Lightweight Durable Execution: The DBOS Transact Open-Source Library

Traditional durable execution relies on external orchestrators like AWS Step Functions, adding complexity to development and deployment. DBOS Transact is a lightweight open-source library that integrates durable execution into the program itself, eliminating the need for external orchestrators. It achieves durable execution by persisting the program's execution state in a Postgres database, allowing automatic recovery to the point of interruption even if the program crashes or restarts. DBOS Transact also provides additional features such as durable sleep, durable messaging, and durable queues, further simplifying the development of reliable, stateful programs.
