A Memory-bound storage driver using dgraph-io/ristretto.
Note: Requires Go 1.19 and above
func New(config ...Config) Storage
func (s *Storage) Get(key string) ([]byte, error)
func (s *Storage) Set(key string, val []byte, exp time.Duration) error
func (s *Storage) Delete(key string) error
func (s *Storage) Reset() error
func (s *Storage) Close() error
func (s *Storage) Conn() *ristretto.CacheRistretto is tested on the 2 last Go versions with support for modules. So make sure to initialize one first if you didn't do that yet:
go mod init github.com/<user>/<repo>And then install the ristretto implementation:
go get github.com/gofiber/storage/ristretto/v2Import the storage package.
import "github.com/gofiber/storage/ristretto/v2"You can use the following possibilities to create a storage:
// Initialize default config
store := ristretto.New()
// Initialize custom config
store := ristretto.New(ristretto.Config{
NumCounters: 1e7, // number of keys to track frequency of (10M).
MaxCost: 1 << 30, // maximum cost of cache (1GB).
BufferItems: 64, // number of keys per Get buffer.
})type Config struct {
// NumCounters number of keys to track frequency of (10M).
NumCounters int64
// MaxCost maximum cost of cache (1GB).
MaxCost int64
// BufferItems number of keys per Get buffer.
BufferItems int64
}var ConfigDefault = Config{
