Phases divide the graph in to parts and executes one after the other to reduce the complexity and encounter deadlocks.
check points are like intermediate nodes which saves the data in to the disk permanently.We have to manual delete the data if we have checkpoints.If we have a successful checkpoint we can always roll back and rerun the graph from that point in case of a failure.
