During graph execution, the Checkpointer serializes and saves the current State as a checkpoint every time it passes through a node, recording version and parent-child relationships to form a traceable state tree; this is the underlying reason enabling time travel, breakpoint recovery, and Human-in-the-Loop pauses.

UnverifiedGradient Checkpointing is a technique that trades time for memory by not saving all intermediate activation values during training, instead recomputing them on demand during backpropagation to reduce GPU memory usage76% similarVerifiedLangGraph's Interrupt mechanism allows breakpoints to be injected at any node during graph execution, serializing and persisting the current state, and resuming execution with the approval result after human review.75% similarVerifiedLangGraph combined with the Checkpointer mechanism can pause at any node, resume after auditing, and supports checkpoint-based resumption.74% similarUnverified该节点每接受一个片段就生成一个检查点，程序崩溃或中途暂停时可从断点继续73% similar
