What are the limitations of the cache-aside pattern?

What are the limitations of the cache-aside pattern?

The cache-aside pattern has several limitations, including potential cache staleness, increased complexity, and performance overhead.

Can you explain what cache staleness means?

Cache staleness occurs when the data in the cache is outdated compared to the source of truth, leading to inconsistent reads.

How does this pattern compare to other caching strategies?

Compared to other strategies like write-through or write-behind, cache-aside requires more manual management and can be less efficient.

What scenarios is the cache-aside pattern best suited for?

It's best suited for read-heavy applications where data changes infrequently, allowing for effective caching.

Are there any best practices for implementing this pattern?

Yes, best practices include setting appropriate cache expiration times and monitoring cache performance regularly.
