Caching is the process of temporarily storing results to reduce recomputation needs by allowing systems to return data from cache, improving load and response.
Spring Boot simplifies caching via spring-boot-starter-cache, which supports various backends like ConcurrentHashMap, Ehcache, and Redis for efficient data management.
By annotating methods with @Cacheable, Spring Boot can bypass method execution if data is already cached, substantially enhancing application performance.
