What are some effective cache invalidation strategies in Ruby?

There are several strategies for cache invalidation in Ruby, such as time-based expiration, versioning, and event-driven invalidation. Would you like to explore any of these in detail?

Can you explain time-based expiration?

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

What about versioning?

Versioning involves associating a version number with cached data. When the underlying data changes, you increment the version number, which forces the cache to refresh.

How does event-driven invalidation work?

Event-driven invalidation triggers cache updates based on specific events, like database changes. When an event occurs, the cache is invalidated or updated accordingly.
