Building a Durable Execution Engine With SQLite

This technical article delves into implementing a Durable Execution (DE) engine with SQLite in Java. It explains how DE makes long-running, multi-step workflows (e.g., purchase orders, agentic AI flows) resilient to failures by persisting state. The author aims to create a basic, sub-1000-line prototype to understand the core concepts of checkpointing, state management, and resumption, contrasting modern code-based workflows with older automation platforms.
