What type of data is typically stored in cache in Sitecore?

Typically, the type of data stored in cache in Sitecore consists of frequently accessed data. Caching is a performance optimization strategy used to store data that is often requested, thus reducing the time it takes to retrieve that data in subsequent requests. By keeping this frequently accessed data readily available in memory, Sitecore can enhance the speed of content delivery and improve overall application performance.

Caching is especially important for data that does not change very frequently but is required frequently during user interactions, such as rendered site components, item metadata, and configuration settings. This improves the user experience by reducing page load times and server load.

In contrast, archived user data is typically not frequently accessed, raw content files are usually managed through the file system and served directly via HTTP, and import/export configurations are administrative settings that don't need to be cached for quick access during runtime. These other data types do not benefit from being stored in cache in the same way that frequently accessed data does.
