Introduction
Caching is a technique that helps in improving the performance of applications by reducing the number of requests that are made to an external system. We have already explored the basics of this concept as well as implemented in-memory caches. In this lesson, we will be discussing strategies for how and when to cache, specifically write-through, write-back, and write-around.
Write-through caching
Write-through caching is a caching strategy in which every write operation is written both to the cache and the ...
