When should I use write-through caching?

What is write-through caching and when should I use it?

Write-through caching is a caching strategy where data is written to both the cache and the underlying storage simultaneously. You should use it when data consistency is critical, as it ensures that the cache always has the most up-to-date information.

What are the benefits of using write-through caching?

The main benefits include improved data consistency, reduced risk of data loss, and simplified cache management since the cache is always in sync with the database.

Are there any downsides to using write-through caching?

Yes, the downsides include potential performance bottlenecks due to the synchronous nature of writes, which can slow down write operations.

In what scenarios is write-through caching not recommended?

It's not recommended in scenarios where write performance is critical, or when the application can tolerate eventual consistency, as other caching strategies like write-back caching may be more efficient.
