What are the drawbacks of the cache-aside strategy?

What are the drawbacks of the cache-aside strategy?

The cache-aside strategy can lead to stale data, increased complexity, and potential performance bottlenecks.

Can you explain how stale data occurs in this strategy?

Stale data occurs when the cache is not updated immediately after a change in the underlying data store, leading to outdated information being served.

What can be done to mitigate these drawbacks?

To mitigate these drawbacks, you can implement cache expiration policies, use write-through caching, or regularly refresh the cache.

Are there scenarios where cache-aside is still a good choice?

Yes, cache-aside can be beneficial in read-heavy applications where data changes infrequently, allowing for improved performance.
