Gyula Fora commented on FLINK-4948:
-----------------------------------
I think in general this would be very nice but what about tools that might want
to alter the checkpoints intentionally for some reasons. Maybe
cleaning/transforming the state. So I think we should aim for some flexible
checking logic here.
> Consider using checksums or similar to detect bad checkpoints

> We should consider proactively checking to verify that checkpoints are valid
> when reading (and maybe writing). This should help prevent any possible
> state corruption issues that might otherwise go undetected.
