Phases are used to divide the graph into small pieces and less the usage of resources like CPU and memory

Checkpoints are the commit points where we can revert back the saved data,

Phasing: Phasing in ab-initio means dividing the complex graphs into pieces. In order to improve the performance by reducing the resource utilization in different phases with in the same graph.

Check Point: Checkpoint in abinitio means the end point of each phase. If we checkpoint the each phase in ab initio graph in case of failure of graph during its execution we can recover the graph up to last committed check point.

For efficient graph management to channelize the priority of the outputs we use phases

coming to check points,we use them to consume time that takes while running graphs..

By placing checkpoints graph resumes to run from its earliest checkpoint.
