What are the key performance metrics for cache-aside caching?

What are the key performance metrics for cache-aside caching?

The key performance metrics for cache-aside caching include cache hit ratio, latency, throughput, and eviction rate.

How do I calculate the cache hit ratio?

The cache hit ratio is calculated by dividing the number of cache hits by the total number of cache accesses (hits + misses).

What is considered a good cache hit ratio?

A good cache hit ratio typically ranges from 70% to 90%, depending on the application and workload.

Can you explain latency and its importance?

Latency refers to the time taken to retrieve data from the cache. Lower latency improves application performance and user experience.
