Caching is one of the most effective techniques for improving the performance of modern Spring applications. Especially in microservice architectures or high-traffic APIs, a well-configured cache can significantly reduce database load and greatly improve response times. By storing frequently accessed data in memory, applications can avoid repeated expensive operations such as database queries or external API calls. This article provides a compact yet comprehensive overview of Spring’s caching capabilities.
For example, without caching, each request follows this process:
