new features.
