langgraph-persistence

What problem does it solve?

This Skill addresses the need for durable execution in LangGraph applications by providing mechanisms to save, load, and manage the state of graph executions, enabling features like conversation history and time travel.

Core Features & Use Cases

• State Persistence: Save and load graph states using various backends (in-memory, SQLite, PostgreSQL).
• Conversation History: Maintain and access past states for a given thread ID.
• Time Travel: Replay, fork, or update states from historical checkpoints.
• Long-Term Memory: Utilize a Store for cross-thread memory, storing user preferences or facts.
• Subgraph Scoping: Control persistence behavior for subgraphs, managing interrupts and multi-turn memory.

Quick Start

Invoke the langgraph-persistence skill to set up a basic graph with in-memory checkpointing and thread-based state persistence.
