Optimizing the performance by implementing caching

Caching is a common technique used to improve the performance of the application. In web API development, caching can store frequently accessed data in a temporary storage, such as memory or disk, to reduce the number of database queries and improve the responsiveness of the application. In this section, we will introduce the caching in ASP.NET Core web API development.

Caching is an effective tool when handling data that is not regularly updated but is costly to compute or obtain from the database. It is also useful when multiple clients access the same data frequently. As an example, consider an e-commerce application that displays a list of categories. The categories of the products are not often changed, yet they are frequently viewed by users. To improve the performance of the application, we can cache the categories. When a user requests the categories, the application can return the cached data directly without querying the...
