What are the caching strategies in Hibernate ORM?

What are the caching strategies in Hibernate ORM?

Hibernate ORM offers two main caching strategies: first-level cache and second-level cache. The first-level cache is associated with the session and is enabled by default, while the second-level cache is optional and can be shared across sessions.

Can you explain the difference between first-level and second-level cache?

Sure! The first-level cache is session-scoped, meaning it only exists during the session's lifetime. The second-level cache, on the other hand, is session-independent and can be shared across multiple sessions, improving performance by reducing database access.

What are some common providers for the second-level cache?

Common providers for the second-level cache in Hibernate include Ehcache, Infinispan, and Hazelcast. Each has its own features and configurations.

How do I configure second-level caching in my Hibernate application?

To configure second-level caching, you need to enable it in your Hibernate configuration file and specify the cache provider. You also need to annotate your entity classes with caching annotations.
