How can I optimize my Spring Boot queries?
You can optimize your Spring Boot queries by using pagination, caching, and writing efficient JPQL or SQL queries.
What is pagination and how do I implement it?
Pagination allows you to retrieve a subset of results instead of all at once. You can implement it using the Pageable
interface in Spring Data.
Can you give me an example of a JPQL query?
Sure! A simple JPQL query could be: SELECT u FROM User u WHERE u.age > :age
where :age
is a parameter.
How does caching improve performance?
Caching stores frequently accessed data in memory, reducing the need to hit the database for every request, thus improving performance.
