Features

• Go In-Memory Caches - Provides an in-memory key-value store for Go applications with configurable expiration and concurrent access.
• Concurrent Caches - Shares a cache safely across multiple goroutines without manual locking or race conditions.
• Lazy Expiration - Checks expiration timestamps during cache access and periodic sweeps to remove stale entries.
• In-Memory Caches - Stores frequently accessed data in memory to reduce latency and database load for single-machine applications.
• Key-Value Stores - Provides a simple in-memory key-value store as a lightweight alternative to external caching systems.
• RWMutex-Guarded Stores - Uses a sync.RWMutex to allow multiple readers or a single writer without race conditions.
• Cache Expiration Management - Automatically removes cached items after a configurable duration to ensure data freshness.
• Time-To-Live Expirations - Attaches a creation time and duration to each cached entry for precise expiration checks.
• Background Cleanup Intervals - Provides a background goroutine that periodically purges expired cache entries at configurable intervals.
• Cache State Persistences - Saves the in-memory cache to a file and reloads it on startup for recovery after restarts.
• Cache-to-Disk Serializations - Persists the in-memory cache to a file and reloads it on startup to recover from downtime.
• Cache State Serializations - Serializes the entire cache to a file using gob encoding for disk persistence and recovery after restarts.
• Caching Libraries - Simple in-memory KV cache.
• Databases and Storage - A simple in-memory key-value store for single-node applications.
