Till Rohrmann updated FLINK-22256:
----------------------------------
Description:
As a user, it is retrospectively difficult to determine what kind of checkpoint
(i.e. incremental, unaligned, ...) was performed when looking only at the
persisted checkpoint metadata.
The only way would be to look into the execution configuration of the job which
might not be available anymore and can be scattered across the application code
and cluster configuration.
It would be highly beneficial if such information would be part of the
persisted metadata to not track these external pointers.
It would also be great to persist the metadata information in a standardized
format so that external projects don't need to use Flink's metadata serializers
to access it.
