软件介绍
BigCache 是用于在 Go 中写入千兆字节数据的高效缓存。快速，并发，逐行扫描内存缓存，以保持大量条目，而不影响性能。 BigCache 在堆上保留条目，但为它们省略了 GC。 要实现对字节数组的操作，因此在大多数用例中将需要在高速缓存前面进行条目（de）序列化。
使用
简单初始化
import "github.com/allegro/bigcache"
cache, _ := bigcache.NewBigCache(bigcache.DefaultConfig(10 * time.Minute))
cache.Set("my-unique-key", []byte("value"))
entry, _ := cache.Get("my-unique-key")
fmt.Println(string(entry))自定义初始化
import (
"log"
"github.com/allegro/bigcache"
)
config := bigcache.Config {
// number of shards (must be a power of 2)
Shards: 1024,
// time after which entry can be evicted
LifeWindow: 10 * time.Minute,
// rps * lifeWindow, used only in initial memory allocation
MaxEntriesInWindow: 1000 * 10 * 60,
// max entry size in bytes, used only in initial memory allocation
MaxEntrySize: 500,
// prints information about additional memory allocation
Verbose: true,
// cache will not allocate more memory than this limit, value in MB
// if value is reached then the oldest entries can be overridden for the new ones
// 0 value means no size limit
HardMaxCacheSize: 8192,
// callback fired when the oldest entry is removed because of its
// expiration time or no space left for the new entry. Default value is nil which
// means no callback and it prevents from unwrapping the oldest entry.
OnRemove: nil,
}
cache, initErr := bigcache.NewBigCache(config)
if initErr != nil {
log.Fatal(initErr)
}
cache.Set("my-unique-key", []byte("value"))
if entry, err := cache.Get("my-unique-key"); err == nil {
fmt.Println(string(entry))
}
