A memory cache with go

memcache is a go package for memory cache

Quick Start

Install memcache

go get -u -v github.com/ohmountain/memcache

Use memcache

package main

import "time"
import "github.com/ohmountain/memcache"

func main() {
    // Use memcache without ttl
    cache := memcache.WithLRU(10000, false);
    cache.Set("Hello", "World");
    cache.Get("Hello")  // "World"
    cache.Get("world")  // nil 

    // Use memcache with ttl
    cache = memcache.WithLRU(10000, true)
    cache.SetExpire("Some", "Thing", 10)  // 10 seconds to live
    cache.Get("Some")  // "Thing"
    time.Sleep(11 * time.Second)
    cache.Get("Some")  // nil

    // Or delete
    cache.Set("Haha", "Huhu")
    cache.Delete("Haha") 
}

Difference between TTL and Non-TTL

If ttl is not used, it is just an LRU memory cache; if ttl is used, then it adds a mechanism of expiration by time on the basis of LRU, which means that even if the LRU mechanism does not take effect, the buffer will automatically clean up expired k/v.
