LangGraph Interrupt and Resume Workflow - Part 7/22

Description

Learn how to implement interrupt and resume workflows in LangGraph for human-in-the-loop processing. This tutorial covers checkpointing, state persistence with thread_id, and the Command pattern for resuming paused executions. #LangGraph #Python #AI #Workflow #Interruption #Resume #Tutorial Zen Koan Explanation: The code demonstrates how a graph execution can be paused (interrupted) and later resumed with modified data, but the original state before the interruption is preserved in the thread's memory. This mirrors the koan's theme where the thread (like a mind in meditation) remembers the moment of pause but doesn't inherently retain the subsequent edits - those must be explicitly provided when resuming, just as the koan suggests the edit was "begged to receive" but not automatically remembered.
