langgraph persistence
What it does
- Checkpointer: Saves/loads graph state at every super-step
- Thread ID: Identifies separate checkpoint sequences (conversations)
- Store: Cross-thread memory for user preferences, facts
- Short-term (checkpointer): Thread-scoped conversation history
- Long-term (store): Cross-thread user preferences, facts
- checkpointer=False — Subgraph doesn't need interrupts or persistence. Simplest option, no checkpoint overhead.
- checkpointer=True — Subgraph needs to remember state across invocations (multi-turn conversations). Each call picks up where the last left off.
Requirements & configuration
- When compiling a subgraph, the checkpointer parameter controls persistence behavior. This is critical for subgraphs that use interrupts, need multi-turn memory, or run in parallel.
- checkpointer=False — Subgraph doesn't need interrupts or persistence. Simplest option, no checkpoint overhead.
- checkpointer=True — Subgraph needs to remember state across invocations (multi-turn conversations). Each call picks up where the last left off.
- Need interrupts but not cross-invocation persistence (default)
- Need cross-invocation persistence (stateful)

langgraph-persistence FAQ
What does the langgraph-persistence skill do?
INVOKE THIS SKILL when your LangGraph needs to persist state, remember conversations, travel through history, or configure subgraph checkpointer scoping. Covers checkpointers, thread_id, time travel, Store, and subgraph persistence modes. Checkpointer: Saves/loads graph state at every super-step Thread ID: Identifies separate checkpoint sequences (conversations)
