------------------------------------
Fix Version/s: 3.0.0-alpha4
> Class inheritance and effectively final fields
> ----------------------------------------------
>
> Key: IGNITE-15945
> URL: https://issues.apache.org/jira/browse/IGNITE-15945
> Project: Ignite
> Issue Type: Task
> Reporter: Semyon Danilov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-alpha4
>
>
> Support inheritance of user objects and polymorphic fields.
> During the class instance (de)serialization, the (de)serializer traverses the
> fields from the descriptor and writes:
> * Field's value class descriptor ID and field data if the declared field's
> class is non-final. This allows supporting polymorphic fields.
> * Field data without field value class descriptor if declared field's class
> is final. In this case, the actual field's value object is guaranteed to be
> equal to the declared field class.
