What are some effective strategies for cache invalidation?
There are several strategies for cache invalidation, including time-based expiration, event-driven invalidation, and manual 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 cached data is considered stale and removed. This ensures that users receive fresh data without needing to manually clear the cache.
What about event-driven invalidation?
Event-driven invalidation triggers cache updates based on specific events, like data changes in the database. This method keeps the cache in sync with the underlying data.
Are there any downsides to these strategies?
Yes, time-based expiration can lead to stale data if not timed correctly, while event-driven invalidation can be complex to implement and may require additional resources.
