Qian Li of DBOS, a durable execution platform
born from research by the creators of Postgres and Spark, speaks
with host Kanchan Shringi about building durable, observable, and
scalable software systems, and why that matters for modern
applications. They discuss database-backed program state,
workflow orchestration, real-world AI use cases, and comparisons
with other workflow technologies.

Li explains how DBOS persists not just application data but also
program execution state in Postgres to enable automatic recovery
and exactly-once execution. She outlines how DBOS uses workflow
and step annotations to build deterministic, fault-tolerant flows
for everything from e-commerce checkouts to LLM-powered agents.
Observability features, including SQL-accessible state tables and
a time-travel debugger, allow developers and business users to
understand and troubleshoot system behavior. Finally, she
compares DBOS with tools like Temporal and AWS Step Functions.
