What is caching in Spring Boot and why is it important?

Caching in Spring Boot is a mechanism to store frequently accessed data in memory to improve application performance. It's important because it reduces the time taken to fetch data from the database, leading to faster response times and reduced load on the database.

How can I implement caching in my Spring Boot application?

You can implement caching in Spring Boot by using the @Cacheable annotation on methods that fetch data. Additionally, you need to enable caching in your configuration class using @EnableCaching.

What caching providers can I use with Spring Boot?

You can use various caching providers with Spring Boot, such as Ehcache, Hazelcast, Caffeine, and Redis. Each has its own advantages depending on your use case.

Can you explain the difference between @Cacheable and @CachePut?

Certainly! @Cacheable is used to cache the result of a method, while @CachePut updates the cache without interfering with the method execution. Use @CachePut when you want to ensure the cache is updated with the latest data.
