I noticed that you use the @Transactional annotation on class definition. This will create a write transaction for every public method of the annotated class, including read only methods. You should consider using readOnly=true for read methods.

Additionally, I would consider using two data sources, one for write queries and a read only ds for the Q part of CQRS.

Thanks for suggestions. I will add @Transactional(readOnly = true) annotation. I will mention in the README the possibility of using two data sources.

alright thanks. this java stuff is pretty hard for me to follow. it looks like java is doing the aggregating, but maybe this is some kind of ORM
