Hi Padarn, By default the checkpoint would be disposed when the job finished or failed, they would be retained only when explicitly required [1].
From the implementation perspective I think users could be able to change topology when restored from external checkpoint, but I think Flink would not guarantee this functionality.

Or can it also work for checkpoints? (also why if not) Cheers, Padarn
