What are the differences between various caching patterns?

Caching patterns can vary significantly. The main types include Cache-Aside, Read-Through, Write-Through, and Write-Behind. Each has its own use cases and performance implications.

Can you explain the Cache-Aside pattern in more detail?

Sure! In the Cache-Aside pattern, the application code is responsible for loading data into the cache. When data is needed, it first checks the cache; if it's not there, it retrieves it from the database and then stores it in the cache for future requests.

What are the pros and cons of using the Write-Through pattern?

The Write-Through pattern ensures that data is written to both the cache and the database simultaneously, which can simplify data consistency. However, it may introduce latency since every write operation involves both the cache and the database.

Which caching pattern would you recommend for a high-read, low-write application?

For a high-read, low-write application, the Cache-Aside pattern is often recommended. It allows for efficient reads while minimizing unnecessary writes to the database.
