Implementation Details

Checkpoint Backends

1. MemorySaver: In-memory checkpointing for development
2. SqliteSaver: SQLite-based persistence
3. PostgresSaver: PostgreSQL backend for production
4. RedisSaver: Redis-based high-performance checkpointing

Configuration Options

• Checkpoint frequency settings
• State serialization format
• Compression options
• TTL and retention policies
• Thread-safe access configuration

Best Practices

• Use appropriate backend for scale
• Implement proper serialization for custom state
• Design for checkpoint size optimization
• Plan for migration between backends

Dependencies

• langgraph
• langgraph-checkpoint
• Backend-specific clients
