Hi Alexey,
Flink supports rescaling from a normal checkpoint if you are not changing
your application too much. So if normal checkpointing works, you can just
use that for rescaling by using Retained Checkpoints and supply the path on
resume at the place where you supplied the savepoint path befor
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
Hello,
Is new reactive mode can operate under back pressure? Old manual rescaling via
taking savepoint didn't work with system under back pressure, since it was
practically impossible to take savepoint, so wondering is reactive mode
expected to be better in this regards ?
Thanks,
Alexey
