LangGraph Interrupt and Resume Workflow - Part 20/22

Description

Learn how LangGraph handles interrupt and resume workflows in nested computational graphs. This tutorial covers dynamic execution pausing, stateful checkpointing, and re-execution semantics when interrupts occur in subgraphs. #LangGraph #Python #WorkflowAutomation #AI #GraphComputing #StateManagement Zen Koan Explanation: When a subgraph is interrupted, its execution pauses but its state is preserved in the checkpoint. Upon resumption, the subgraph "wakes up" and continues from where it left off, as if it had never been interrupted—its state "answers calls it never took" because the intermediate steps were skipped, yet the final state reflects the completed computation. This mirrors the koan's theme of apparent inaction (dozing) masking underlying persistence (state preservation). Source: https://docs.langchain.com/oss/python/langgraph/interrupts
