redis 存日志_session用redis存好吗

package main

import (
"fmt"
"time"

"github.com/go-redis/redis"
)

func main() {
start := time.Now()
client := redis.NewClient(redis.Options{
Addr: "12⑦0.0.1:6379",
})
err := client.Ping().Err()
if err != nil {
panic(err.Error())
}
for i := 0; i < 1000000; i++ {
now := time.Now()
nowStr := fmt.Sprintf("%d-%d-%d d:d:d", now.Year(), now.Month(), now.Day(), now.Hour(), now.Minute(), now.Second())
client.LPush("log", nowStr+" 200 success laskdjflaskjdflkjasdl")
}
fmt.Println(time.Since(start))
}

package main

import (
"fmt"
"os"
"time"
)

func main() {
file, err := os.Create("test.log")
if err != nil {
panic(err.Error())
}
start := time.Now()
for i := 0; i < 1000000; i++ {
now := time.Now()
nowStr := fmt.Sprintf("%d-%d-%d d:d:d", now.Year(), now.Month(), now.Day(), now.Hour(), now.Minute(), now.Second())
fmt.Fprintln(file, nowStr, "200", "success", "", "laksjdflkjsdal")
}
fmt.Println("time:", time.Since(start))
}

不对时间进行格式化处理时

对时间进行格式化处理后

可见redis和直接的fmt输出到文件,速度差了十倍左右

但用redis存日志查起来比较容易查,还可以将日期附加到key里区分每一天的日志,具体用文件存储还是redis按需求来
