langgraph-persistence

You can persist LangGraph state by configuring a checkpointer like InMemorySaver, SqliteSaver, or PostgresSaver, and assigning a thread_id to isolate conversations and maintain durable execution history.

You need to configure subgraph persistence modes in LangGraph when managing interrupts, resuming state history, forking, or parallelizing subgraph executions during time travel operations.

Yes, LangGraph persistence supports PostgresSaver for production environments, while InMemorySaver and SqliteSaver are available for development readiness.

You can enable cross-thread memory using LangGraph checkpointer scoping by integrating a pluggable Store API to manage long-term memory across multiple threads and isolated conversations.

The best way to manage thread_id scoping for LangGraph state history is to use a pluggable checkpointer API that tags conversations and isolates thread state for durable execution.
