Fast in-memory key:value store/cache with TTL

MCache library

go-mcache - this is a fast key:value storage. Its major advantage is that, being essentially a thread-safe .

map[string]interface{}

with expiration times, it doesn't need to serialize, and quick removal of expired keys.

Installation

~ $ go get -u github.com/OrlovEvgeny/go-mcache

Example a Pointer value (vary fast method)

type User struct {
	Name string
	Age  uint
	Bio  string
}

func main() {
	//Start mcache instance
	MCache = mcache.New()

	//Create custom key
	key := "custom_key1"
	//Create example struct
	user := &User{
		Name: "John",
		Age:  20,
		Bio:  "gopher 80 lvl",
	}

	//args - key, &value, ttl (or you need never delete, set ttl is mcache.TTL_FOREVER)
	err := MCache.Set(key, user, time.Minute*20)
	if err != nil {
		log.Fatal(err)
	}

	if data, ok := MCache.Get(key); ok {
		objUser:= data.(*User)
		fmt.Printf("User name: %s, Age: %d, Bio: %s\n", objUser.Name, objUser.Age, objUser.Bio)			
	}
}

Performance Benchmarks

goos: darwin
goarch: amd64
BenchmarkWrite-4          200000              7991 ns/op 
BenchmarkRead-4          1000000              1716 ns/op 
BenchmarkRW-4             300000              9894 ns/op

What should be done

• the possibility of closing
• r/w benchmark statistics
• rejection of channels in safeMap in favor of sync.Mutex (there is an opinion that it will be faster)
