Checkpoint Resumption SLA
sub-12ms replay
Verified: Zero State LossWhat you will learn
- StateGraph provides cyclical graph execution with typed reducers and state persistence.
- SqliteSaver and PostgresSaver enable instant pause, human-in-the-loop review, and resumption from exact checkpoint IDs.
- Hierarchical supervisor graphs coordinate specialized domain agents with bounded context windows.
Series: Agentic Engineering Patterns (Part 2 of 4)
1. The Checkpointer Pattern for Durable Agent Execution
Building robust multi-agent systems requires surviving container crashes, network timeouts, and human approval delays. LangGraph solves this by persisting every superstep state to an external checkpointer database.
Any graph execution can be suspended, inspected in developer tooling, approved by a human operator, and resumed seamlessly.
