Just Use Postgres for Durable Workflows

5 hours ago

Durable workflows checkpoint program progress to a database for reliable recovery from failures.
External orchestration uses a central orchestrator to manage workflow steps, but it adds complexity.
Leveraging Postgres as the orchestrator simplifies workflows by enabling direct database interaction for checkpointing and coordination.
Scalability and availability in a database-backed system rely on the underlying database's capabilities and established solutions.
Observability is built-in with Postgres, as SQL queries enable real-time monitoring and analysis of workflows.
Reliability and security are enhanced by eliminating external single points of failure and leveraging database integrity.
The approach integrates with existing infrastructure, reducing the need for additional hardened components.
