Very good question! As the documentation mentions, the old way was to
use `setNumberOfExecutionRerties` but it has been replaced by
`setRestartStrategy`.
If you don't configure anything, then your job will _not_ be
restarted. However, if you have enabled checkpointing, then your
application will be restarted infinitely. You can change that behavior
with setRestartStrategy or setNumberOfExecutionRerties (wouldn't use
it because it is deprecated).
I'll update the documentation to provide more clarity.
Thanks,
Max
