What are some effective strategies for cache consistency?

There are several strategies for maintaining cache consistency, including write-through, write-back, and cache invalidation.

Can you explain the write-through strategy?

Sure! In the write-through strategy, data is written to both the cache and the underlying data store simultaneously, ensuring consistency.

What are the pros and cons of using cache invalidation?

Cache invalidation can reduce stale data but may lead to increased latency as data must be fetched from the source more often.

Are there any specific scenarios where one strategy is preferred over others?

Yes, for example, write-back is often preferred in high-write environments, while write-through is better for read-heavy applications.
