Fix N+1 Select Issues with Hibernate’s EntityGraphs
If you've used Hibernate for a while, I'm sure you know the N+1 SELECT issue. It's the most common performance problem and describes how Hibernate executes dozens or even hundreds of queries to fetch related entities.
In this video, I will show you how you can easily fix those issues using an EntityGraph.
An EntityGraph tells Hibernate which relationships it shall fetch from the database. Hibernate will then fetch your entity together with the defined set of relationships in just 1 query.
