Summary
In this episode of the Data Engineering Podcast Pete DeJoy, co-founder and product lead at Astronomer, talks about building and managing Airflow pipelines on Astronomer and the upcoming improvements in Airflow 3. Pete shares his journey into data engineering, discusses Astronomer's contributions to the Airflow project, and highlights the critical role of Airflow in powering operational data products. He covers the evolution of Airflow, its position in the data ecosystem, and the challenges faced by data engineers, including infrastructure management and observability. The conversation also touches on the upcoming Airflow 3 release, which introduces data awareness, architectural improvements, and multi-language support, and Astronomer's observability suite, Astro Observe, which provides insights and proactive recommendations for Airflow users.

• Your host is Tobias Macey and today I'm interviewing Pete DeJoy about building and managing Airflow pipelines on Astronomer and the upcoming improvements in Airflow 3

Interview

• Introduction
• Can you describe what Astronomer is and the story behind it?
• How would you characterize the relationship between Airflow and Astronomer?
• Astronomer just released your State of Airflow 2025 Report yesterday and it is the largest data engineering survey ever with over 5,000 respondents. Can you talk a bit about top level findings in the report?
• What about the overall growth of the Airflow project over time?
• How have the focus and features of Astronomer changed since it was last featured on the show in 2017?
• Astro Observe GA’d in early February, what does the addition of pipeline observability mean for your customers? 
• What are other capabilities similar in scope to observability that Astronomer is looking at adding to the platform?
• Why is Airflow so critical in providing an elevated Observability–or cataloging, or something simlar - experience in a DataOps platform? 
  • What are the notable evolutions in the Airflow project and ecosystem in that time?
• What are the core improvements that are planned for Airflow 3.0?
• What are the most interesting, innovative, or unexpected ways that you have seen Astro used?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on Airflow and Astro?
• What do you have planned for the future of Astro/Astronomer/Airflow?
