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

Cache-aside and read-through cache are two caching strategies. In cache-aside, the application code is responsible for loading data into the cache. In read-through cache, 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 infrequent reads and want to control cache population. Use read-through when you have high read frequency and want to simplify cache management.

What are the pros and cons of each approach?

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

Which strategy is more efficient?

Efficiency depends on your specific use case. Cache-aside can be more efficient for less frequent reads, while read-through can be better for high-frequency access.
