>
> In JobGenerator, the code reads like that some batches might not get marked
> as fully processed. In the following flowchart, the batch should get marked
> fully processed before endpoint C however it is not. Currently, this does not
> actually cause an issue, as the condition {code}(time - zeroTime) is multiple
> of checkpoint duration?{code} always evaluates to true as the checkpoint
> duration is always set to be equal to the batch duration.
