Cache Strategies
Explore key cache strategies used to improve application performance and scalability. Understand how cache-aside, write-through, write-back, and read-through approaches work to optimize data retrieval and consistency in software systems.
We'll cover the following...
Overview
Cache strategies are techniques or approaches used to design and implement caching in order to improve the performance and scalability of a system or application. Some important cache strategies include:
Cache-aside
Cache-aside is a cache strategy that involves checking the cache for a requested item before retrieving it from the original source. If the item isn’t found in the cache, it’s retrieved from the original source and stored in the cache for future use. This strategy allows the cache to be updated with the latest data from the original source while still providing the benefits of caching.
Example
An example of the cache-aside strategy is when a web application needs to retrieve data from a database. Instead of always going directly to the database, the application first checks if the data is available in the cache. If the data isn’t found in ...
