László Bodor updated HIVE-22944:
--------------------------------
Description:
Maybe we should consider upgrading to kryo5 (plan ser/deser). Not sure about
performance benefits, but looking at the code, e.g. FieldSerializer in Kryo5
seems to let us extend it easier (less private fields), which could be a
benefit if we want to change its behavior, e.g. defining different logic for
different fields of an object.
Kryo 4 FieldSerializer:

Kryo 5 FieldSerialier:
