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
