What is write-through caching?

Can you explain what write-through caching is?

Sure! Write-through caching is a caching strategy where data is written to both the cache and the underlying storage simultaneously.

What are the benefits of using write-through caching?

The main benefits include data consistency and reliability, as the cache always has the most up-to-date information.

Are there any downsides to this approach?

Yes, it can lead to slower write operations since every write must be done twice, which may impact performance.

How does it compare to write-back caching?

In write-back caching, data is written only to the cache initially, and the underlying storage is updated later, which can improve performance but risks data loss if the cache fails.
