----------------------------------------
At least with regard to kafka offsets, it might be good to keep this the same format as in
SPARK-17812
> Stable format for offset log

> Currently we use java serialization for the WAL that stores the offsets contained in
each batch. This has two main issues:
> - It can break across spark releases (though this is not the only thing preventing us
from upgrading a running query)
> - It is unnecessarily opaque to the user.
> I'd propose we require offsets to provide a user readable serialization and use that
instead. JSON is probably a good option.
