What are the caching strategies in Spring Boot JPA?

What are the caching strategies in Spring Boot JPA?

In Spring Boot JPA, caching strategies include first-level cache, second-level cache, and query cache. First-level cache is enabled by default and is session-scoped, while second-level cache is shared across sessions and can be configured with providers like Ehcache or Hazelcast.

Can you explain how to configure second-level caching?

To configure second-level caching, you need to add a caching provider dependency in your pom.xml or build.gradle, then enable it in your application.properties by setting spring.jpa.properties.hibernate.cache.use_second_level_cache=true and specifying the cache provider.

What are the benefits of using caching in JPA?

Caching in JPA improves performance by reducing database access, decreasing latency, and enhancing application scalability. It allows frequently accessed data to be stored in memory, leading to faster retrieval.

Are there any downsides to using caching?

Yes, potential downsides include increased memory usage, complexity in cache management, and the risk of stale data if the cache is not properly invalidated.
