Time Travel

• Lets see how langgrpah supports debugging by viewing, replaying and even forking past states

• To browse history we can use graph.get_state on the graphs side to fetch the information and we can also browse the state history of our agent using get_state_history

• If you want to run the grap from a particular checkpoint with out changing any state, this is considered replay and to do replay graph.stream(input=None, config=to_replay.config, stream_mode="values")
• If we want to run from a step but with a different input, this is called as forking

• Refer Here for the jupyter notebook to perform time travel by using langgraph
