Hey, I wanted to know why we have the SerializableSerializer when we encounter an unregistered class and what advantage we get by using it over the FieldsSerializer from kryo. I did some very basic performance testing and the FieldsSerializer seems to perform better than SerializableSerializer. I could not get context on why the SerializableSerializer came to be from the git history. Would appreciate any insights. TIA.
Regards, Mahesh
