What is Caching in System Design?
Caching is a technique used to store copies of frequently accessed data in a temporary storage location, known as a cache. By keeping this data closer to the requesting entity (such as a CPU, application, or user), caching reduces the time and resources required to fetch the data from its primary storage location. Caching can significantly improve system performance by reducing latency, decreasing bandwidth usage, and lowering the load on backend systems.
Cold and Warm Cache in System Design
In the world of system design, caching plays a pivotal role in enhancing performance, reducing latency, and optimizing resource utilization. Understanding the importance of caching, particularly the concepts of cold and warm caches, is essential for designing efficient systems. This article delves into the fundamentals of caching, explores the differences between cold and warm caches, discusses strategies for managing these caches, and examines real-world applications, challenges, and tools associated with each.
