What is the cache-aside strategy in caching?

The cache-aside strategy is a caching pattern where the application code is responsible for loading data into the cache.

How does it differ from other caching strategies?

Unlike write-through or write-back strategies, cache-aside only loads data into the cache when it's requested.

What are the benefits of using cache-aside?

It improves performance by reducing database load and speeds up data retrieval for frequently accessed data.

Are there any downsides to this strategy?

Yes, it can lead to cache misses if the data isn't preloaded, and it requires more complex application logic.
