What are the best cache invalidation strategies?

What are the best cache invalidation strategies I should consider?

There are several effective cache invalidation strategies, including time-based expiration, event-based invalidation, and manual invalidation. Each has its pros and cons depending on your use case.

Can you explain time-based expiration?

Time-based expiration involves setting a specific time after which cached data is considered stale and is removed or refreshed. This is useful for data that changes predictably.

What about event-based invalidation?

Event-based invalidation triggers cache updates based on specific events, like data changes in the database. This ensures that the cache is always up-to-date with the latest information.

Which strategy is the most efficient?

The most efficient strategy often depends on your application's needs. For dynamic data, event-based invalidation is usually best, while for static data, time-based expiration can be sufficient.
