pg_durable

pg_durable is an open-source PostgreSQL extension from Microsoft that brings durable execution directly into the database. It allows developers to build reliable, stateful workflows that survive crashes and restarts by leveraging PostgreSQL's transactional guarantees. The extension provides a framework for orchestrating multi-step processes with automatic retries, checkpointing, and idempotency, eliminating the need for external workflow engines or additional infrastructure. By running inside the database, pg_durable reduces latency and operational complexity for applications that require strong consistency and fault tolerance. It is designed for use cases such as payment processing, order fulfillment, and any scenario where exactly-once execution is critical. The project is hosted on GitHub under the MIT license and is actively maintained by Microsoft. Based on community signals so far, pg_durable addresses the gap between simple database transactions and full-fledged durable execution frameworks like Temporal or Azure Durable Functions, offering a lightweight alternative for PostgreSQL users.

Microsoft open-sourced pg_durable on GitHub, generating discussion on Hacker News as a fresh approach to durable execution inside PostgreSQL.
