Cache Invalidation

Showcasing Different Cache Invalidation Strategies (Time, Write-Through, Least Recently Used, Event, Version, Invalidate-On-Change, Distributed Caching)

Strategies

• Time-based Expiration: Using go-cache to expire items after a certain duration (time.go).
• Manual Invalidation: Deleting cache entries directly (distributed.go).
• Versioned Cache: Associating a version with each cache entry and updating the version when the data changes (version.go).
• Write-Through Cache: Updating the cache whenever the underlying data source is updated (wtc.go).
• Event-Based Invalidation: Using Redis Pub/Sub to broadcast invalidation events to other cache instances (event.go).
• Invalidate with Callbacks: Using callbacks to trigger functions on invalidation (ioc.go).
