How to fetch multiple JPA collections with Blaze Persistence MULTISET
Introduction In this article, we are going to see how we can fetch multiple JPA entity collections without generating an implicit Cartesian Product with the MULTISET strategy offered by the Blaze Persistence open-source project. The MULTISET fetch strategy is inspired by the MULTISET operator offered by jOOQ. If you are not familiar with the MULTISET operator, then check out this article first, in which I explain why this jOOQ feature is truly revolutionary.
How to fetch multiple to-many relationships with jOOQ MULTISET
Introduction In this article, we are going to see how we can fetch multiple to-many relationships with jOOQ MULTISET so that we avoid bumping into an unintentional Cartesian Product. The approach taken by jOOQ is truly revolutionary since it offers a solution that allows you to fetch multiple to-many relationships using a single type-safe query.
