LangGraph Persistence: Checkpoints That Unlock Resume and HITL
LangGraph persistence explained: how checkpoints store state per thread so interrupts, human in the loop approval, retries and time-travel debugging work.
7 min readLangGraph for production agents: checkpoints, HITL, and multi-agent graphs
Why chains stall on cycles and resume, and how LangGraph nodes, edges and checkpoint savers make production agents operable, with human in the loop review.
7 min readLangGraph Persistence Part 2: PostgresSavers, HITL, and Production Backends
Move LangGraph from InMemorySaver to PostgresSaver with PostgreSQL pools and async savers, compare SQLite and Redis, and run interrupt and resume in prod.
10 min readLangGraph Catalog and Invoice Agents with LangSmith Visibility
Catalog and invoice agents in LangGraph: supervisor routing, human in the loop interrupts, long term memory and LangSmith evaluation loops that keep it honest.
21 min readLangGraph research agent with LlamaIndex retrieval and HITL coding
Format-aware chunking, structured intent routing, parallel specialist retrievers, and interrupt-gated CLI coding turn papers into executable experiments safely.
4 min readBreak multi-intent human messages into LangGraph subtask plans
Lead supervisors should parse packed human requests into typed subtasks so request and search teams stop inheriting the wrong topic from a shared megaphone message.
5 min readHardening Agentic Graphs: State Contracts, Isolation, and HITL Gates
Production reliability for LangGraph: flat TypedDict state contracts, single-purpose nodes, retry and error edges, human in the loop gates and observability.
