langgraph-persistence

Persist LangGraph state by compiling your graph with a checkpointer and invoking it with a thread_id to scope memory across multi-turn conversations.

The best way to share memory across different LangGraph threads is to use a Store, which enables cross-thread data sharing and shared user preferences across conversations.

Yes, LangGraph persistence works with SQLite and Postgres backends. It supports InMemorySaver, SQLiteSaver, and PostgresSaver checkpointers for development through production environments.

You can resume or fork past states in LangGraph subgraphs by using the time travel-like navigation of state history provided by the persistence layer's checkpointing mechanism.

You need to configure a thread_id for LangGraph state management whenever you require thread-scoped conversation history or want to isolate persistence data across multiple concurrent subgraphs.

Yes, you can use LangGraph checkpointers to save long-running workflow states. They enable durable execution by checkpointing graph state to your chosen backend.
