Armin Ronacher discusses creating a lightweight SQL library called Absurd for building durable workflows using only Postgres. It enables reliable execution of tasks that can survive failures and restarts by storing state information in the database. The approach avoids the complexity of third-party services, allowing for self-hosted solutions.

Durable Execution (DE) engines allow for the persistence of multi-step workflows, enabling them to resume from the last successful step after interruptions. This article explores the development of a simple DE engine called Persistasaurus in Java, which utilizes SQLite for logging execution state and highlights key implementation choices.
