JPA batch fetching is a technique used to optimize database access by loading multiple entities in a single query. This reduces the number of database calls.
What are the benefits of using batch fetching?
The main benefits include improved performance, reduced latency, and decreased load on the database by minimizing the number of queries.
Can you give an example of how to implement batch fetching in JPA?
Sure! You can use the @BatchSize annotation on your entity to specify the number of entities to fetch in a single batch.
Are there any downsides to using batch fetching?
Yes, if the batch size is too large, it can lead to memory issues. It's important to find a balance based on your application's needs.
