使用Redis和Golang构建实时监控系统：如何快速处理大量数据

package main

import (
    "fmt"
    "time"

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

func main() {
    client := redis.NewClient(&redis.Options{
        Addr:     "localhost:6379",
        Password: "", // 这里根据实际情况填写密码
        DB:       0,  // 默认数据库
    })

    // 设置当前时间戳
    timestamp := time.Now().Unix()

    // 添加数据到有序集合
    client.ZAdd("monitor", &redis.Z{
        Member: "data1",
        Score:  float64(timestamp),
    })
    client.ZAdd("monitor", &redis.Z{
        Member: "data2",
        Score:  float64(timestamp),
    })

    // 查询最新的数据
    res, _ := client.ZRevRangeByScore("monitor", &redis.ZRangeBy{
        Min:    "-inf",
        Max:    "+inf",
        Offset: 0,
        Count:  1,
    }).Result()

    fmt.Println(res)
}
