Pocache is a lightweight in-app caching package that optimizes performance in concurrent environments by preemptively updating cache entries nearing expiration, reducing redundant database calls. It features a configurable threshold window, serving stale values, and debouncing concurrent requests. The package uses Hashicorp’s Go LRU package as the default storage and allows for custom underlying storage. By triggering preemptive updates within a threshold window, Pocache ensures fresh data availability. The package helps prevent excessive I/O calls in highly concurrent environments, minimizing load on both the storage and the application. Pocache also supports custom error handling and configurable cache settings.
