Persist Agent State Across Restarts with LangGraph Checkpointing

Problem

Checkpointing is a persistence layer that maintains agent workflow state between executions.

Without checkpointing, agents lose all state when systems restart, requiring users to start over with new conversations.

Solution

With LangGraph’s checkpointing, you can persist agent state to databases, enabling:

• Conversation continuity through restarts
• Same conversation accessible from any application instance
• Flexible persistence with PostgreSQL, SQLite, or MongoDB backends
