Question: Phase verses Checkpoint
Answer: Difference between a phase and checkpoint as far as i know it something related with how temporary files containing the data landed to disk is handled.
that is phases are used to break up a graph so that it does not use up all the memory , it reduce the no of component running in parallel hence improves the performances (used for performance fine tuning, by managing the resource in perfect manner)
Check points are used for the purpose of recovery. |
