+                        - Switching to a different POJO style that doesn't require mandatory canonical constructors
+                        - Use replacing embeddables to reduce the column number: https://www.jooq.org/doc/latest/manual/code-generation/codegen-embeddable-types/codegen-embeddable-types-replacing-fields/
