- Workflows and application data can be co-located in the same Postgres database, enabling updates in the same transaction to simplify fault tolerance.
- Co-location allows transactional steps to achieve exactly-once execution semantics by combining database updates and checkpoints in a single transaction, eliminating the need for external idempotency logic.
- A transactional workflow outbox pattern can be implemented within the same database using user-defined functions to ensure atomic updates and notifications, reducing operational complexity compared to separate systems.
- DBOS provides tools for building scalable, reliable systems with Postgres-backed durable execution.
