Transactional Serverless with DBOS
summary
Claims a concrete stack and behavior: an open-source DBOS transact TypeScript Node.js framework plus a managed DBOS cloud platform that uses Firecracker for execution, records workflow metadata in the database with snapshot isolation, and resumes crashed workflows exactly where they left off. Demonstrates a live widget-store checkout, shows OpenTelemetry spans, documents time travel debugging of database state, explains that DB transactions are exactly-once while external API calls are at-least-once and require idempotency keys.
