Hi Biplob,
Flink is shipped with own serializers. POJOs and other datatypes are
analyzed automatically. Kryo is only the fallback option, if your class
does not meet the POJO criteria (see [1]). Usually, all
serialization/deserialization to e.g. RocksDB happens internally and the
user doesn't have to think about it.
Regards,
Timo

Hi,
I had a simple query as to how POJO's are stored in a state back end like
RocksDB? Is it deserialized internally(with a default serde or we have to
specify something)? and if yes, is Kryo the default serde?
Thanks,
Biplob
