What are some examples of the cache-aside strategy?

The cache-aside strategy involves loading data into the cache only when it's needed. For example, when an application requests data, it first checks the cache. If the data is not there, it retrieves it from the database and then stores it in the cache for future requests.

Can you give me a specific use case?

Sure! A common use case is an e-commerce website. When a user views a product, the application checks the cache for product details. If not found, it fetches the details from the database, caches them, and then displays them to the user.

What are the benefits of using this strategy?

The benefits include reduced database load, faster data retrieval for users, and improved application performance.

Are there any drawbacks?

Yes, potential drawbacks include cache staleness, increased complexity in cache management, and the need for a strategy to handle cache misses.
