Store integrations | LangChain 简体中文

Stores enable long-term memory in LangGraph, allowing agents to persist and retrieve information across threads.

To implement your own store for a custom storage backend, extend the BaseStore interface. To deploy a custom store on Agent Server, see Add a custom store.
