Java ORM test

Initial assumptions

• JPA is f***ing slow, due too many layers of abstraction
• NO xml and other shit-styled non-code-like sources must be needed
• no additional tools to work (only boxed with technology set or none is applicable)

Initila list of techs

• Apache Cayenne
• Ebean
• MyBatis
• jOOQ
• speedment
• Hibernate (as JPA representative - zero mark)

Initial criteria

Must:

• encrypted columns
• no raw SQL for simple CRUD operations
• support for PostgreSQL

Good to see if:

• support for MariaDB
• support extended PostgreSQL features (including json and array)
• "N+1" problem automatic solutions (as much as possible)
• ability to generate raw SQL (to be executed elsewhere)
