Develop the consolidation/unification of the numerous type systems implemented by Hibernate:
* its own org.hibernate.type.Type system
* JPA type system
* SQM type system
Will entail a some major set of refactoring to
the {{org.hibernate.type}} package. Much of this redesign is discussed at https://github.com/hibernate/hibernate-orm/wiki/6.0---Type-redesign
Also needs to ultimately swap ResultSet value extraction by name to extraction by position (perf) which is highly disruptive change (custom type impls). |
