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

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

The cache-aside pattern allows the application to manage the cache, loading data into it only when needed. In contrast, the read-through cache pattern automatically loads data into the cache when it's requested, abstracting the cache management from the application.

Can you give me an example of when to use each pattern?

Sure! Use cache-aside when you have infrequent reads and want to control cache loading. Use read-through when you have frequent reads and want to simplify cache management.

What are the pros and cons of each pattern?

Cache-aside offers flexibility and control but requires more management. Read-through simplifies access but can lead to cache pollution if not managed properly.

Which pattern is more efficient in terms of performance?

It depends on your use case. Cache-aside can be more efficient for specific access patterns, while read-through can improve performance for high-frequency reads.
