LangGraph Interrupt and Resume Workflow - Part 18/22

Description

Learn how LangGraph's interrupt mechanism enables safe human-in-the-loop workflows by combining idempotent database operations with approval flows. This tutorial covers checkpointing, state management, and strategic interrupt placement for resilient workflows. #LangGraph #Python #Workflow #StateManagement #AI #Checkpointing #Idempotency Zen Koan Explanation: The code uses `interrupt()` to pause execution and request human approval, but the subsequent `Command` (e.g., `goto="approved_path"`) unconditionally directs the workflow based on the decision—even if the state wasn’t explicitly updated to reflect that choice. This mirrors the koan’s theme: the interrupt *asks* for approval, but the state blindly follows predefined paths without verifying whether the approval was truly granted or aligned with the system’s intent. The pattern highlights a disconnect between human input and automated state transitions. Source: https://docs.langchain.com/oss/python/langgraph/interrupts
