Answer / anonymous

checkpoints are normally used for the graph recovery.
if we are loading a large volume of data and the graph gets failed, so instead of rerunning the whole graph we can execute the graph from the last executed checkpoint.
it saves time and loads the data from the point where it failed.
checkpoints saves the intermediate files during the graph execution.

Pdl with an example?
