What are the different caching strategies and how do they compare?

There are several caching strategies, including cache-aside, write-through, write-back, and time-based expiration. Each has its pros and cons depending on the use case.

Can you explain the cache-aside strategy in more detail?

Sure! In the cache-aside strategy, the application code is responsible for loading data into the cache. When data is requested, the application checks the cache first. If the data is not there, it retrieves it from the database and stores it in the cache for future requests.

What are the advantages of using write-through caching?

Write-through caching ensures that data is written to both the cache and the database simultaneously. This guarantees data consistency and reduces the risk of cache misses.

Are there any downsides to using write-back caching?

Yes, write-back caching can lead to data loss if the cache fails before the data is written to the database. It also adds complexity in managing cache coherence.
