cache

🪡cache

a simple cache framework for golang

introduction

This is a cache framework implemented by Golang. This framework implements the FIFO and LRU algorithms for managing cache and is thread safe. The algorithm needs to be selected based on the actual situation, and using FIFO in an environment with more reads and less writes will result in higher performance.

installing

Select the version to install

go get github.com/go-needle/cache@version

If you have already get , you may need to update to the latest version

go get -u github.com/go-needle/cache

quickly start

package main

import (
	"fmt"
	"github.com/go-needle/cache"
	"math/rand"
	"strconv"
	"time"
)

func main() {
	c := cache.NewLRU(1024, time.Duration(10)*time.Second)
	//c := cache.NewFIFO(1<<32, time.Duration(10)*time.Second)
	for i := 0; i < 1000; i++ {
		num := i
		go func() {
			time.Sleep(time.Duration(rand.Intn(10)) * time.Second)
			c.Add("key"+strconv.Itoa(num), []byte(strconv.Itoa(num)))
		}()
	}
	for i := 0; i < 1000; i++ {
		num := i
		go func() {
			time.Sleep(time.Duration(rand.Intn(20)) * time.Second)
			v, ok := c.Get("key" + strconv.Itoa(num))
			fmt.Println(v.String(), ok)
		}()
	}
	time.Sleep(time.Duration(20) * time.Second)
}
