What is write-through caching and how does it work?

Write-through caching is a caching strategy where data is written to both the cache and the underlying storage simultaneously. This ensures that the cache always has the most up-to-date data.

What are the advantages of using write-through caching?

The main advantages include data consistency, easier recovery from failures, and reduced complexity in managing cache coherence.

Are there any downsides to write-through caching?

Yes, it can lead to slower write operations since every write must be done twice, and it may increase the load on the underlying storage.

In what scenarios is write-through caching most beneficial?

It's most beneficial in applications where data consistency is critical, such as financial systems or real-time data processing.
