Implement Key Expiration and Cache Eviction Policy

[ezrasingh]

Is your feature request related to a problem? Please describe.

I'm finding that without key expiration and a cache eviction policy, the system can become overwhelmed with stale or unnecessary data, leading to increased memory usage and reduced performance over time. This is especially problematic for large-scale applications where data is frequently updated or needs to be kept fresh.

Describe the solution you'd like

I'd like to implement support for key expiration and a cache eviction policy. This would allow us to automatically remove expired or least-recently-used (LRU) keys from the cache, ensuring that the system remains efficient and responsive. Key expiration would allow setting a time-to-live (TTL) for cache entries, after which they would be automatically evicted. The cache eviction policy would manage cache size by removing the least valuable entries when the cache reaches its capacity.

Describe alternatives you've considered

• Implementing a manual cleanup process where stale keys are removed during off-peak hours, though this may not be as efficient as automatic eviction.
• Using a third-party caching library that supports these features, but it would add external dependencies and might not integrate well with our current system architecture.

Additional context

Adding support for key expiration and cache eviction would improve overall system performance, reduce memory footprint, and ensure that only relevant data is retained in the cache. This feature could also provide better control over the cache behavior, adapting it to the specific needs of different applications.
