What are the different types of cache strategies?

There are several types of cache strategies, including write-through, write-back, and cache-aside. Would you like to know more about each?

Yes, please explain write-through and write-back caching.

In write-through caching, data is written to both the cache and the underlying storage simultaneously. In contrast, write-back caching only writes to the cache initially, updating the storage later. This can improve performance but may risk data loss if the cache fails.

What are the advantages of using cache-aside?

Cache-aside allows applications to load data into the cache on demand, which can reduce unnecessary data loading and improve performance. It also gives more control over cache management.

Are there any downsides to caching?

Yes, caching can introduce complexity, potential data staleness, and increased memory usage. It's important to implement proper cache invalidation strategies.
