Data Caching
Data caching is a technique for storing frequently accessed data in a temporary, high-speed storage location to reduce latency and improve application performance. It involves keeping copies of data from a primary source (like a database or API) in a faster-access cache, allowing subsequent requests to be served more quickly. This concept is fundamental in computing to optimize resource usage and enhance user experience.
Developers should use data caching when building applications that require fast response times, such as web services, mobile apps, or real-time systems, to reduce load on backend systems and handle high traffic efficiently. It's particularly useful for read-heavy workloads, static content, or data that changes infrequently, as it minimizes database queries and network calls. Learning caching is essential for scalability and performance optimization in modern software development.
