What are the best practices for using JPA?
Some best practices for using JPA include using the EntityManager wisely, managing transactions effectively, and optimizing queries.
Can you explain how to optimize queries in JPA?
To optimize queries in JPA, consider using pagination, fetching strategies, and avoiding N+1 select problems.
What is the N+1 select problem?
The N+1 select problem occurs when a query retrieves a list of entities, and then for each entity, another query is executed to fetch related data.
How can I avoid the N+1 select problem?
You can avoid the N+1 select problem by using JOIN FETCH in your queries or by configuring your fetching strategy appropriately.
