What are the differences between cache-aside and read-through caching?

Cache-aside and read-through are two caching strategies. In cache-aside, the application code is responsible for loading data into the cache. In read-through, the cache itself handles loading data from the database when a cache miss occurs.

Can you explain how cache-aside works in more detail?

Sure! In cache-aside, when an application needs data, it first checks the cache. If the data is not there (a cache miss), it retrieves it from the database and then stores it in the cache for future requests.

What about read-through caching? How does it differ in implementation?

In read-through caching, the cache automatically fetches data from the database when it is not found in the cache. This means the application doesn't need to handle the loading logic, simplifying the code.

Which caching strategy is generally more efficient?

It depends on the use case. Cache-aside can be more efficient for read-heavy applications, while read-through can simplify development and reduce cache misses.
