> Today, if there is an incorrect number of partitions on the job's checkpoint topic, the job will fail right away. The topic should have 1 partition.
> Unfortunately, there is no easy solution for this problem, since the number of partitions on the topic cannot be decreased (or topic cannot be deleted).
> We should add a config that will allow just to issue a warning in this case and keep going. We also need to make sure the checkpoints are written to partition 0 only.
