Hi Alexey, I don't think the new reactive mode makes any changes to the checkpoint/savepoint mechanism, at least not at the moment.
However, you might want to take a look at the unaligned checkpoint [1]. The unaligned checkpoint is designed to be tolerant with back pressure. AFAIK, this can work with both the default and the new reactive modes.
