LangGraph Interrupt and Resume Workflow - Part 4/22

Description

Learn how to implement interrupt and resume workflows in LangGraph using the interrupt() function and Command routing. This tutorial covers human-in-the-loop patterns, state persistence via checkpointers, and JSON-serializable payload handling for dynamic execution control. #LangGraph #Python #WorkflowAutomation #AI #InterruptionHandling #StateManagement #Tutorial Zen Koan Explanation: The code uses `interrupt()` to pause execution and request external input, holding the graph's state until a response is provided—like a clenched fist waiting for the world to whisper the answer. This mirrors the koan's theme of suspended anticipation, where the system patiently awaits the missing piece (human approval) to proceed, embodying both control and surrender in the flow of execution.
