What are cache consistency algorithms?

Cache consistency algorithms are methods used to ensure that multiple caches in a system reflect the same data state.

Why is cache consistency important in distributed systems?

It's crucial because it prevents data inconsistency and ensures that all nodes in a distributed system have the same view of data.

Can you explain some common cache consistency algorithms?

Sure! Some common algorithms include the write-through, write-back, and invalidation protocols.

How do these algorithms impact system performance?

They can significantly affect performance; for instance, write-through can slow down writes, while invalidation can reduce read latency.
