After specifying Check points if a graph fails at one
particular point,then by making necessary modifications at
that point we can make the graph run, instead of running the
graph from the beginning.
If there are several branches in a graph we can specify
Phases for each branch, so that after the completion of
successive branch only the next phase execution starts.So
that the processing will be reduced and the performance will
be increased.
You cant run from 51000th record if all the 1 lakh records
are in a single file.The graph should run from 1st record.
It can be achieved if there are different comtonents holding
1 lakh records.
