=== Type system / custom types

==== Influencing SqlTypeDescriptor to use

Discuss `JdbcTypeCode`, `JdbcType`, `JdbcTypeRegistration`

==== Influencing JavaTypeDescriptor to use

Discuss `@JavaType`, `@JavaTypeRegistration`


==== Component Mapping

Multiple component mappings for the same java class with different property mappings is not supported anymore. Every property mapping combination should have its own java class"


=== SQM

* Functions
* Multi-table bulk manipulation HQL/Criteria query handling
