Durable Execution in Data Pipelines

Summary
In this episode of the Data Engineering Podcast Jeremy Edberg, CEO of DBOS, about durable execution and its impact on designing and implementing business logic for data systems. Jeremy explains how DBOS's serverless platform and orchestrator provide local resilience and reduce operational overhead, ensuring exactly-once execution in distributed systems through the use of the Transact library. He discusses the importance of version management in long-running workflows and how DBOS simplifies system design by reducing infrastructure needs like queues and CI pipelines, making it beneficial for data pipelines, AI workloads, and agentic AI.

• Hello and welcome to the Data Engineering Podcast, the show about modern data management
• Data migrations are brutal. They drag on for months—sometimes years—burning through resources and crushing team morale. Datafold's AI-powered Migration Agent changes all that. Their unique combination of AI code translation and automated data validation has helped companies complete migrations up to 10 times faster than manual approaches. And they're so confident in their solution, they'll actually guarantee your timeline in writing. Ready to turn your year-long migration into weeks?

• Your host is Tobias Macey and today I'm interviewing Jeremy Edberg about durable execution and how it influences the design and implementation of business logic

Interview

• Introduction
• How did you get involved in the area of data management?
• Can you describe what DBOS is and the story behind it?
• What is durable execution?
  • What are some of the notable ways that inclusion of durable execution in an application architecture changes the ways that the rest of the application is implemented? (e.g. error handling, logic flow, etc.)
• Many data pipelines involve complex, multi-step workflows. How does DBOS simplify the creation and management of resilient data pipelines? 
• How does durable execution impact the operational complexity of data management systems?
• One of the complexities in durable execution is managing code/data changes to workflows while existing executions are still processing. What are some of the useful patterns for addressing that challenge and how does DBOS help?
• Can you describe how DBOS is architected?
  • How have the design and goals of the system changed since you first started working on it?
• What are the characteristics of Postgres that make it suitable for the persistence mechanism of DBOS?
• What are the guiding principles that you rely on to determine the boundaries between the open source and commercial elements of DBOS?
• What are the most interesting, innovative, or unexpected ways that you have seen DBOS used?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on DBOS?
• When is DBOS the wrong choice?
• What do you have planned for the future of DBOS?
