What are some common issues with caching?

Common issues with caching include stale data, cache misses, and cache thrashing. Would you like to know more about any specific issue?

What is stale data?

Stale data occurs when the cache holds outdated information that doesn't reflect the current state of the data source. This can lead to inconsistencies.

How can I prevent stale data?

You can prevent stale data by implementing cache expiration policies, using cache invalidation strategies, or refreshing the cache periodically.

What is a cache miss?

A cache miss happens when the requested data is not found in the cache, leading to a fallback to the original data source, which can slow down performance.

What is cache thrashing?

Cache thrashing occurs when the cache is constantly being filled and emptied, often due to poor cache size or inappropriate caching strategies, leading to reduced performance.
