Answer / freak.abinitio

check point is the recovery points created.........whenever the graph fails in middle. we can get the data from the failed checkpoint and try to execute it from that point after the correction.


phase:when graph created with phases part of memory will allocated to each phase one by one..[memory managment] phase will always be runing one after the other.

Answer / md

Using checkpoint if graph fails you can process rest of the
process from the point where it abended.
using Phase you need to run whole graph again. even ur
intermediate files will also get deleted.
