When should I cache data in my application?

When should I cache data in my application?

Caching data can significantly improve performance. You should consider caching when data is frequently accessed, expensive to fetch, or doesn't change often.

What types of data are best suited for caching?

Data that is read frequently but updated infrequently is ideal for caching. Examples include user profiles, product listings, and configuration settings.

How do I decide the cache expiration time?

Cache expiration should be based on how often the data changes. For static data, a longer expiration is fine, while dynamic data may need shorter intervals.

Are there any downsides to caching?

Yes, caching can lead to stale data if not managed properly. It also adds complexity to your application, so it's important to weigh the benefits against the potential issues.
