How can I optimize Hibernate criteria queries for better performance?

To optimize Hibernate criteria queries, consider using projections to fetch only necessary fields, and avoid fetching large collections unless needed.

What are projections in Hibernate?

Projections in Hibernate allow you to select specific fields from your entities instead of fetching entire objects, which can improve performance.

Are there any other techniques to improve performance?

Yes, you can also use pagination to limit the number of results returned, and ensure proper indexing in your database.

How does indexing affect query performance?

Indexing improves query performance by allowing the database to find and retrieve data more quickly, reducing the amount of data scanned.
