# Checkpointer 集成

> 与LangGraph持久化所需的检查点后端集成（使用LangChain Python）

检查点器支持 LangGraph 中的 [持久化](https://langchain-docs-zh.mintlify.site/langchain/oss/langgraph/persistence.md)，使智能体能跨交互保存和恢复状态。

要为自定义存储后端实现自己的检查点器，请参考 [构建自定义检查点器](https://langchain-docs-zh.mintlify.site/langchain/oss/langgraph/checkpointers.md#构建-custom-checkpointer)。

Integration components
Arrows show a typical retrieval flow. The highlighted component is the one this page covers.

### Typical retrieval flow

### Agent capabilities
