🚀 LangGraph Crash Recovery Explained | Resume AI Workflow from Last Step using Redis

Ever wondered what happens when your AI chatbot workflow crashes in the middle of a long conversation?
In this video, we’ll show you step-by-step how to make your LangGraph workflows restart-proof using Redis.

What you’ll learn in this tutorial:

✅ How to implement crash recovery in LangGraph workflows
✅ Persisting workflow state after every step using Redis
✅ Resuming the workflow from the last successful step
✅ Difference between in-memory state and external persistence
✅ Building production-ready AI workflows that save cost and time

Demo Scenario:

Step 1 complete

Step 2 complete

Step 3 crash simulated

Redis stores the last safe state

Workflow resumes automatically from step 3

🎯 Why this is important:

Avoid duplicate LLM calls → save cost & time

Fault-tolerant AI workflows

Production-ready design

Great talking point for AI/ML interviews

💡 Tools used:

LangGraph – Node-based AI workflow automation

Redis – Persistent external state storage

Python – Workflow simulation & crash handling
