## ttlcache

`ttlcache` is an in-process object caching library designed specifically for managing the caching and automatic release of objects with lifecycles. The cache operates on a time-based expiration mechanism, measured in seconds, and utilizes timestamp caching to avoid real-time system time retrieval. This significantly improves efficiency. Object storage employs sharding techniques to reduce concurrent access competition.

Usage:

```

import "github.com/shaovie/ttlcache"

func main() {

	cache := ttlcache.New(ttlcache.BucketsCount(512),

		ttlcache.BucketsMapPreAllocSize(256),

		ttlcache.CleanInterval(10),

	)

	cache.Set("ttlcache", "nb", 1/*second*/) // The lifecycle is 1 second

	val, found := cache.Get("ttlcache")

	if !found {

		fmt.Println("set val error")

		return

	}

	time.Sleep(time.Millisecond * 1500)

	_, found = cache.Get("ttlcache")

	if !found {

		fmt.Println("expired")

	}

}

```
