Persistence in LangGraph — Deep, Practical Guide
Persistence in LangGraph means storing and restoring graph state so an agent/workflow can:

The article explores the importance of persistence in LangGraph, focusing on how it enables workflows to retain their state across crashes, facilitate long-running tasks, and support multi-turn conversations without losing context. It details various aspects such as state checkpointing, persistence architecture, built-in checkpointing, and the architectural patterns that LangGraph employs to maintain workflow continuity. The article emphasizes best practices for implementing persistence, including schema versioning and the use of custom persistence backends, ultimately demonstrating how these strategies empower agentic systems for more reliable and auditable processes.
