What is the impact of cache consistency in distributed systems?

Cache consistency ensures that all nodes in a distributed system have the same view of data, which is crucial for data integrity.

Why is it important to maintain cache consistency?

Maintaining cache consistency prevents stale data from being served, which can lead to incorrect application behavior and user experience.

What are some common strategies for achieving cache consistency?

Common strategies include write-through, write-back, and invalidation protocols, each with its own trade-offs.

Can you explain the trade-offs of these strategies?

Sure! Write-through ensures data is always consistent but can be slower, while write-back is faster but risks data loss if a failure occurs.
