Going from using only JPA/Hibernate for everything, to use a combination of both jOOQ and JPA/Hibernate on a project, is probably the best decision I've made. Using each tool at what I believe they do best.

I use JPA/Hibernate for most writing and inserts. It helps a lot when you're dealing with aggregates with child and child entities. It would be a nightmare to track all changes myself and try do manually do what the ORM is doing for me. Deleted a child of a child of an aggregate? No problem, persist only that.

I've started to separate my JPA/Hibernate entities from my domain models as well, and it looks promising. There's some more mappins, but my domain won't be polluted with database concerns.

Then I use jOOQ for almost all reading of data, reading into custom read models that fit the view they are supposed to be shown in. No problem doing multiple joins or other stuff that would give you an immediate headache when trying to solve using JPA/Hibernate.
