What is the difference between cache-aside and read-through caching?

What is the difference 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 give me an example of when to use each strategy?

Sure! Use cache-aside when you have unpredictable data access patterns, allowing more control over caching. Use read-through when you want to simplify your code and let the cache manage data loading.

What are the pros and cons of each approach?

Cache-aside offers flexibility and control but requires more code. Read-through simplifies code but can lead to performance issues if not managed properly.

Which strategy is more efficient in terms of performance?

It depends on your use case. Cache-aside can be more efficient for read-heavy applications, while read-through can be better for simpler implementations.
